+ Generic PWM Device API
+
+ February 1, 2010
+ Bill Gatliff
+ <bgat@billgatliff.com>
+
+
+
+The code in drivers/pwm and include/linux/pwm/ implements an API for
+applications involving pulse-width-modulation signals. This document
+describes how the API implementation facilitates both PWM-generating
+devices, and users of those devices.
+
+
+
+Motivation
+
+The primary goals for implementing the "generic PWM API" are to
+consolidate the various PWM implementations within a consistent and
+redundancy-reducing framework, and to facilitate the use of
+hotpluggable PWM devices.
+
+Previous PWM-related implementations within the Linux kernel achieved
+their consistency via cut-and-paste, but did not need to (and didn't)
+facilitate more than one PWM-generating device within the system---
+hotplug or otherwise. The Generic PWM Device API might be most
+appropriately viewed as an update to those implementations, rather
+than a complete rewrite.
+
+
+
+Challenges
+
+One of the difficulties in implementing a generic PWM framework is the
+fact that pulse-width-modulation applications involve real-world
+signals, which often must be carefully managed to prevent destruction
+of hardware that is linked to those signals. A DC motor that
+experiences a brief interruption in the PWM signal controlling it
+might destructively overheat; it could suddenly change speed, losing
+synchronization with a sensor; it could even suddenly change direction
+or torque, breaking the mechanical device connected to it.
+
+(A generic PWM device framework is not directly responsible for
+preventing the above scenarios: that responsibility lies with the
+hardware designer, and the application and driver authors. But it
+must to the greatest extent possible make it easy to avoid such
+problems).
+
+A generic PWM device framework must accommodate the substantial
+differences between available PWM-generating hardware devices, without
+becoming sub-optimal for any of them.
+
+Finally, a generic PWM device framework must be relatively
+lightweight, computationally speaking. Some PWM users demand
+high-speed outputs, plus the ability to regulate those outputs
+quickly. A device framework must be able to "keep up" with such
+hardware, while still leaving time to do real work.
+
+The Generic PWM Device API is an attempt to meet all of the above
+requirements. At its initial publication, the API was already in use
+managing small DC motors, sensors and solenoids through a
+custom-designed, optically-isolated H-bridge driver.
+
+
+
+Functional Overview
+
+The Generic PWM Device API framework is implemented in
+include/linux/pwm/pwm.h and drivers/pwm/pwm.c. The functions therein
+use information from pwm_device, pwm_channel and pwm_channel_config
+structures to invoke services in PWM peripheral device drivers.
+Consult drivers/pwm/atmel-pwm.c for an example driver.
+
+There are two classes of adopters of the PWM framework:
+
+ "Users" -- those wishing to employ the API merely to produce PWM
+ signals; once they have identified the appropriate physical output
+ on the platform in question, they don't care about the details of
+ the underlying hardware
+
+ "Driver authors" -- those wishing to bind devices that can generate
+ PWM signals to the Generic PWM Device API, so that the services of
+ those devices become available to users. Assuming the hardware can
+ support the needs of a user, driver authors don't care about the
+ details of the user's application
+
+Generally speaking, users will first invoke pwm_request() to obtain a
+handle to a PWM device. They will then pass that handle to functions
+like pwm_duty_ns() and pwm_period_ns() to set the duty cycle and
+period of the PWM signal, respectively. They will also invoke
+pwm_start() and pwm_stop() to turn the signal on and off.
+
+The Generic PWM API framework also provides a sysfs interface to PWM
+devices, which is adequate for basic application needs and testing.
+
+Driver authors fill out a pwm_device structure, which describes the
+capabilities of the PWM hardware being constructed--- including the
+number of distinct output "channels" the peripheral offers. They then
+invoke pwm_register() (usually from within their device's probe()
+handler) to make the PWM API aware of their device. The framework
+will call back to the methods described in the pwm_device structure as
+users begin to configure and utilize the hardware.
+
+Note that PWM signals can be produced by a variety of peripherals,
+beyond the true "PWM hardware" offered by many system-on-chip devices.
+Other possibilities include timer/counters with compare-match
+capabilities, carefully-programmed synchronous serial ports
+(e.g. SPI), and GPIO pins driven by kernel interval timers. With a
+proper pwm_device structure, these devices and pseudo-devices can all
+be accommodated by the Generic PWM Device API framework.
+
+
+
+Using the API to Generate PWM Signals -- Basic Functions for Users
+
+
+pwm_request() -- Returns a pwm_channel pointer, which is subsequently
+passed to the other user-related PWM functions. Once requested, a PWM
+channel is marked as in-use and subsequent requests prior to
+pwm_free() will fail.
+
+The names used to refer to PWM devices are defined by driver authors.
+Typically they are platform device bus identifiers, and this
+convention is encouraged for consistency.
+
+
+pwm_free() -- Marks a PWM channel as no longer in use. The PWM device
+is stopped before it is released by the API.
+
+
+pwm_period_ns() -- Specifies the PWM signal's period, in nanoseconds.
+
+
+pwm_duty_ns() -- Specifies the PWM signal's active duration, in nanoseconds.
+
+
+pwm_duty_percent() -- Specifies the PWM signal's active duration, as a
+percentage of the current period of the signal. NOTE: this value is
+not recalculated if the period of the signal is subsequently changed.
+
+
+pwm_start(), pwm_stop() -- Turns the PWM signal on and off. Except
+where stated otherwise by a driver author, signals are stopped at the
+end of the current period, at which time the output is set to its
+inactive state.
+
+
+pwm_polarity() -- Defines whether the PWM signal output's active
+region is "1" or "0". A 10% duty-cycle, polarity=1 signal will
+conventionally be at 5V (or 3.3V, or 1000V, or whatever the platform
+hardware does) for 10% of the period. The same configuration of a
+polarity=0 signal will be at 5V (or 3.3V, or ...) for 90% of the
+period.
+
+
+
+Using the API to Generate PWM Signals -- Advanced Functions
+
+
+pwm_config() -- Passes a pwm_channel_config structure to the
+associated device driver. This function is invoked by pwm_start(),
+pwm_duty_ns(), etc. and is one of two main entry points to the PWM
+driver for the hardware being used. The configuration change is
+guaranteed atomic if multiple configuration changes are specified.
+This function might sleep, depending on what the device driver has to
+do to satisfy the request. All PWM device drivers must support this
+entry point.
+
+
+pwm_config_nosleep() -- Passes a pwm_channel_config structure to the
+associated device driver. If the driver must sleep in order to
+implement the requested configuration change, -EWOULDBLOCK is
+returned. Users may call this function from interrupt handlers, for
+example. This is the other main entry point into the PWM hardware
+driver, but not all device drivers support this entry point.
+
+
+pwm_synchronize(), pwm_unsynchronize() -- "Synchronizes" two or more
+PWM channels, if the underlying hardware permits. (If it doesn't, the
+framework facilitates emulating this capability but it is not yet
+implemented). Synchronized channels will start and stop
+simultaneously when any single channel in the group is started or
+stopped. Use pwm_unsynchronize(..., NULL) to completely detach a
+channel from any other synchronized channels. By default, all PWM
+channels are unsynchronized.
+
+
+pwm_set_handler() -- Defines an end-of-period callback. The indicated
+function will be invoked in a worker thread at the end of each PWM
+period, and can subsequently invoke pwm_config(), etc. Must be used
+with extreme care for high-speed PWM outputs. Set the handler
+function to NULL to un-set the handler.
+
+
+
+Implementing a PWM Device API Driver -- Functions for Driver Authors
+
+
+Fill out the appropriate fields in a pwm_device structure, and submit
+to pwm_register():
+
+
+bus_id -- the plain-text name of the device. Users will bind to a
+channel on the device using this name plus the channel number. For
+example, the Atmel PWMC's bus_id is "atmel_pwmc", the same as used by
+the platform device driver (recommended). The first device registered
+thereby receives bus_id "atmel_pwmc.0", which is what you put in
+pwm_device.bus_id. Channels are then named "atmel_pwmc.0:[0-3]".
+(Hint: just use pdev->dev.bus_id in your probe() method).
+
+
+nchan -- the number of distinct output channels provided by the device.
+
+
+request -- (optional) Invoked each time a user requests a channel.
+Use to turn on clocks, clean up register states, etc. The framework
+takes care of device locking/unlocking; you will see only successful
+requests.
+
+
+free -- (optional) Callback for each time a user relinquishes a
+channel. The framework will have already stopped, unsynchronized and
+un-handled the channel. Use to turn off clocks, etc. as necessary.
+
+
+synchronize, unsynchronize -- (optional) Callbacks to
+synchronize/unsynchronize channels. Some devices provide this
+capability in hardware; for others, it can be emulated (see
+atmel_pwmc.c's sync_mask for an example).
+
+
+set_callback -- (optional) Invoked when a user requests a handler. If
+the hardware supports an end-of-period interrupt, invoke the function
+indicated during your interrupt handler. The callback function itself
+is always internal to the API, and does not map directly to the user's
+callback function.
+
+
+config -- Invoked to change the device configuration, always from a
+sleep-capable context. All the changes indicated must be performed
+atomically, ideally synchronized to an end-of-period event (so that
+you avoid short or long output pulses). You may sleep, etc. as
+necessary within this function.
+
+
+config_nosleep -- (optional) Invoked to change device configuration
+from within a context that is not allowed to sleep. If you cannot
+perform the requested configuration changes without sleeping, return
+-EWOULDBLOCK.
+
+

+have reviewed and submitted feedback on the various versions of the
+Generic PWM Device API code, and those who have submitted drivers and
+applications that use the framework. You know who you are. ;)

+README - ocf-linux-20100325
+---------------------------
+
+This README provides instructions for getting ocf-linux compiled and
+operating in a generic linux environment. For other information you
+might like to visit the home page for this project:
+
+ http://ocf-linux.sourceforge.net/
+
+Adding OCF to linux
+-------------------
+
+ Not much in this file for now, just some notes. I usually build
+ the ocf support as modules but it can be built into the kernel as
+ well. To use it:
+
+ * mknod /dev/crypto c 10 70
+
+ * to add OCF to your kernel source, you have two options. Apply
+ the kernel specific patch:
+
+ cd linux-2.4*; gunzip < ocf-linux-24-XXXXXXXX.patch.gz | patch -p1
+ cd linux-2.6*; gunzip < ocf-linux-26-XXXXXXXX.patch.gz | patch -p1
+
+ if you do one of the above, then you can proceed to the next step,
+ or you can do the above process by hand with using the patches against
+ linux-2.4.35 and 2.6.33 to include the ocf code under crypto/ocf.
+ Here's how to add it:
+
+ for 2.4.35 (and later)
+
+ cd linux-2.4.35/crypto
+ tar xvzf ocf-linux.tar.gz
+ cd ..
+ patch -p1 < crypto/ocf/patches/linux-2.4.35-ocf.patch
+
+ for 2.6.23 (and later), find the kernel patch specific (or nearest)
+ to your kernel versions and then:
+
+ cd linux-2.6.NN/crypto
+ tar xvzf ocf-linux.tar.gz
+ cd ..
+ patch -p1 < crypto/ocf/patches/linux-2.6.NN-ocf.patch
+
+ It should be easy to take this patch and apply it to other more
+ recent versions of the kernels. The same patches should also work
+ relatively easily on kernels as old as 2.6.11 and 2.4.18.
+
+ * under 2.4 if you are on a non-x86 platform, you may need to:
+
+ cp linux-2.X.x/include/asm-i386/kmap_types.h linux-2.X.x/include/asm-YYY
+
+ so that you can build the kernel crypto support needed for the cryptosoft
+ driver.
+
+ * For simplicity you should enable all the crypto support in your kernel
+ except for the test driver. Likewise for the OCF options. Do not
+ enable OCF crypto drivers for HW that you do not have (for example
+ ixp4xx will not compile on non-Xscale systems).
+
+ * make sure that cryptodev.h (from ocf-linux.tar.gz) is installed as
+ crypto/cryptodev.h in an include directory that is used for building
+ applications for your platform. For example on a host system that
+ might be:
+
+ /usr/include/crypto/cryptodev.h
+
+ * patch your openssl-0.9.8n code with the openssl-0.9.8n.patch.
+ (NOTE: there is no longer a need to patch ssh). The patch is against:
+ openssl-0_9_8e
+
+ If you need a patch for an older version of openssl, you should look
+ to older OCF releases. This patch is unlikely to work on older
+ openssl versions.
+
+ openssl-0.9.8n.patch
+ - enables --with-cryptodev for non BSD systems
+ - adds -cpu option to openssl speed for calculating CPU load
+ under linux
+ - fixes null pointer in openssl speed multi thread output.
+ - fixes test keys to work with linux crypto's more stringent
+ key checking.
+ - adds MD5/SHA acceleration (Ronen Shitrit), only enabled
+ with the --with-cryptodev-digests option
+ - fixes bug in engine code caching.
+
+ * build crypto-tools-XXXXXXXX.tar.gz if you want to try some of the BSD
+ tools for testing OCF (ie., cryptotest).
+
+How to load the OCF drivers
+---------------------------
+
+ First insert the base modules:
+
+ insmod ocf
+ insmod cryptodev
+
+ You can then install the software OCF driver with:
+
+ insmod cryptosoft
+
+ and one or more of the OCF HW drivers with:
+
+ insmod safe
+ insmod hifn7751
+ insmod ixp4xx
+ ...
+
+ all the drivers take a debug option to enable verbose debug so that
+ you can see what is going on. For debug you load them as:
+
+ insmod ocf crypto_debug=1
+ insmod cryptodev cryptodev_debug=1
+ insmod cryptosoft swcr_debug=1
+
+ You may load more than one OCF crypto driver but then there is no guarantee
+ as to which will be used.
+
+ You can also enable debug at run time on 2.6 systems with the following:
+
+ echo 1 > /sys/module/ocf/parameters/crypto_debug
+ echo 1 > /sys/module/cryptodev/parameters/cryptodev_debug
+ echo 1 > /sys/module/cryptosoft/parameters/swcr_debug
+ echo 1 > /sys/module/hifn7751/parameters/hifn_debug
+ echo 1 > /sys/module/safe/parameters/safe_debug
+ echo 1 > /sys/module/ixp4xx/parameters/ixp_debug
+ ...
+
+Testing the OCF support
+-----------------------
+
+ run "cryptotest", it should do a short test for a couple of
+ des packets. If it does everything is working.
+
+ If this works, then ssh will use the driver when invoked as:
+
+ ssh -c 3des username@host
+
+ to see for sure that it is operating, enable debug as defined above.
+
+ To get a better idea of performance run:
+
+ cryptotest 100 4096
+
+ There are more options to cryptotest, see the help.
+
+ It is also possible to use openssl to test the speed of the crypto
+ drivers.
+
+ openssl speed -evp des -engine cryptodev -elapsed
+ openssl speed -evp des3 -engine cryptodev -elapsed
+ openssl speed -evp aes128 -engine cryptodev -elapsed
+
+ and multiple threads (10) with:
+
+ openssl speed -evp des -engine cryptodev -elapsed -multi 10
+ openssl speed -evp des3 -engine cryptodev -elapsed -multi 10
+ openssl speed -evp aes128 -engine cryptodev -elapsed -multi 10
+
+ for public key testing you can try:
+
+ cryptokeytest
+ openssl speed -engine cryptodev rsa -elapsed
+ openssl speed -engine cryptodev dsa -elapsed

+ * hifn_command_t
+ *
+ * This is the control structure used to pass commands to hifn_encrypt().
+ *
+ * flags
+ * -----
+ * Flags is the bitwise "or" values for command configuration. A single
+ * encrypt direction needs to be set:
+ *
+ * HIFN_ENCODE or HIFN_DECODE
+ *
+ * To use cryptography, a single crypto algorithm must be included:
+ *
+ * HIFN_CRYPT_3DES or HIFN_CRYPT_DES
+ *
+ * To use authentication is used, a single MAC algorithm must be included:
+ *
+ * HIFN_MAC_MD5 or HIFN_MAC_SHA1
+ *
+ * By default MD5 uses a 16 byte hash and SHA-1 uses a 20 byte hash.
+ * If the value below is set, hash values are truncated or assumed
+ * truncated to 12 bytes:
+ *
+ * HIFN_MAC_TRUNC
+ *
+ * Keys for encryption and authentication can be sent as part of a command,
+ * or the last key value used with a particular session can be retrieved
+ * and used again if either of these flags are not specified.
+ *
+ * HIFN_CRYPT_NEW_KEY, HIFN_MAC_NEW_KEY
+ *
+ * session_num
+ * -----------
+ * A number between 0 and 2048 (for DRAM models) or a number between
+ * 0 and 768 (for SRAM models). Those who don't want to use session
+ * numbers should leave value at zero and send a new crypt key and/or
+ * new MAC key on every command. If you use session numbers and
+ * don't send a key with a command, the last key sent for that same
+ * session number will be used.
+ *
+ * Warning: Using session numbers and multiboard at the same time
+ * is currently broken.
+ *
+ * mbuf
+ * ----
+ * Either fill in the mbuf pointer and npa=0 or
+ * fill packp[] and packl[] and set npa to > 0
+ *
+ * mac_header_skip
+ * ---------------
+ * The number of bytes of the source_buf that are skipped over before
+ * authentication begins. This must be a number between 0 and 2^16-1
+ * and can be used by IPsec implementers to skip over IP headers.
+ * *** Value ignored if authentication not used ***
+ *
+ * crypt_header_skip
+ * -----------------
+ * The number of bytes of the source_buf that are skipped over before
+ * the cryptographic operation begins. This must be a number between 0
+ * and 2^16-1. For IPsec, this number will always be 8 bytes larger
+ * than the auth_header_skip (to skip over the ESP header).
+ * *** Value ignored if cryptography not used ***

+* mvDramIfDetect - Prepare DRAM interface configuration values.
+*
+* DESCRIPTION:
+* This function implements the full DRAM detection and timing
+* configuration for best system performance.
+* Since this routine runs from a ROM device (Boot Flash), its stack
+* resides on RAM, that might be the system DRAM. Changing DRAM
+* configuration values while keeping vital data in DRAM is risky. That
+* is why the function does not preform the configuration setting but
+* prepare those in predefined 32bit registers (in this case IDMA
+* registers are used) for other routine to perform the settings.
+* The function will call for board DRAM SPD information for each DRAM
+* chip select. The function will then analyze those SPD parameters of
+* all DRAM banks in order to decide on DRAM configuration compatible
+* for all DRAM banks.
+* The function will set the CPU DRAM address decode registers.
+* Note: This routine prepares values that will overide configuration of
+* mvDramBasicAsmInit().
+*
+* INPUT:
+* forcedCl - Forced CAL Latency. If equal to zero, do not force.
+*
+* OUTPUT:
+* None.
+*
+* RETURN:
+* None.

+* mvDramIfDetect - Prepare DRAM interface configuration values.
+*
+* DESCRIPTION:
+* This function implements the full DRAM detection and timing
+* configuration for best system performance.
+* Since this routine runs from a ROM device (Boot Flash), its stack
+* resides on RAM, that might be the system DRAM. Changing DRAM
+* configuration values while keeping vital data in DRAM is risky. That
+* is why the function does not preform the configuration setting but
+* prepare those in predefined 32bit registers (in this case IDMA
+* registers are used) for other routine to perform the settings.
+* The function will call for board DRAM SPD information for each DRAM
+* chip select. The function will then analyze those SPD parameters of
+* all DRAM banks in order to decide on DRAM configuration compatible
+* for all DRAM banks.
+* The function will set the CPU DRAM address decode registers.
+* Note: This routine prepares values that will overide configuration of
+* mvDramBasicAsmInit().
+*
+* INPUT:
+* forcedCl - Forced CAL Latency. If equal to zero, do not force.
+* eccDisable - Force down the ECC.
+*
+* OUTPUT:
+* None.
+*
+* RETURN:
+* None.

+* mvEth.c - Marvell's Gigabit Ethernet controller low level driver
+*
+* DESCRIPTION:
+* This file introduce OS independent APIs to Marvell's Gigabit Ethernet
+* controller. This Gigabit Ethernet Controller driver API controls
+* 1) Operations (i.e. port Init, Finish, Up, Down, PhyReset etc').
+* 2) Data flow (i.e. port Send, Receive etc').
+* 3) MAC Filtering functions (ethSetMcastAddr, ethSetRxFilterMode, etc.)
+* 4) MIB counters support (ethReadMibCounter)
+* 5) Debug functions (ethPortRegs, ethPortCounters, ethPortQueues, etc.)
+* Each Gigabit Ethernet port is controlled via ETH_PORT_CTRL struct.
+* This struct includes configuration information as well as driver
+* internal data needed for its operations.
+*
+* Supported Features:
+* - OS independent. All required OS services are implemented via external
+* OS dependent components (like osLayer or ethOsg)
+* - The user is free from Rx/Tx queue managing.
+* - Simple Gigabit Ethernet port operation API.
+* - Simple Gigabit Ethernet port data flow API.
+* - Data flow and operation API support per queue functionality.
+* - Support cached descriptors for better performance.
+* - PHY access and control API.
+* - Port Configuration API.
+* - Full control over Special and Other Multicast MAC tables.

+*
+* Assumptions :
+* Bar0 is always internal registers bar
+* Bar1 is always the DRAM bar
+* Bar2 is always the Device bar
+*
+* 1) Sets the Internal registers bar base by obtaining the base from
+* the CPU Interface
+* 2) Sets the DRAM bar base and size by getting the base and size from
+* the CPU Interface when the size is the sum of all enabled DRAM
+* chip selects and the base is the base of CS0 .
+* 3) Sets the Device bar base and size by getting these values from the
+* CPU Interface when the base is the base of the lowest base of the
+* Device chip selects, and the
+*
+*
+* INPUT:
+*
+* pexIf - PEX interface number.
+*
+*
+* OUTPUT:
+* None.
+*
+* RETURN:

+ * ---------------------------------------------------------------------------
+ *
+ * NOTES:
+ *
+ * The Freescale SEC (also known as 'talitos') resides on the
+ * internal bus, and runs asynchronous to the processor core. It has
+ * a wide gamut of cryptographic acceleration features, including single-
+ * pass IPsec (also known as algorithm chaining). To properly utilize
+ * all of the SEC's performance enhancing features, further reworking
+ * of higher level code (framework, applications) will be necessary.
+ *
+ * The following table shows which SEC version is present in which devices:
+ *
+ * Devices SEC version
+ *
+ * 8272, 8248 SEC 1.0
+ * 885, 875 SEC 1.2
+ * 8555E, 8541E SEC 2.0
+ * 8349E SEC 2.01
+ * 8548E SEC 2.1
+ *
+ * The following table shows the features offered by each SEC version:
+ *
+ * Max. chan-
+ * version Bus I/F Clock nels DEU AESU AFEU MDEU PKEU RNG KEU
+ *
+ * SEC 1.0 internal 64b 100MHz 4 1 1 1 1 1 1 0
+ * SEC 1.2 internal 32b 66MHz 1 1 1 0 1 0 0 0
+ * SEC 2.0 internal 64b 166MHz 4 1 1 1 1 1 1 0
+ * SEC 2.01 internal 64b 166MHz 4 1 1 1 1 1 1 0
+ * SEC 2.1 internal 64b 333MHz 4 1 1 1 1 1 1 1
+ *
+ * Each execution unit in the SEC has two modes of execution; channel and
+ * slave/debug. This driver employs the channel infrastructure in the
+ * device for convenience. Only the RNG is directly accessed due to the
+ * convenience of its random fifo pool. The relationship between the
+ * channels and execution units is depicted in the following diagram:
+ *
+ * ------- ------------
+ * ---| ch0 |---| |
+ * ------- | |
+ * | |------+-------+-------+-------+------------
+ * ------- | | | | | | |
+ * ---| ch1 |---| | | | | | |
+ * ------- | | ------ ------ ------ ------ ------
+ * |controller| |DEU | |AESU| |MDEU| |PKEU| ... |RNG |
+ * ------- | | ------ ------ ------ ------ ------
+ * ---| ch2 |---| | | | | | |
+ * ------- | | | | | | |
+ * | |------+-------+-------+-------+------------
+ * ------- | |
+ * ---| ch3 |---| |
+ * ------- ------------
+ *
+ * Channel ch0 may drive an aes operation to the aes unit (AESU),
+ * and, at the same time, ch1 may drive a message digest operation
+ * to the mdeu. Each channel has an input descriptor FIFO, and the
+ * FIFO can contain, e.g. on the 8541E, up to 24 entries, before a
+ * a buffer overrun error is triggered. The controller is responsible
+ * for fetching the data from descriptor pointers, and passing the
+ * data to the appropriate EUs. The controller also writes the
+ * cryptographic operation's result to memory. The SEC notifies
+ * completion by triggering an interrupt and/or setting the 1st byte
+ * of the hdr field to 0xff.
+ *
+ * TODO:
+ * o support more algorithms
+ * o support more versions of the SEC
+ * o add support for linux 2.4
+ * o scatter-gather (sg) support
+ * o add support for public key ops (PKEU)
+ * o add statistics

+ default n
+ depends on MTD
+ select YAFFS_YAFFS1
+ select YAFFS_YAFFS2
+ help
+ YAFFS2, or Yet Another Flash Filing System, is a filing system
+ optimised for NAND Flash chips.
+
+ To compile the YAFFS2 file system support as a module, choose M
+ here: the module will be called yaffs2.
+
+ If unsure, say N.
+
+ Further information on YAFFS2 is available at
+ <http://www.aleph1.co.uk/yaffs/>.
+
+config YAFFS_YAFFS1
+ bool "512 byte / page devices"
+ depends on YAFFS_FS
+ default y
+ help
+ Enable YAFFS1 support -- yaffs for 512 byte / page devices
+
+ Not needed for 2K-page devices.
+
+ If unsure, say Y.
+
+config YAFFS_9BYTE_TAGS
+ bool "Use older-style on-NAND data format with pageStatus byte"
+ depends on YAFFS_YAFFS1
+ default n
+ help
+
+ Older-style on-NAND data format has a "pageStatus" byte to record
+ chunk/page state. This byte is zero when the page is discarded.
+ Choose this option if you have existing on-NAND data using this
+ format that you need to continue to support. New data written
+ also uses the older-style format. Note: Use of this option
+ generally requires that MTD's oob layout be adjusted to use the
+ older-style format. See notes on tags formats and MTD versions.
+
+ If unsure, say N.
+
+config YAFFS_DOES_ECC
+ bool "Lets Yaffs do its own ECC"
+ depends on YAFFS_FS && YAFFS_YAFFS1 && !YAFFS_9BYTE_TAGS
+ default n
+ help
+ This enables Yaffs to use its own ECC functions instead of using
+ the ones from the generic MTD-NAND driver.
+
+ If unsure, say N.
+
+config YAFFS_ECC_WRONG_ORDER
+ bool "Use the same ecc byte order as Steven Hill's nand_ecc.c"
+ depends on YAFFS_FS && YAFFS_DOES_ECC && !YAFFS_9BYTE_TAGS
+ default n
+ help
+ This makes yaffs_ecc.c use the same ecc byte order as Steven
+ Hill's nand_ecc.c. If not set, then you get the same ecc byte
+ order as SmartMedia.
+
+ If unsure, say N.
+
+config YAFFS_YAFFS2
+ bool "2048 byte (or larger) / page devices"
+ depends on YAFFS_FS
+ default y
+ help
+ Enable YAFFS2 support -- yaffs for >= 2K bytes per page devices
+
+ If unsure, say Y.
+
+config YAFFS_AUTO_YAFFS2
+ bool "Autoselect yaffs2 format"
+ depends on YAFFS_YAFFS2
+ default y
+ help
+ Without this, you need to explicitely use yaffs2 as the file
+ system type. With this, you can say "yaffs" and yaffs or yaffs2
+ will be used depending on the device page size (yaffs on
+ 512-byte page devices, yaffs2 on 2K page devices).
+
+ If unsure, say Y.
+
+config YAFFS_DISABLE_LAZY_LOAD
+ bool "Disable lazy loading"
+ depends on YAFFS_YAFFS2
+ default n
+ help
+ "Lazy loading" defers loading file details until they are
+ required. This saves mount time, but makes the first look-up
+ a bit longer.
+
+ Lazy loading will only happen if enabled by this option being 'n'
+ and if the appropriate tags are available, else yaffs2 will
+ automatically fall back to immediate loading and do the right
+ thing.
+
+ Lazy laoding will be required by checkpointing.
+
+ Setting this to 'y' will disable lazy loading.
+
+ If unsure, say N.
+
+config YAFFS_CHECKPOINT_RESERVED_BLOCKS
+ int "Reserved blocks for checkpointing"
+ depends on YAFFS_YAFFS2
+ default 10
+ help
+ Give the number of Blocks to reserve for checkpointing.
+ Checkpointing saves the state at unmount so that mounting is
+ much faster as a scan of all the flash to regenerate this state
+ is not needed. These Blocks are reserved per partition, so if
+ you have very small partitions the default (10) may be a mess
+ for you. You can set this value to 0, but that does not mean
+ checkpointing is disabled at all. There only won't be any
+ specially reserved blocks for checkpointing, so if there is
+ enough free space on the filesystem, it will be used for
+ checkpointing.
+
+ If unsure, leave at default (10), but don't wonder if there are
+ always 2MB used on your large page device partition (10 x 2k
+ pagesize). When using small partitions or when being very small
+ on space, you probably want to set this to zero.
+
+config YAFFS_DISABLE_WIDE_TNODES
+ bool "Turn off wide tnodes"
+ depends on YAFFS_FS
+ default n
+ help
+ Wide tnodes are only used for NAND arrays >=32MB for 512-byte
+ page devices and >=128MB for 2k page devices. They use slightly
+ more RAM but are faster since they eliminate chunk group
+ searching.
+
+ Setting this to 'y' will force tnode width to 16 bits and save
+ memory but make large arrays slower.
+
+ If unsure, say N.
+
+config YAFFS_ALWAYS_CHECK_CHUNK_ERASED
+ bool "Force chunk erase check"
+ depends on YAFFS_FS
+ default n
+ help
+ Normally YAFFS only checks chunks before writing until an erased
+ chunk is found. This helps to detect any partially written
+ chunks that might have happened due to power loss.
+
+ Enabling this forces on the test that chunks are erased in flash
+ before writing to them. This takes more time but is potentially
+ a bit more secure.
+
+ Suggest setting Y during development and ironing out driver
+ issues etc. Suggest setting to N if you want faster writing.
+
+ If unsure, say Y.
+
+config YAFFS_SHORT_NAMES_IN_RAM
+ bool "Cache short names in RAM"
+ depends on YAFFS_FS
+ default y
+ help
+ If this config is set, then short names are stored with the
+ yaffs_Object. This costs an extra 16 bytes of RAM per object,
+ but makes look-ups faster.
+
+ If unsure, say Y.

+ * This Linux kernel header is expanded from the original driver
+ * (gpio_dev) by John Crispin. It provides an ioctl based interface to
+ * GPIO pins via the /dev/gpio char device and gpiolib within the kernel.
+ * The third argument to each ioctl is the GPIO pin number.
+ *
+ * This driver has been tested with lk 2.6.31 and works. The original
+ * driver fails quietly with this version. The protocol is now a bit
+ * different: the ioctl(fd, GPIO_REQUEST, <pin>) should be called
+ * after the open("/dev/gpio", O_RDWR) to determine if the <pin> is
+ * already in use. If the ioctl is successful (i.e. returns 0 for not
+ * in use) then the <pin> is claimed by this driver and
+ * ioctl(fd, GPIO_FREE, <pin>) should be called prior to close(fd) .
+ *
+ * See <kernel_source>/Documentation/gpio.txt
+ * Note that kernel designers prefer the use of the sysfs gpio interface.
+ * This char driver is easier to use from code and faster.

++ select ZLIB_INFLATE
++ help
++ Saying Y here includes support for SquashFS 3.0 (a Compressed Read-Only File
++ System). Squashfs is a highly compressed read-only filesystem for Linux.
++ It uses zlib compression to compress both files, inodes and directories.
++ Inodes in the system are very small and all blocks are packed to minimise
++ data overhead. Block sizes greater than 4K are supported up to a maximum of 64K.
++ SquashFS 3.0 supports 64 bit filesystems and files (larger than 4GB), full
++ uid/gid information, hard links and timestamps.
++
++ Squashfs is intended for general read-only filesystem use, for archival
++ use (i.e. in cases where a .tar.gz file may be used), and in embedded
++ systems where low overhead is needed. Further information and filesystem tools
++ are available from http://squashfs.sourceforge.net.
++
++ If you want to compile this as a module ( = code which can be
++ inserted in and removed from the running kernel whenever you want),
++ say M here and read <file:Documentation/modules.txt>. The module
++ will be called squashfs. Note that the root file system (the one
++ containing the directory /) cannot be compiled as a module.

++ int "Number of fragments cached" if SQUASHFS_EMBEDDED
++ depends on SQUASHFS
++ default "3"
++ help
++ By default SquashFS caches the last 3 fragments read from
++ the filesystem. Increasing this amount may mean SquashFS
++ has to re-read fragments less often from disk, at the expense
++ of extra system memory. Decreasing this amount will mean
++ SquashFS uses less memory at the expense of extra reads from disk.
++
++ Note there must be at least one cached fragment. Anything
++ much more than three will probably not make much difference.
++
++config SQUASHFS_VMALLOC
++ bool "Use Vmalloc rather than Kmalloc" if SQUASHFS_EMBEDDED
++ depends on SQUASHFS
++ default n
++ help
++ By default SquashFS uses kmalloc to obtain fragment cache memory.
++ Kmalloc memory is the standard kernel allocator, but it can fail
++ on memory constrained systems. Because of the way Vmalloc works,
++ Vmalloc can succeed when kmalloc fails. Specifying this option
++ will make SquashFS always use Vmalloc to allocate the
++ fragment cache memory.

++ * all nodes except BRANCH implement concatenation; a "next" pointer with
++ * a BRANCH on both ends of it is connecting two alternatives. (Here we
++ * have one of the subtle syntax dependencies: an individual BRANCH (as
++ * opposed to a collection of them) is never concatenated with anything
++ * because of operator precedence.) The operand of some types of node is
++ * a literal string; for others, it is a node leading into a sub-FSM. In
++ * particular, the operand of a BRANCH node is the first node of the branch.
++ * (NB this is *not* a tree structure: the tail of the branch connects
++ * to the thing following the set of BRANCHes.) The opcodes are:

+Date: Wed May 21 14:08:38 2008 -0700
+
+ netfilter: Move linux/types.h inclusions outside of #ifdef __KERNEL__
+
+ Greg Steuck <greg@nest.cx> points out that some of the netfilter
+ headers can't be used in userspace without including linux/types.h
+ first. The headers include their own linux/types.h include statements,
+ these are stripped by make headers-install because they are inside
+ #ifdef __KERNEL__ however. Move them out to fix this.
+
+ Reported and Tested by Greg Steuck.

++ *
++ * Authors: Patrick McHardy, <kaber@trash.net>
++ *
++ * The first version was written by Martin Devera, <devik@cdi.cz>
++ *
++ * Credits: Jan Rafaj <imq2t@cedric.vabo.cz>
++ * - Update patch to 2.4.21
++ * Sebastian Strollo <sstrollo@nortelnetworks.com>
++ * - Fix "Dead-loop on netdevice imq"-issue
++ * Marcel Sebek <sebek64@post.cz>
++ * - Update to 2.6.2-rc1
++ *
++ * After some time of inactivity there is a group taking care
++ * of IMQ again: http://www.linuximq.net
++ *
++ *
++ * 2004/06/30 - New version of IMQ patch to kernels <=2.6.7
++ * including the following changes:
++ *
++ * - Correction of ipv6 support "+"s issue (Hasso Tepper)
++ * - Correction of imq_init_devs() issue that resulted in
++ * kernel OOPS unloading IMQ as module (Norbert Buchmuller)
++ * - Addition of functionality to choose number of IMQ devices
++ * during kernel config (Andre Correa)
++ * - Addition of functionality to choose how IMQ hooks on
++ * PRE and POSTROUTING (after or before NAT) (Andre Correa)
++ * - Cosmetic corrections (Norbert Buchmuller) (Andre Correa)
++ *
++ *
++ * 2005/12/16 - IMQ versions between 2.6.7 and 2.6.13 were
++ * released with almost no problems. 2.6.14-x was released
++ * with some important changes: nfcache was removed; After
++ * some weeks of trouble we figured out that some IMQ fields
++ * in skb were missing in skbuff.c - skb_clone and copy_skb_header.
++ * These functions are correctly patched by this new patch version.
++ *
++ * Thanks for all who helped to figure out all the problems with
++ * 2.6.14.x: Patrick McHardy, Rune Kock, VeNoMouS, Max CtRiX,
++ * Kevin Shanahan, Richard Lucassen, Valery Dachev (hopefully
++ * I didn't forget anybody). I apologize again for my lack of time.
++ *
++ *
++ * 2008/06/17 - 2.6.25 - Changed imq.c to use qdisc_run() instead
++ * of qdisc_restart() and moved qdisc_run() to tasklet to avoid
++ * recursive locking. New initialization routines to fix 'rmmod' not
++ * working anymore. Used code from ifb.c. (Jussi Kivilinna)
++ *
++ * Also, many thanks to pablo Sebastian Greco for making the initial
++ * patch and to those who helped the testing.
++ *
++ * More info at: http://www.linuximq.net/ (Andre Correa)

++ This is an enchanced SFQ version which allows you to control some

++
++ ESFQ also adds control of the hash function used to identify packet

++2005-06-30 Eric Lammerts <eric@lammerts.org>

++2005-06-09 <mk@mary>

++
++ * Added mini_fo-merge script to allow merging of storage and base
++ after making modifications.
++
++2005-05-22 root <mk@mary>
++
++ * Added overlay script that allows to easily mount mini_fo ontop
++ of a given base directory
++
++2005-05-10 <mk@mary>
++
++ * inode.c: xattr functions return -EOPNOSUPP instead of
++ -ENOSUPP, what confuses "ls -l"
++
++ * Changed license from LGPL to GPL.
++
++2005-05-08 root <mk@mary>
++
++ * Makefile: clean it up and added make install and make
++ uninstall.
++
++2005-05-06 <mk@mary>
++
++ * merged devel branch back to main. [v0-6-0-pre3]
++
++ * removed unused files print.c and fist_ioctl. [devel-0-0-18]
++
++ * ioctl: removed fist_ioctl stuff, that is not needed for
++ now.
++
++2005-05-03 <mk@mary>
++
++ * file.c: simplified mini_fo_open and mini_fo_setattr using
++ new state changing functions. [devel-0-0-17]
++
++ * inode.c: Fixed getattr state bug (see below) in 2.4 function
++ mini_fo_inode revalidate.
++
++ * inode.c: found an other bug in mini_fo_getattr. States are not
++ reliable in this function, as a file can be opened, unlinked and
++ the getattr function called. This results in a deleted dentry
++ with an inode. Fix is to ignore states and simply use the inode
++ available.
++
++2005-04-29 <mk@mary>
++
++ * file.c: Bugfix and cleanup in fasync and fsync. [devel-0-0-16]
++
++ * file.c: do not use mini_fo_lock so the generic version is
++ used (I guess).
++
++ * inode.c: getattr, never call getattr on lower files, as this
++ will cause the inum to change.
++
++ * inode.c: rename_reg_file renamed to rename_nondir, as it
++ doesn't matter as long it't not a dir. Removed all
++ rename_dev_file etc.
++
++ * tagged as devel-0-0-15
++
++ * inode.c: added support for chosing support for extended
++ attrs at compile time by XATTR define in mini_fo.h .
++
++ * inode.c: fixed mini_fo_getattr to use mini_fo inode and not
++ lower again, what avoids inode number changes that confused
++ rm again. This is the proper solution.
++
++2005-04-24 <mk@mary>
++
++ * all files: updated Copyright notive to 2005. [devel-0-0-14]
++
++ * inode.c: fixed mini_fo_getattr to not change the inode
++ number, even if lower files change.
++
++ * super.c: fixed a bug that caused deleted base file to show
++ up suddenly after some time, or after creating a special
++ file. The problem was that after some time or after special
++ file creating sync_sb_inodes is called by the vfs, that
++ called our mini_fo_put_inode. There was (wrongly) called
++ __meta_put_lists, that nuked the lists, although the inode
++ was going to continue its life. Moving __meta_put_lists to
++ mini_fo_clear_inode, where an inode is really destroyed,
++ solved the problem.
++
++
++2005-04-23 <mk@mary>
++
++ * state.c, aux.c: more cleaning up and
++ simplifications. [devel-0-0-13]
++
++ * inode.c: implemented mini_fo_getattr, that was required for
++ 2.6 because inode_revalidate has been remove there, and the
++ old "du" bug returned.
++
++
++2005-04-20 <mk@mary>
++
++ * aux.c: get_neg_sto_dentry(): allow to be called for dentries
++ in state UNMODIFIED, NON_EXISTANT _and_ DELETED.
++
++2005-04-19 <mk@mary>
++
++ * Fixed a bug under 2.6 that caused files deleted via mini_fo
++ not to be deleted properly and therefore the fs filled up
++ untill no memory was left. [devel-0-0-12]
++
++ * Added basic hard link support. This means that creating
++ hardlinks will work, but existing ones will be treated as
++ individual files. [devel-0-0-11]
++
++2005-04-17 <mk@mary>
++
++ * Bugfixes
++
++2005-04-13 root <mk@mary>
++
++ * Added file state.c for the state transition
++ functions. Doesn't work very well yet, though...
++
++2005-04-12 <mk@mary>
++
++ * Porting to 2.6 started, which is easier than expected, also
++ due to Olivier previous work.
++
++2005-04-08 <mk@mary>
++
++ * Fixed the bug that caused du to return invalid sizes of
++ directory trees. The problem was that
++ mini_fo_inode_revalidate didn't always copy the attributes
++ from the base inode properly.
++
++2005-04-01 Markus Klotzbuecher <mk@chasey>
++
++ * Merged devel branch back to main trunk and updated the
++ RELEASE notes. This will be 0-6-0-pre1.
++
++2005-03-31 Markus Klotzbuecher <mk@chasey>
++
++ * Fixed some bugs in rename_reg_file, that only showed up in
++ the kernel compile test. Kernel compiles cleanly ontop of
++ mini_fo, now also make mrproper etc. work. Seems pretty stable.
++
++2005-03-28 Markus Klotzbuecher <mk@chasey>
++
++ * Many, many directory renaming bugfixes and a lot of other
++ cleanup. Dir renaming seems to work relatively stable.
++
++2005-03-22 Markus Klotzbuecher <mk@chasey>
++
++ * Finished implementing lightweight directory renaming. Some
++ basic testing indicates it works fine.
++ Next is to implement testcases for the testsuite and confirm
++ everything is really working ok.
++
++2005-03-18 Markus Klotzbuecher <mk@chasey>
++
++ * Finished implementing meta.c stuff required for directory
++ renaming.
++
++2005-03-17 Markus Klotzbuecher <mk@chasey>
++
++ * Fixed all compile warnings + an extremly old bug that
++ somehow crept in while reworking the wol stuff to the META
++ system. Turning on -Werror again... :-)
++
++ * Fixed some bugs in the new rename_reg_file function.
++
++ * Rewrote mini_fo rename and split it into several
++ subfunctions, that handle the different types
++ seperately. Rewrote the regular file function aswell, as it
++ was implemented somewhat inefficient.
++
++2005-03-16 Markus Klotzbuecher <mk@chasey>
++
++ * Implemented new META subsystem, removed old WOL stuff in favor
++ if it.
++
++ * After some basic testing everything seems ok...
++
++2005-03-11 Markus Klotzbuecher <mk@chasey>
++
++ * Renaming a non regular file caused trouble because I always
++ tried to copy the contents. Now I only do this for regular
++ files. mini_fo_rename still isn't implemented properly, renaming
++ of device files, symlinks etc. results in a empty regular file
++ instead of the proper type.
++
++ * Directory renaming suddenly works! What a surprise! I guess
++ this is because renaming is implemented as making a copy and
++ removing the original. Still this might not work
++ everywhere...
++
++2005-03-09 Markus Klotzbuecher <mk@chasey>
++
++ * Bugfix, when a mini_fo directory that exists in storage
++ (state: MODIFIED, CREATED and DEL_REWRITTEN) is deleted, a
++ possibly existing WOL file contained in it needs to be
++ deleted too.
++
++ * Starting cleanup: defined state names in order to get rid of
++ the state numbers.
++
++2005-03-08 Markus Klotzbuecher <mk@chasey>
++
++ * Makefile fix, fist_ioctl was built against wrong sources if ARCH=um
++
++ * Fixed a bug in dentry.c, mini_fo_d_hash. In state 4 =
++ DEL_REWRITTEN the hash was calculated from the base dentry,
++ which was wrong and and caused assertions in
++ __mini_fo_hidden_dentry to fail.
++
++2005-02-21 <mk@mary>
++
++ * Implemented directory deleting (inode.c)
++
++ * main.c: made mini_fo_parse_options a little more robust.
++
++2004-12-22 <mk@mary>
++
++ * Makefile cleanup and uml stuff, removed unneccessary files
++
++ * Created a new and hopefully more informative README
++
++ * CHANGELOG: created a new CHANGELOG and added old entries reversely
++
++
++2004-10-24 Gleb Natapov <gleb@nbase.co.il>
++
++ * Fix: owner and group where not correctly copied from base to
++ storage.
++
++
++2004-10-05 Gleb Natapov <gleb@nbase.co.il>
++
++ * Implementation of fsync, fasync and lock mini_fo functions.
++
++
++2004-09-29 Bob Lee <bob@pantasys.com>
++
++ * Fix of a serious pointer bug
++
++
++2004-09-28 Gleb Natapov <gleb@nbase.co.il>
++
++ * Implementation of mini_fo_mknod and mini_fo_rename, support
++ for device files.

++Usage: $0 [-s suffix] [-d sto_dir_dir] [-m mount point] base_dir
++Version 0.1
++
++This script overlays the given base directory using the mini_fo file
++system. If only the base directory base_dir is given, $0
++will use a storage directory called "sto-<base_dir_name>" in $STO_DIR,
++and mount point "mini_fo-<base_dir_dir>" in $MNT_DIR.
++
++Options:
++ -s <suffix>
++ add given suffix to storage directory and the mount
++ point. This is usefull for overlaying one base directory
++ several times and avoiding conflicts with storage directory
++ names and mount points.
++
++ -d <sto_dir_dir>
++ change the directory in which the storage directory will be
++ created (default is currently "$STO_DIR".
++
++ -m <mount point>
++ use an alternative directory to create the mini_fo
++ mountpoint (default is currently "$MNT_DIR".
++
++ -h displays this message.

++README for the mini_fo overlay file system
++=========================================
++
++
++WHAT IS MINI_FO?
++----------------
++
++mini_fo is a virtual kernel file system that can make read-only
++file systems writable. This is done by redirecting modifying operations
++to a writeable location called "storage directory", and leaving the
++original data in the "base directory" untouched. When reading, the
++file system merges the modifed and original data so that only the
++newest versions will appear. This occurs transparently to the user,
++who can access the data like on any other read-write file system.
++
++Base and storage directories may be located on the same or on
++different partitions and may be of different file system types. While
++the storage directory obviously needs to be writable, the base may or
++may not be writable, what doesn't matter as it will no be modified
++anyway.
++
++
++WHAT IS GOOD FOR?
++-----------------
++
++The primary purpose of the mini_fo file system is to allow easy
++software updates to embedded systems, that often store their root
++file system in a read-only flash file system, but there are many
++more as for example sandboxing, or for allowing live-cds to
++permanently store information.
++
++
++BUILDING
++--------
++This should be simple. Adjust the Makefile to point to the correct
++kernel headers you want to build the module for. Then:
++
++ # make
++
++should build "mini_fo.o" for a 2.4 kernel or "mini_fo.ko" for a 2.6
++kernel.
++
++If you are building the module for you current kernel, you can install
++the module (as root):
++
++ # make install
++
++or uninstall with
++
++ # make uninstall
++
++
++USING THE FILE SYSTEM
++--------------------
++
++the general mount syntax is:
++
++ mount -t mini_fo -o base=<base directory>,sto=<storage directory>\
++ <base directory> <mount point>
++
++Example:
++
++You have mounted a cdrom to /mnt/cdrom and want to modifiy some files
++on it:
++
++load the module (as root)
++
++ # insmod mini_fo.o for a 2.4 kernel or
++
++ # insmod mini_fo.ko for a 2.6 kernel
++
++
++create a storage dir in tmp and a mountpoint for mini_fo:
++
++ # mkdir /tmp/sto
++ # mkdir /mnt/mini_fo
++
++and mount the mini_fo file system:
++
++ # mount -t mini_fo -o base=/mnt/cdrom,sto=/tmp/sto /mnt/cdrom /mnt/mini_fo
++
++
++Now the data stored on the cd can be accessed via the mini_fo
++mountpoint just like any read-write file system, files can be modified
++and deleted, new ones can be created and so on. When done unmount the
++file system:
++
++ # unmount /mnt/mini_fo
++
++Note that if the file system is mounted again using the same storage
++file system, of course it will appear in the modified state again. If
++you remount it using an new empty storage directory, it will be
++unmodified. Therefore by executing:
++
++ # cd /tmp/sto
++ # rm -rf *
++
++you can nuke all the changes you made to the original file system. But
++ remember NEVER do this while the mini_fo file system is mounted!
++
++
++Alternatively you can use the mini_fo-overlay bash script, that
++simplifies managing mini_fo mounts. See TOOLS Section.
++
++
++TOOLS
++-----
++
++mini_fo-merge (experimental):
++
++This is a bash script that will merge changes contained in the storage
++directory back to the base directory. This allows mini_fo to function
++as a cache file system by overlaying a slow (network, ...) file system
++and using a fast (ramdisk, ...) as storage. When done, changes can be
++merged back to the (slow) base with mini_fo-merge. See "mini_fo-merge
++-h" for details.
++
++It can be usefull for merging changes back after a successfull test
++(patches, software updates...)
++
++
++mini_fo-overlay:
++
++This bash script simplifies managing one or more mini_fo mounts. For
++overlaying a directory called "basedir1", you can just call:
++
++ # mini_fo-overlay basedir1
++
++This will mount mini_fo with "basedir1" as base, "/tmp/sto-basedir1/"
++as storage to "/mnt/mini_fo-basedir1/". It has more options though,
++type "mini_fo-overlay -h" for details.
++
++
++DOCUMENTATION, REPORTING BUGS, GETTING HELP
++-------------------------------------------
++
++Please visit the mini_fo project page at:
++
++http://www.denx.de/twiki/bin/view/Know/MiniFOHome
++
++
++WARNINGS
++--------
++
++Never modify the base or the storage directorys while the mini_fo
++file system is mounted, or you might crash you system. Simply accessing
++and reading should not cause any trouble.
++
++Exporting a mini_fo mount point via NFS has not been tested, and may
++or may not work.
++
++Check the RELEASE_NOTES for details on bugs and features.

++Release: mini_fo-0.6.1 (v0-6-1)
++Date: 21.09.2005
++
++
++Changes:
++--------
++v0-6-1:
++
++- bugfixes (see ChangeLog)
++
++- two helper scripts "mini_fo_merge" and "mini_fo_overlay" (see
++ README for details).
++
++v0-6-0:
++
++- Support for 2.4 and 2.6 (see Makefile)
++
++- Partial hard link support (creating works as expected, but already
++ existing links in the base file system will be treated as if they
++ were individual files).
++
++- Various bugfixes and cleanups.
++
++
++v0-6-0-pre1:
++
++- This is mini_fo-0-6-0-pre1! This release is a complete rewrite of
++ many vital mini_fo parts such as the old whiteout list code which
++ has been replaced by the new META subsystem.
++
++- Light weight directory renaming implemented. This means if a
++ directory is renamed via the mini_fo filesystem this will no longer
++ result in a complete copy in storage, instead only one empty
++ directory will be created. All base filed contained in the original
++ directory stay there until modified.
++
++- Special files (creating, renaming, deleting etc.) now working.
++
++- Many bugfixes and cleanup, mini_fo is now a lot more stable.
++
++
++v0-5-10:
++
++- Final release of the 0-5-* versions. Next will be a complete rewrite
++ of many features. This release contains several bugfixes related to
++ directory renaming.
++
++
++v0-5-10-pre6:
++
++- Lots of cleanup and several bugfixes related to directory deleting
++
++- Directory renaming suddenly works, what is most likely due to the
++ fact tha that "mv" is smart: if the classic rename doesn't work it
++ will assume that source and target file are on different fs and will
++ copy the directory and try to remove the source directory. Until
++ directory removing wasn't implemented, it would fail to do this and
++ rollback.
++ So, directory renaming works for now, but it doesn't yet do what you
++ would expect from a overlay fs, so use with care.
++
++
++v0-5-10-pre5:
++
++- implemented directory deleting
++- made parsing of mount options more stable
++- New format of mount options! (See README)
++- I can't reproduce the unknown panic with 2.4.25 anymore, so I'll
++ happily assume it never existed!
++
++
++Implemented features:
++---------------------
++
++- creating hard links (see BUGS on already existing hard links)
++- lightweight directory renaming
++- renaming device files, pipes, sockets, etc.
++- creating, renaming, deleting of special files
++- deleting directorys
++- general directory reading (simple "ls" )
++- creating files in existing directorys
++- creating directorys
++- renaming files.
++- reading and writing files (involves opening)
++- appending to files (creates copy in storage)
++- deleting files
++- llseek works too, what allows editors to work
++- persistency (a deleted file stay deleted over remounts)
++- use of symbolic links
++- creating of device files
++
++
++Not (yet) implemented features:
++-------------------------------
++
++- full hard link support.
++
++
++
++BUGS:
++-----
++
++Hard links in the base file system will be treated as individual
++files, not as links to one inode.
++
++The main problem with hard links isn't allowing to create them, but
++their pure existence. If you modify a base hard link, the changes made
++will only show up on this link, the other link will remain in the
++original state. I hope to fix this someday. Please note that this does
++not effect the special hard links '.' and '..', that are handled
++seperately by the lower fs.

++VII - Marvell Discovery mv64[345]6x System Controller chips
++===========================================================
++
++The Marvell mv64[345]60 series of system controller chips contain
++many of the peripherals needed to implement a complete computer
++system. In this section, we define device tree nodes to describe
++the system controller chip itself and each of the peripherals
++which it contains. Compatible string values for each node are
++prefixed with the string "marvell,", for Marvell Technology Group Ltd.
++
++1) The /system-controller node
++
++ This node is used to represent the system-controller and must be
++ present when the system uses a system contller chip. The top-level
++ system-controller node contains information that is global to all
++ devices within the system controller chip. The node name begins
++ with "system-controller" followed by the unit address, which is
++ the base address of the memory-mapped register set for the system
++ controller chip.
++
++ Required properties:
++
++ - ranges : Describes the translation of system controller addresses
++ for memory mapped registers.
++ - clock-frequency: Contains the main clock frequency for the system
++ controller chip.
++ - reg : This property defines the address and size of the
++ memory-mapped registers contained within the system controller
++ chip. The address specified in the "reg" property should match
++ the unit address of the system-controller node.
++ - #address-cells : Address representation for system controller
++ devices. This field represents the number of cells needed to
++ represent the address of the memory-mapped registers of devices
++ within the system controller chip.
++ - #size-cells : Size representation for for the memory-mapped
++ registers within the system controller chip.
++ - #interrupt-cells : Defines the width of cells used to represent
++ interrupts.
++
++ Optional properties:
++
++ - model : The specific model of the system controller chip. Such
++ as, "mv64360", "mv64460", or "mv64560".
++ - compatible : A string identifying the compatibility identifiers
++ of the system controller chip.
++
++ The system-controller node contains child nodes for each system
++ controller device that the platform uses. Nodes should not be created
++ for devices which exist on the system controller chip but are not used
++
++ Example Marvell Discovery mv64360 system-controller node:
++
++ system-controller@f1000000 { /* Marvell Discovery mv64360 */
++ #address-cells = <1>;
++ #size-cells = <1>;
++ model = "mv64360"; /* Default */
++ compatible = "marvell,mv64360";
++ clock-frequency = <133333333>;
++ reg = <0xf1000000 0x10000>;
++ virtual-reg = <0xf1000000>;
++ ranges = <0x88000000 0x88000000 0x1000000 /* PCI 0 I/O Space */
++ 0x80000000 0x80000000 0x8000000 /* PCI 0 MEM Space */
++ 0xa0000000 0xa0000000 0x4000000 /* User FLASH */
++ 0x00000000 0xf1000000 0x0010000 /* Bridge's regs */
++ 0xf2000000 0xf2000000 0x0040000>;/* Integrated SRAM */
++
++ [ child node definitions... ]
++ }
++
++2) Child nodes of /system-controller
++
++ a) Marvell Discovery MDIO bus
++
++ The MDIO is a bus to which the PHY devices are connected. For each
++ device that exists on this bus, a child node should be created. See
++ the definition of the PHY node below for an example of how to define
++ a PHY.
++
++ Required properties:
++ - #address-cells : Should be <1>
++ - #size-cells : Should be <0>
++ - device_type : Should be "mdio"
++ - compatible : Should be "marvell,mv64360-mdio"
++
++ Example:
++
++ mdio {
++ #address-cells = <1>;
++ #size-cells = <0>;
++ device_type = "mdio";
++ compatible = "marvell,mv64360-mdio";
++
++ ethernet-phy@0 {
++ ......
++ };
++ };
++
++
++ b) Marvell Discovery ethernet controller
++
++ The Discover ethernet controller is described with two levels
++ of nodes. The first level describes an ethernet silicon block
++ and the second level describes up to 3 ethernet nodes within
++ that block. The reason for the multiple levels is that the
++ registers for the node are interleaved within a single set
++ of registers. The "ethernet-block" level describes the
++ shared register set, and the "ethernet" nodes describe ethernet
++ port-specific properties.

++ Hypervisor-Assisted Dump
++ ------------------------
++ November 2007
++
++The goal of hypervisor-assisted dump is to enable the dump of
++a crashed system, and to do so from a fully-reset system, and
++to minimize the total elapsed time until the system is back
++in production use.
++
++As compared to kdump or other strategies, hypervisor-assisted
++dump offers several strong, practical advantages:
++
++-- Unlike kdump, the system has been reset, and loaded
++ with a fresh copy of the kernel. In particular,
++ PCI and I/O devices have been reinitialized and are
++ in a clean, consistent state.
++-- As the dump is performed, the dumped memory becomes
++ immediately available to the system for normal use.
++-- After the dump is completed, no further reboots are
++ required; the system will be fully usable, and running
++ in it's normal, production mode on it normal kernel.
++
++The above can only be accomplished by coordination with,
++and assistance from the hypervisor. The procedure is
++as follows:
++
++-- When a system crashes, the hypervisor will save
++ the low 256MB of RAM to a previously registered
++ save region. It will also save system state, system
++ registers, and hardware PTE's.
++
++-- After the low 256MB area has been saved, the
++ hypervisor will reset PCI and other hardware state.
++ It will *not* clear RAM. It will then launch the
++ bootloader, as normal.
++
++-- The freshly booted kernel will notice that there
++ is a new node (ibm,dump-kernel) in the device tree,
++ indicating that there is crash data available from
++ a previous boot. It will boot into only 256MB of RAM,
++ reserving the rest of system memory.
++
++-- Userspace tools will parse /sys/kernel/release_region
++ and read /proc/vmcore to obtain the contents of memory,
++ which holds the previous crashed kernel. The userspace
++ tools may copy this info to disk, or network, nas, san,
++ iscsi, etc. as desired.
++
++ For Example: the values in /sys/kernel/release-region
++ would look something like this (address-range pairs).
++ CPU:0x177fee000-0x10000: HPTE:0x177ffe020-0x1000: /
++ DUMP:0x177fff020-0x10000000, 0x10000000-0x16F1D370A
++
++-- As the userspace tools complete saving a portion of
++ dump, they echo an offset and size to
++ /sys/kernel/release_region to release the reserved
++ memory back to general use.
++
++ An example of this is:
++ "echo 0x40000000 0x10000000 > /sys/kernel/release_region"
++ which will release 256MB at the 1GB boundary.
++
++Please note that the hypervisor-assisted dump feature
++is only available on Power6-based systems with recent
++firmware versions.
++
++Implementation details:
++----------------------
++
++During boot, a check is made to see if firmware supports
++this feature on this particular machine. If it does, then
++we check to see if a active dump is waiting for us. If yes
++then everything but 256 MB of RAM is reserved during early
++boot. This area is released once we collect a dump from user
++land scripts that are run. If there is dump data, then
++the /sys/kernel/release_region file is created, and
++the reserved memory is held.
++
++If there is no waiting dump data, then only the highest
++256MB of the ram is reserved as a scratch area. This area
++is *not* released: this region will be kept permanently
++reserved, so that it can act as a receptacle for a copy
++of the low 256MB in the case a crash does occur. See,
++however, "open issues" below, as to whether
++such a reserved region is really needed.
++
++Currently the dump will be copied from /proc/vmcore to a
++a new file upon user intervention. The starting address
++to be read and the range for each data point in provided
++in /sys/kernel/release_region.
++
++The tools to examine the dump will be same as the ones
++used for kdump.
++
++General notes:
++--------------
++Security: please note that there are potential security issues
++with any sort of dump mechanism. In particular, plaintext
++(unencrypted) data, and possibly passwords, may be present in
++the dump data. Userspace tools must take adequate precautions to
++preserve security.
++
++Open issues/ToDo:
++------------
++ o The various code paths that tell the hypervisor that a crash
++ occurred, vs. it simply being a normal reboot, should be
++ reviewed, and possibly clarified/fixed.
++
++ o Instead of using /sys/kernel, should there be a /sys/dump
++ instead? There is a dump_subsys being created by the s390 code,
++ perhaps the pseries code should use a similar layout as well.
++
++ o Is reserving a 256MB region really required? The goal of
++ reserving a 256MB scratch area is to make sure that no
++ important crash data is clobbered when the hypervisor
++ save low mem to the scratch area. But, if one could assure
++ that nothing important is located in some 256MB area, then
++ it would not need to be reserved. Something that can be
++ improved in subsequent versions.
++
++ o Still working the kdump team to integrate this with kdump,
++ some work remains but this would not affect the current
++ patches.
++
++ o Still need to write a shell script, to copy the dump away.
++ Currently I am parsing it manually.

++GPIOMMC - Driver for an MMC/SD card on a bitbanging GPIO SPI bus
++================================================================
++
++The gpiommc module hooks up the mmc_spi and spi_gpio modules for running an
++MMC or SD card on GPIO pins.
++
++Two interfaces for registering a new MMC/SD card device are provided:
++A static platform-device based mechanism and a dynamic configfs based interface.
++
++
++Registering devices via platform-device
++=======================================
++
++The platform-device interface is used for registering MMC/SD devices that are
++part of the hardware platform. This is most useful only for embedded machines
++with MMC/SD devices statically connected to the platform GPIO bus.
++
++The data structures are declared in <linux/mmc/gpiommc.h>.
++
++To register a new device, define an instance of struct gpiommc_platform_data.
++This structure holds any information about how the device is hooked up to the
++GPIO pins and what hardware modes the device supports. See the docbook-style
++documentation in the header file for more information on the struct fields.
++
++Then allocate a new instance of a platform device by doing:
++
++ pdev = platform_device_alloc(GPIOMMC_PLATDEV_NAME, gpiommc_next_id());
++
++This will allocate the platform device data structures and hook it up to the
++gpiommc driver.
++Then add the gpiommc_platform_data to the platform device.
++
++ err = platform_device_add_data(pdev, pdata, sizeof(struct gpiommc_platform_data));
++
++You may free the local instance of struct gpiommc_platform_data now. (So the
++struct may be allocated on the stack, too).
++Now simply register the platform device.
++
++ err = platform_device_add(pdev);
++
++Done. The gpiommc probe routine will be invoked now and you should see a kernel
++log message for the added device.
++
++
++Registering devices via configfs
++================================
++
++MMC/SD cards connected via GPIO often are a pretty dynamic thing, as for example
++selfmade hacks for soldering an MMC/SD card to standard GPIO pins on embedded
++hardware are a common situation.
++So we provide a dynamic interface to conveniently handle adding and removing
++devices from userspace, without the need to recompile the kernel.
++
++The "gpiommc" subdirectory at the configfs mountpoint is used for handling
++the dynamic configuration.
++
++To create a new device, it must first be allocated with mkdir.
++The following command will allocate a device named "my_mmc":
++ mkdir /config/gpiommc/my_mmc
++
++There are several configuration files available in the new
++/config/gpiommc/my_mmc/ directory:
++
++gpio_data_in = The SPI data-IN GPIO pin number.
++gpio_data_out = The SPI data-OUT GPIO pin number.
++gpio_clock = The SPI Clock GPIO pin number.
++gpio_chipselect = The SPI Chipselect GPIO pin number.
++gpio_chipselect_activelow = Boolean. If 0, Chipselect is active-HIGH.
++ If 1, Chipselect is active-LOW.
++spi_mode = The SPI data mode. Can be 0-3.
++spi_delay = Enable all delays in the lowlevel bitbanging.
++max_bus_speed = The maximum SPI bus speed. In Hertz.
++
++register = Not a configuration parameter.
++ Used to register the configured card
++ with the kernel.
++
++The device must first get configured and then registered by writing "1" to
++the "register" file.
++The configuration parameters "gpio_data_in", "gpio_data_out", "gpio_clock"
++and "gpio_chipselect" are essential and _must_ be configured before writing
++"1" to the "register" file. The registration will fail, otherwise.
++
++The default values for the other parameters are:
++gpio_chipselect_activelow = 1 (CS active-LOW)
++spi_mode = 0 (SPI_MODE_0)
++spi_delay = 1 (enabled)
++max_bus_speed = 5000000 (5 Mhz)
++
++Configuration values can not be changed after registration. To unregister
++the device, write a "0" to the "register" file. The configuration can be
++changed again after unregistering.
++
++To completely remove the device, simply rmdir the directory
++(/config/gpiommc/my_mmc in this example).
++There's no need to first unregister the device before removing it. That will
++be done automatically.

+Paulus,
+
+A similar patch for ppc64 made it upstream with your big ppc64 merge.
+This one is still sitting in http://patchwork.ozlabs.org/linuxppc/
+and didn't make it with the ppc32 equivalent. Thanks.

+gpiolib: better rmmod infrastructure
+
+As long as one or more GPIOs on a gpio chip are used its driver should not be
+unloaded. The existing mechanism (gpiochip_remove failure) doesn't address
+that, since rmmod can no longer be made to fail by having the cleanup code
+report errors. Module usecounts are the solution.
+
+Assuming standard "initialize struct to zero" policies, this change won't
+affect SOC platform drivers. However, drivers for external chips (on I2C and
+SPI busses) should be updated if they can be built as modules.

+gpiolib: dynamic gpio number allocation
+
+If gpio_chip->base is negative during registration, gpiolib performs dynamic
+base allocation. This is useful for devices that aren't always present, such
+as GPIOs on hotplugged devices rather than mainboards. (This behavior was
+previously specified but not implemented.)
+
+To avoid using any numbers that may have been explicitly assigned but not yet
+registered, this dynamic allocation assigns GPIO numbers from the biggest
+number on down, instead of from the smallest on up.

+Subject: [PATCH] bzip2/lzma: remove nasty uncompressed size hack in pre-boot environment
+
+decompress_bunzip2 and decompress_unlzma have a nasty hack that subtracts
+4 from the input length if being called in the pre-boot environment.
+
+This is a nasty hack because it relies on the fact that flush = NULL only
+when called from the pre-boot environment (i.e.
+arch/x86/boot/compressed/misc.c). initramfs.c/do_mounts_rd.c pass in a
+flush buffer (flush != NULL).
+
+This hack prevents the decompressors from being used with flush = NULL by
+other callers unless knowledge of the hack is propagated to them.
+
+This patch removes the hack by making decompress (called only from the
+pre-boot environment) a wrapper function that subtracts 4 from the input
+length before calling the decompressor.

+Subject: [PATCH] Squashfs: Make unlzma available to non initramfs/initrd code
+
+Add a config option DECOMPRESS_LZMA_NEEDED which allows subsystems to
+specify they need the unlzma code. Normally decompress_unlzma.c is
+compiled with __init and unlzma is not exported to modules.

+Subject: [PATCH] MIPS: fix loading of modules with unresolved weak symbols
+
+Loading of modules with unresolved weak symbols fails on MIPS
+since '88173507e4fc1e7ecd111b0565e8cba0cb7dae6d'.
+
+Modules: handle symbols that have a zero value
+
+The module subsystem cannot handle symbols that are zero. If symbols
+are present that have a zero value then the module resolver prints out a
+message that these symbols are unresolved.
+
+We have to use IS_ERR_VALUE() to check that a symbol has been resolved
+or not.

+This patch updates kernel part of kexec for MIPS platform to support
+kdump, 64-bit, SMP and simplify code adaptation to new boards. It does
+the following:
+
+- hooks for machine-specific actions are introduced
+(_machine_kexec_prepare,
+ _machine_kexec_shutdown, _machine_crash_shutdown);
+- kexec reboot on SMP machine is implemented;
+- add boot parameters passing to new kernel (array kexec_args[] is
+copied to
+ registers a0-a3 on reboot );
+- crash dump functionality is added (boot kernel with non-default physical
+ start, parse "crashkernel=..." command line parameter, copy_oldmem_page()
+ is implemeted to read memory dump after reboot-on-crashi,
+crash_setup_regs()
+ is updated to correctly store registers on crash);
+
+kexec/kdump funtionality was tested on several Cavium Octeon boards
+(mips64 SMP). The way we do it was the following:
+- _machine_kexec_prepare was find kexec segment with command line and
+save it's pointed into internal bootloader structure.
+- _machine_kexec_shutdown was used to stop boards IO and make all non-boot
+CPUs spin in function relocated_kexec_smp_wait()
+- _machine_crash_shutdown just calls default_machine_crash_shutdown()
+We tested 1) 'common' kexec reboot (by 'kexec -e'), 2) kexec-on-panic
+('kexec -p ...') and 3) access to/proc/vmcore (with gdb).

+GCC 4.4.x looks to be adding support for generating out-of-line register
+saves/restores based on:
+
+http://gcc.gnu.org/ml/gcc-patches/2008-04/msg01678.html
+
+This breaks the kernel build as we'd have to link with libgcc to get the
+implementation of the register save/restores.
+
+To workaround this issue, we just stole the save/restore code from gcc
+and simplified it down for our needs (integer only). We only do this if
+PPC32 as gcc makes believe the linker on ppc64 will deal with this and
+only if CONFIG_CC_OPTIMIZE_FOR_SIZE is set (thus -Os).
+
+Signed-off-by: Kumar Gala <[EMAIL PROTECTED]>
+---
+
+If someone using cutting edge toolchains for ppc64 could test and make
+sure if we enable CONFIG_CC_OPTIMIZE_FOR_SIZE things work that would be
+nice.

++ * Authors: Patrick McHardy, <kaber@trash.net>
++ *
++ * The first version was written by Martin Devera, <devik@cdi.cz>
++ *
++ * Credits: Jan Rafaj <imq2t@cedric.vabo.cz>
++ * - Update patch to 2.4.21
++ * Sebastian Strollo <sstrollo@nortelnetworks.com>
++ * - Fix "Dead-loop on netdevice imq"-issue
++ * Marcel Sebek <sebek64@post.cz>
++ * - Update to 2.6.2-rc1
++ *
++ * After some time of inactivity there is a group taking care
++ * of IMQ again: http://www.linuximq.net
++ *
++ *
++ * 2004/06/30 - New version of IMQ patch to kernels <=2.6.7
++ * including the following changes:
++ *
++ * - Correction of ipv6 support "+"s issue (Hasso Tepper)
++ * - Correction of imq_init_devs() issue that resulted in
++ * kernel OOPS unloading IMQ as module (Norbert Buchmuller)
++ * - Addition of functionality to choose number of IMQ devices
++ * during kernel config (Andre Correa)
++ * - Addition of functionality to choose how IMQ hooks on
++ * PRE and POSTROUTING (after or before NAT) (Andre Correa)
++ * - Cosmetic corrections (Norbert Buchmuller) (Andre Correa)
++ *
++ *
++ * 2005/12/16 - IMQ versions between 2.6.7 and 2.6.13 were
++ * released with almost no problems. 2.6.14-x was released
++ * with some important changes: nfcache was removed; After
++ * some weeks of trouble we figured out that some IMQ fields
++ * in skb were missing in skbuff.c - skb_clone and copy_skb_header.
++ * These functions are correctly patched by this new patch version.
++ *
++ * Thanks for all who helped to figure out all the problems with
++ * 2.6.14.x: Patrick McHardy, Rune Kock, VeNoMouS, Max CtRiX,
++ * Kevin Shanahan, Richard Lucassen, Valery Dachev (hopefully
++ * I didn't forget anybody). I apologize again for my lack of time.
++ *
++ *
++ * 2008/06/17 - 2.6.25 - Changed imq.c to use qdisc_run() instead
++ * of qdisc_restart() and moved qdisc_run() to tasklet to avoid
++ * recursive locking. New initialization routines to fix 'rmmod' not
++ * working anymore. Used code from ifb.c. (Jussi Kivilinna)
++ *
++ * 2008/08/06 - 2.6.26 - (JK)
++ * - Replaced tasklet with 'netif_schedule()'.
++ * - Cleaned up and added comments for imq_nf_queue().
++ *
++ * 2009/04/12
++ * - Add skb_save_cb/skb_restore_cb helper functions for backuping
++ * control buffer. This is needed because qdisc-layer on kernels
++ * 2.6.27 and newer overwrite control buffer. (Jussi Kivilinna)
++ * - Add better locking for IMQ device. Hopefully this will solve
++ * SMP issues. (Jussi Kivilinna)
++ * - Port to 2.6.27
++ * - Port to 2.6.28
++ * - Port to 2.6.29 + fix rmmod not working
++ *
++ * 2009/04/20 - (Jussi Kivilinna)
++ * - Use netdevice feature flags to avoid extra packet handling
++ * by core networking layer and possibly increase performance.
++ *
++ * Also, many thanks to pablo Sebastian Greco for making the initial
++ * patch and to those who helped the testing.
++ *
++ * More info at: http://www.linuximq.net/ (Andre Correa)

++
++ * Changed license from LGPL to GPL.
++
++2005-05-08 root <mk@mary>
++
++ * Makefile: clean it up and added make install and make

++
++2005-05-06 <mk@mary>
++
++ * merged devel branch back to main. [v0-6-0-pre3]
++
++ * removed unused files print.c and fist_ioctl. [devel-0-0-18]
++
++ * ioctl: removed fist_ioctl stuff, that is not needed for
++ now.
++
++2005-05-03 <mk@mary>
++
++ * file.c: simplified mini_fo_open and mini_fo_setattr using
++ new state changing functions. [devel-0-0-17]
++
++ * inode.c: Fixed getattr state bug (see below) in 2.4 function
++ mini_fo_inode revalidate.
++
++ * inode.c: found an other bug in mini_fo_getattr. States are not
++ reliable in this function, as a file can be opened, unlinked and
++ the getattr function called. This results in a deleted dentry
++ with an inode. Fix is to ignore states and simply use the inode
++ available.
++
++2005-04-29 <mk@mary>
++
++ * file.c: Bugfix and cleanup in fasync and fsync. [devel-0-0-16]
++
++ * file.c: do not use mini_fo_lock so the generic version is
++ used (I guess).
++
++ * inode.c: getattr, never call getattr on lower files, as this
++ will cause the inum to change.
++
++ * inode.c: rename_reg_file renamed to rename_nondir, as it
++ doesn't matter as long it't not a dir. Removed all
++ rename_dev_file etc.
++
++ * tagged as devel-0-0-15
++
++ * inode.c: added support for chosing support for extended
++ attrs at compile time by XATTR define in mini_fo.h .
++
++ * inode.c: fixed mini_fo_getattr to use mini_fo inode and not
++ lower again, what avoids inode number changes that confused
++ rm again. This is the proper solution.
++
++2005-04-24 <mk@mary>
++
++ * all files: updated Copyright notive to 2005. [devel-0-0-14]
++
++ * inode.c: fixed mini_fo_getattr to not change the inode
++ number, even if lower files change.
++
++ * super.c: fixed a bug that caused deleted base file to show
++ up suddenly after some time, or after creating a special
++ file. The problem was that after some time or after special
++ file creating sync_sb_inodes is called by the vfs, that
++ called our mini_fo_put_inode. There was (wrongly) called
++ __meta_put_lists, that nuked the lists, although the inode
++ was going to continue its life. Moving __meta_put_lists to
++ mini_fo_clear_inode, where an inode is really destroyed,
++ solved the problem.
++
++
++2005-04-23 <mk@mary>
++
++ * state.c, aux.c: more cleaning up and
++ simplifications. [devel-0-0-13]
++
++ * inode.c: implemented mini_fo_getattr, that was required for
++ 2.6 because inode_revalidate has been remove there, and the
++ old "du" bug returned.
++
++
++2005-04-20 <mk@mary>
++
++ * aux.c: get_neg_sto_dentry(): allow to be called for dentries
++ in state UNMODIFIED, NON_EXISTANT _and_ DELETED.
++
++2005-04-19 <mk@mary>
++
++ * Fixed a bug under 2.6 that caused files deleted via mini_fo
++ not to be deleted properly and therefore the fs filled up
++ untill no memory was left. [devel-0-0-12]
++
++ * Added basic hard link support. This means that creating
++ hardlinks will work, but existing ones will be treated as
++ individual files. [devel-0-0-11]
++
++2005-04-17 <mk@mary>
++
++ * Bugfixes
++
++2005-04-13 root <mk@mary>

++
++2005-04-12 <mk@mary>
++
++ * Porting to 2.6 started, which is easier than expected, also
++ due to Olivier previous work.
++
++2005-04-08 <mk@mary>
++
++ * Fixed the bug that caused du to return invalid sizes of
++ directory trees. The problem was that
++ mini_fo_inode_revalidate didn't always copy the attributes
++ from the base inode properly.
++
++2005-04-01 Markus Klotzbuecher <mk@chasey>

++
++2005-03-31 Markus Klotzbuecher <mk@chasey>

++
++2005-03-28 Markus Klotzbuecher <mk@chasey>

++
++2005-03-22 Markus Klotzbuecher <mk@chasey>
++
++ * Finished implementing lightweight directory renaming. Some

++ Next is to implement testcases for the testsuite and confirm
++ everything is really working ok.
++
++2005-03-18 Markus Klotzbuecher <mk@chasey>
++
++ * Finished implementing meta.c stuff required for directory

++
++2005-03-17 Markus Klotzbuecher <mk@chasey>
++
++ * Fixed all compile warnings + an extremly old bug that
++ somehow crept in while reworking the wol stuff to the META
++ system. Turning on -Werror again... :-)
++
++ * Fixed some bugs in the new rename_reg_file function.
++
++ * Rewrote mini_fo rename and split it into several
++ subfunctions, that handle the different types
++ seperately. Rewrote the regular file function aswell, as it
++ was implemented somewhat inefficient.
++
++2005-03-16 Markus Klotzbuecher <mk@chasey>
++
++ * Implemented new META subsystem, removed old WOL stuff in favor
++ if it.
++
++ * After some basic testing everything seems ok...
++
++2005-03-11 Markus Klotzbuecher <mk@chasey>
++
++ * Renaming a non regular file caused trouble because I always
++ tried to copy the contents. Now I only do this for regular
++ files. mini_fo_rename still isn't implemented properly, renaming
++ of device files, symlinks etc. results in a empty regular file
++ instead of the proper type.
++
++ * Directory renaming suddenly works! What a surprise! I guess
++ this is because renaming is implemented as making a copy and
++ removing the original. Still this might not work
++ everywhere...
++
++2005-03-09 Markus Klotzbuecher <mk@chasey>
++
++ * Bugfix, when a mini_fo directory that exists in storage
++ (state: MODIFIED, CREATED and DEL_REWRITTEN) is deleted, a
++ possibly existing WOL file contained in it needs to be
++ deleted too.
++
++ * Starting cleanup: defined state names in order to get rid of
++ the state numbers.
++
++2005-03-08 Markus Klotzbuecher <mk@chasey>
++
++ * Makefile fix, fist_ioctl was built against wrong sources if ARCH=um
++
++ * Fixed a bug in dentry.c, mini_fo_d_hash. In state 4 =
++ DEL_REWRITTEN the hash was calculated from the base dentry,
++ which was wrong and and caused assertions in
++ __mini_fo_hidden_dentry to fail.
++
++2005-02-21 <mk@mary>
++
++ * Implemented directory deleting (inode.c)
++
++ * main.c: made mini_fo_parse_options a little more robust.
++
++2004-12-22 <mk@mary>
++
++ * Makefile cleanup and uml stuff, removed unneccessary files
++
++ * Created a new and hopefully more informative README
++
++ * CHANGELOG: created a new CHANGELOG and added old entries reversely
++
++
++2004-10-24 Gleb Natapov <gleb@nbase.co.il>
++
++ * Fix: owner and group where not correctly copied from base to
++ storage.
++
++
++2004-10-05 Gleb Natapov <gleb@nbase.co.il>
++
++ * Implementation of fsync, fasync and lock mini_fo functions.
++
++
++2004-09-29 Bob Lee <bob@pantasys.com>
++
++ * Fix of a serious pointer bug
++
++
++2004-09-28 Gleb Natapov <gleb@nbase.co.il>
++
++ * Implementation of mini_fo_mknod and mini_fo_rename, support
++ for device files.

++README for the mini_fo overlay file system
++=========================================
++
++
++WHAT IS MINI_FO?
++----------------
++
++mini_fo is a virtual kernel file system that can make read-only
++file systems writable. This is done by redirecting modifying operations
++to a writeable location called "storage directory", and leaving the
++original data in the "base directory" untouched. When reading, the
++file system merges the modifed and original data so that only the
++newest versions will appear. This occurs transparently to the user,
++who can access the data like on any other read-write file system.
++
++Base and storage directories may be located on the same or on
++different partitions and may be of different file system types. While
++the storage directory obviously needs to be writable, the base may or
++may not be writable, what doesn't matter as it will no be modified
++anyway.
++
++
++WHAT IS GOOD FOR?
++-----------------
++
++The primary purpose of the mini_fo file system is to allow easy
++software updates to embedded systems, that often store their root
++file system in a read-only flash file system, but there are many
++more as for example sandboxing, or for allowing live-cds to
++permanently store information.
++
++
++BUILDING
++--------
++This should be simple. Adjust the Makefile to point to the correct
++kernel headers you want to build the module for. Then:
++
++ # make
++
++should build "mini_fo.o" for a 2.4 kernel or "mini_fo.ko" for a 2.6
++kernel.
++
++If you are building the module for you current kernel, you can install
++the module (as root):
++
++ # make install
++
++or uninstall with
++
++ # make uninstall
++
++
++USING THE FILE SYSTEM
++--------------------
++
++the general mount syntax is:
++
++ mount -t mini_fo -o base=<base directory>,sto=<storage directory>\
++ <base directory> <mount point>
++
++Example:
++
++You have mounted a cdrom to /mnt/cdrom and want to modifiy some files
++on it:
++
++load the module (as root)
++
++ # insmod mini_fo.o for a 2.4 kernel or
++
++ # insmod mini_fo.ko for a 2.6 kernel
++
++
++create a storage dir in tmp and a mountpoint for mini_fo:
++
++ # mkdir /tmp/sto
++ # mkdir /mnt/mini_fo
++
++and mount the mini_fo file system:
++
++ # mount -t mini_fo -o base=/mnt/cdrom,sto=/tmp/sto /mnt/cdrom /mnt/mini_fo
++
++
++Now the data stored on the cd can be accessed via the mini_fo
++mountpoint just like any read-write file system, files can be modified
++and deleted, new ones can be created and so on. When done unmount the
++file system:
++
++ # unmount /mnt/mini_fo
++
++Note that if the file system is mounted again using the same storage
++file system, of course it will appear in the modified state again. If
++you remount it using an new empty storage directory, it will be
++unmodified. Therefore by executing:
++
++ # cd /tmp/sto
++ # rm -rf *
++
++you can nuke all the changes you made to the original file system. But
++ remember NEVER do this while the mini_fo file system is mounted!
++
++
++Alternatively you can use the mini_fo-overlay bash script, that
++simplifies managing mini_fo mounts. See TOOLS Section.
++
++
++TOOLS
++-----
++
++mini_fo-merge (experimental):
++
++This is a bash script that will merge changes contained in the storage
++directory back to the base directory. This allows mini_fo to function
++as a cache file system by overlaying a slow (network, ...) file system
++and using a fast (ramdisk, ...) as storage. When done, changes can be
++merged back to the (slow) base with mini_fo-merge. See "mini_fo-merge
++-h" for details.
++
++It can be usefull for merging changes back after a successfull test
++(patches, software updates...)
++
++
++mini_fo-overlay:
++
++This bash script simplifies managing one or more mini_fo mounts. For
++overlaying a directory called "basedir1", you can just call:
++
++ # mini_fo-overlay basedir1
++
++This will mount mini_fo with "basedir1" as base, "/tmp/sto-basedir1/"
++as storage to "/mnt/mini_fo-basedir1/". It has more options though,
++type "mini_fo-overlay -h" for details.
++
++
++DOCUMENTATION, REPORTING BUGS, GETTING HELP
++-------------------------------------------
++
++Please visit the mini_fo project page at:
++
++http://www.denx.de/twiki/bin/view/Know/MiniFOHome
++
++
++WARNINGS
++--------
++
++Never modify the base or the storage directorys while the mini_fo
++file system is mounted, or you might crash you system. Simply accessing
++and reading should not cause any trouble.
++
++Exporting a mini_fo mount point via NFS has not been tested, and may
++or may not work.
++
++Check the RELEASE_NOTES for details on bugs and features.

++Release: mini_fo-0.6.1 (v0-6-1)
++Date: 21.09.2005
++
++
++Changes:
++--------
++v0-6-1:
++
++- bugfixes (see ChangeLog)
++
++- two helper scripts "mini_fo_merge" and "mini_fo_overlay" (see
++ README for details).
++
++v0-6-0:
++
++- Support for 2.4 and 2.6 (see Makefile)
++
++- Partial hard link support (creating works as expected, but already
++ existing links in the base file system will be treated as if they
++ were individual files).
++
++- Various bugfixes and cleanups.
++
++
++v0-6-0-pre1:
++
++- This is mini_fo-0-6-0-pre1! This release is a complete rewrite of
++ many vital mini_fo parts such as the old whiteout list code which
++ has been replaced by the new META subsystem.
++
++- Light weight directory renaming implemented. This means if a
++ directory is renamed via the mini_fo filesystem this will no longer
++ result in a complete copy in storage, instead only one empty
++ directory will be created. All base filed contained in the original
++ directory stay there until modified.
++
++- Special files (creating, renaming, deleting etc.) now working.
++
++- Many bugfixes and cleanup, mini_fo is now a lot more stable.
++
++
++v0-5-10:
++
++- Final release of the 0-5-* versions. Next will be a complete rewrite
++ of many features. This release contains several bugfixes related to
++ directory renaming.
++
++
++v0-5-10-pre6:
++
++- Lots of cleanup and several bugfixes related to directory deleting
++
++- Directory renaming suddenly works, what is most likely due to the
++ fact tha that "mv" is smart: if the classic rename doesn't work it
++ will assume that source and target file are on different fs and will
++ copy the directory and try to remove the source directory. Until
++ directory removing wasn't implemented, it would fail to do this and
++ rollback.
++ So, directory renaming works for now, but it doesn't yet do what you
++ would expect from a overlay fs, so use with care.
++
++
++v0-5-10-pre5:
++
++- implemented directory deleting
++- made parsing of mount options more stable
++- New format of mount options! (See README)
++- I can't reproduce the unknown panic with 2.4.25 anymore, so I'll
++ happily assume it never existed!
++
++
++Implemented features:
++---------------------
++
++- creating hard links (see BUGS on already existing hard links)
++- lightweight directory renaming
++- renaming device files, pipes, sockets, etc.
++- creating, renaming, deleting of special files
++- deleting directorys
++- general directory reading (simple "ls" )
++- creating files in existing directorys
++- creating directorys
++- renaming files.
++- reading and writing files (involves opening)
++- appending to files (creates copy in storage)
++- deleting files
++- llseek works too, what allows editors to work
++- persistency (a deleted file stay deleted over remounts)
++- use of symbolic links
++- creating of device files
++
++
++Not (yet) implemented features:
++-------------------------------
++
++- full hard link support.
++
++
++
++BUGS:
++-----
++
++Hard links in the base file system will be treated as individual
++files, not as links to one inode.
++
++The main problem with hard links isn't allowing to create them, but
++their pure existence. If you modify a base hard link, the changes made
++will only show up on this link, the other link will remain in the
++original state. I hope to fix this someday. Please note that this does
++not effect the special hard links '.' and '..', that are handled
++seperately by the lower fs.

+- Give the number of Blocks to reserve for checkpointing.
+- Checkpointing saves the state at unmount so that mounting is
+- much faster as a scan of all the flash to regenerate this state
+- is not needed. These Blocks are reserved per partition, so if
+- you have very small partitions the default (10) may be a mess
+- for you. You can set this value to 0, but that does not mean
+- checkpointing is disabled at all. There only won't be any
+- specially reserved blocks for checkpointing, so if there is
+- enough free space on the filesystem, it will be used for
+- checkpointing.
+-
+- If unsure, leave at default (10), but don't wonder if there are
+- always 2MB used on your large page device partition (10 x 2k
+- pagesize). When using small partitions or when being very small
+- on space, you probably want to set this to zero.

++GPIOMMC - Driver for an MMC/SD card on a bitbanging GPIO SPI bus
++================================================================
++
++The gpiommc module hooks up the mmc_spi and spi_gpio modules for running an
++MMC or SD card on GPIO pins.
++
++Two interfaces for registering a new MMC/SD card device are provided:
++A static platform-device based mechanism and a dynamic configfs based interface.
++
++
++Registering devices via platform-device
++=======================================
++
++The platform-device interface is used for registering MMC/SD devices that are
++part of the hardware platform. This is most useful only for embedded machines
++with MMC/SD devices statically connected to the platform GPIO bus.
++
++The data structures are declared in <linux/mmc/gpiommc.h>.
++
++To register a new device, define an instance of struct gpiommc_platform_data.
++This structure holds any information about how the device is hooked up to the
++GPIO pins and what hardware modes the device supports. See the docbook-style
++documentation in the header file for more information on the struct fields.
++
++Then allocate a new instance of a platform device by doing:
++
++ pdev = platform_device_alloc(GPIOMMC_PLATDEV_NAME, gpiommc_next_id());
++
++This will allocate the platform device data structures and hook it up to the
++gpiommc driver.
++Then add the gpiommc_platform_data to the platform device.
++
++ err = platform_device_add_data(pdev, pdata, sizeof(struct gpiommc_platform_data));
++
++You may free the local instance of struct gpiommc_platform_data now. (So the
++struct may be allocated on the stack, too).
++Now simply register the platform device.
++
++ err = platform_device_add(pdev);
++
++Done. The gpiommc probe routine will be invoked now and you should see a kernel
++log message for the added device.
++
++
++Registering devices via configfs
++================================
++
++MMC/SD cards connected via GPIO often are a pretty dynamic thing, as for example
++selfmade hacks for soldering an MMC/SD card to standard GPIO pins on embedded
++hardware are a common situation.
++So we provide a dynamic interface to conveniently handle adding and removing
++devices from userspace, without the need to recompile the kernel.
++
++The "gpiommc" subdirectory at the configfs mountpoint is used for handling
++the dynamic configuration.
++
++To create a new device, it must first be allocated with mkdir.
++The following command will allocate a device named "my_mmc":
++ mkdir /config/gpiommc/my_mmc
++
++There are several configuration files available in the new
++/config/gpiommc/my_mmc/ directory:
++
++gpio_data_in = The SPI data-IN GPIO pin number.
++gpio_data_out = The SPI data-OUT GPIO pin number.
++gpio_clock = The SPI Clock GPIO pin number.
++gpio_chipselect = The SPI Chipselect GPIO pin number.
++gpio_chipselect_activelow = Boolean. If 0, Chipselect is active-HIGH.
++ If 1, Chipselect is active-LOW.
++spi_mode = The SPI data mode. Can be 0-3.
++spi_delay = Enable all delays in the lowlevel bitbanging.
++max_bus_speed = The maximum SPI bus speed. In Hertz.
++
++register = Not a configuration parameter.
++ Used to register the configured card
++ with the kernel.
++
++The device must first get configured and then registered by writing "1" to
++the "register" file.
++The configuration parameters "gpio_data_in", "gpio_data_out", "gpio_clock"
++and "gpio_chipselect" are essential and _must_ be configured before writing
++"1" to the "register" file. The registration will fail, otherwise.
++
++The default values for the other parameters are:
++gpio_chipselect_activelow = 1 (CS active-LOW)
++spi_mode = 0 (SPI_MODE_0)
++spi_delay = 1 (enabled)
++max_bus_speed = 5000000 (5 Mhz)
++
++Configuration values can not be changed after registration. To unregister
++the device, write a "0" to the "register" file. The configuration can be
++changed again after unregistering.
++
++To completely remove the device, simply rmdir the directory
++(/config/gpiommc/my_mmc in this example).
++There's no need to first unregister the device before removing it. That will
++be done automatically.

+X-Git-Tag: next-20090817~86^2~1^6
+X-Git-Url: http://git.kernel.org/?p=linux%2Fkernel%2Fgit%2Fnext%2Flinux-next.git;a=commitdiff_plain;h=369842658a36bcea28ecb643ba4bdb53919330dd
+
+ARM: 5677/1: ARM support for TIF_RESTORE_SIGMASK/pselect6/ppoll/epoll_pwait
+
+This patch adds support for TIF_RESTORE_SIGMASK to ARM's
+signal handling, which allows to hook up the pselect6, ppoll,
+and epoll_pwait syscalls on ARM.
+
+Tested here with eabi userspace and a test program with a
+deliberate race between a child's exit and the parent's
+sigprocmask/select sequence. Using sys_pselect6() instead
+of sigprocmask/select reliably prevents the race.
+
+The other arch's support for TIF_RESTORE_SIGMASK has evolved
+over time:
+
+In 2.6.16:
+- add TIF_RESTORE_SIGMASK which parallels TIF_SIGPENDING
+- test both when checking for pending signal [changed later]
+- reimplement sys_sigsuspend() to use current->saved_sigmask,
+ TIF_RESTORE_SIGMASK [changed later], and -ERESTARTNOHAND;
+ ditto for sys_rt_sigsuspend(), but drop private code and
+ use common code via __ARCH_WANT_SYS_RT_SIGSUSPEND;
+- there are now no "extra" calls to do_signal() so its oldset
+ parameter is always &current->blocked so need not be passed,
+ also its return value is changed to void
+- change handle_signal() to return 0/-errno
+- change do_signal() to honor TIF_RESTORE_SIGMASK:
+ + get oldset from current->saved_sigmask if TIF_RESTORE_SIGMASK
+ is set
+ + if handle_signal() was successful then clear TIF_RESTORE_SIGMASK
+ + if no signal was delivered and TIF_RESTORE_SIGMASK is set then
+ clear it and restore the sigmask
+- hook up sys_pselect6() and sys_ppoll()
+
+In 2.6.19:
+- hook up sys_epoll_pwait()
+
+In 2.6.26:
+- allow archs to override how TIF_RESTORE_SIGMASK is implemented;
+ default set_restore_sigmask() sets both TIF_RESTORE_SIGMASK and
+ TIF_SIGPENDING; archs need now just test TIF_SIGPENDING again
+ when checking for pending signal work; some archs now implement
+ TIF_RESTORE_SIGMASK as a secondary/non-atomic thread flag bit
+- call set_restore_sigmask() in sys_sigsuspend() instead of setting
+ TIF_RESTORE_SIGMASK
+
+In 2.6.29-rc:
+- kill sys_pselect7() which no arch wanted
+
+So for 2.6.31-rc6/ARM this patch does the following:
+- Add TIF_RESTORE_SIGMASK. Use the generic set_restore_sigmask()
+ which sets both TIF_SIGPENDING and TIF_RESTORE_SIGMASK, so
+ TIF_RESTORE_SIGMASK need not claim one of the scarce low thread
+ flags, and existing TIF_SIGPENDING and _TIF_WORK_MASK tests need
+ not be extended for TIF_RESTORE_SIGMASK.
+- sys_sigsuspend() is reimplemented to use current->saved_sigmask
+ and set_restore_sigmask(), making it identical to most other archs
+- The private code for sys_rt_sigsuspend() is removed, instead
+ generic code supplies it via __ARCH_WANT_SYS_RT_SIGSUSPEND.
+- sys_sigsuspend() and sys_rt_sigsuspend() no longer need a pt_regs
+ parameter, so their assembly code wrappers are removed.
+- handle_signal() is changed to return 0 on success or -errno.
+- The oldset parameter to do_signal() is now redundant and removed,
+ and the return value is now also redundant and changed to void.
+- do_signal() is changed to honor TIF_RESTORE_SIGMASK:
+ + get oldset from current->saved_sigmask if TIF_RESTORE_SIGMASK
+ is set
+ + if handle_signal() was successful then clear TIF_RESTORE_SIGMASK
+ + if no signal was delivered and TIF_RESTORE_SIGMASK is set then
+ clear it and restore the sigmask
+- Hook up sys_pselect6, sys_ppoll, and sys_epoll_pwait.

+Subject: Fix the VFP handling on the Feroceon CPU
+X-Git-Url: http://www.linux-arm.org/git?p=linux-2.6.git;a=commitdiff_plain;h=85d6943af50537d3aec58b967ffbd3fec88453e9;hp=26584853a44c58f3d6ac7360d697a2ddcd1a3efa
+
+Fix the VFP handling on the Feroceon CPU
+
+This CPU generates synchronous VFP exceptions in a non-standard way -
+the FPEXC.EX bit set but without the FPSCR.IXE bit being set like in the
+VFP subarchitecture 1 or just the FPEXC.DEX bit like in VFP
+subarchitecture 2. The main problem is that the faulty instruction
+(which needs to be emulated in software) will be restarted several times
+(normally until a context switch disables the VFP). This patch ensures
+that the VFP exception is treated as synchronous.

+Subject: [PATCH] Squashfs: Make unlzma available to non initramfs/initrd code
+
+Add a config option DECOMPRESS_LZMA_NEEDED which allows subsystems to
+specify they need the unlzma code. Normally decompress_unlzma.c is
+compiled with __init and unlzma is not exported to modules.

+GCC 4.4.x looks to be adding support for generating out-of-line register
+saves/restores based on:
+
+http://gcc.gnu.org/ml/gcc-patches/2008-04/msg01678.html
+
+This breaks the kernel build as we'd have to link with libgcc to get the
+implementation of the register save/restores.
+
+To workaround this issue, we just stole the save/restore code from gcc
+and simplified it down for our needs (integer only). We only do this if
+PPC32 as gcc makes believe the linker on ppc64 will deal with this and
+only if CONFIG_CC_OPTIMIZE_FOR_SIZE is set (thus -Os).
+
+Signed-off-by: Kumar Gala <[EMAIL PROTECTED]>
+---
+
+If someone using cutting edge toolchains for ppc64 could test and make
+sure if we enable CONFIG_CC_OPTIMIZE_FOR_SIZE things work that would be
+nice.

+From: Albin Tonnerre <albin.tonnerre@free-electrons.com>
+Date: Wed, 23 Sep 2009 15:57:38 -0700
+Subject: [PATCH] include/linux/unaligned/{l,b}e_byteshift.h: fix usage for compressed kernels
+
+When unaligned accesses are required for uncompressing a kernel (such as
+for LZO decompression on ARM in a patch that follows), including
+<linux/kernel.h> causes issues as it brings in a lot of things that are
+not available in the decompression environment.
+
+linux/kernel.h brings at least:
+extern int console_printk[];
+extern const char hex_asc[];
+which causes errors at link-time as they are not available when
+compiling the pre-boot environement. There are also a few others:
+
+ arch/arm/boot/compressed/misc.o: In function `valid_user_regs':
+ arch/arm/include/asm/ptrace.h:158: undefined reference to `elf_hwcap'
+ arch/arm/boot/compressed/misc.o: In function `console_silent':
+ include/linux/kernel.h:292: undefined reference to `console_printk'
+ arch/arm/boot/compressed/misc.o: In function `console_verbose':
+ include/linux/kernel.h:297: undefined reference to `console_printk'
+ arch/arm/boot/compressed/misc.o: In function `pack_hex_byte':
+ include/linux/kernel.h:360: undefined reference to `hex_asc'
+ arch/arm/boot/compressed/misc.o: In function `hweight_long':
+ include/linux/bitops.h:45: undefined reference to `hweight32'
+ arch/arm/boot/compressed/misc.o: In function `__cmpxchg_local_generic':
+ include/asm-generic/cmpxchg-local.h:21: undefined reference to `wrong_size_cmpxchg'
+ include/asm-generic/cmpxchg-local.h:42: undefined reference to `wrong_size_cmpxchg'
+ arch/arm/boot/compressed/misc.o: In function `__xchg':
+ arch/arm/include/asm/system.h:309: undefined reference to `__bad_xchg'

++ * "railroad normal form" in parsing technology). Each node is an opcode
++ * plus a "next" pointer, possibly plus an operand. "Next" pointers of
++ * all nodes except BRANCH implement concatenation; a "next" pointer with
++ * a BRANCH on both ends of it is connecting two alternatives. (Here we
++ * have one of the subtle syntax dependencies: an individual BRANCH (as
++ * opposed to a collection of them) is never concatenated with anything
++ * because of operator precedence.) The operand of some types of node is
++ * a literal string; for others, it is a node leading into a sub-FSM. In
++ * particular, the operand of a BRANCH node is the first node of the branch.
++ * (NB this is *not* a tree structure: the tail of the branch connects
++ * to the thing following the set of BRANCHes.) The opcodes are:

++ *
++ * Authors: Patrick McHardy, <kaber@trash.net>
++ *
++ * The first version was written by Martin Devera, <devik@cdi.cz>
++ *
++ * Credits: Jan Rafaj <imq2t@cedric.vabo.cz>
++ * - Update patch to 2.4.21
++ * Sebastian Strollo <sstrollo@nortelnetworks.com>
++ * - Fix "Dead-loop on netdevice imq"-issue
++ * Marcel Sebek <sebek64@post.cz>
++ * - Update to 2.6.2-rc1
++ *
++ * After some time of inactivity there is a group taking care
++ * of IMQ again: http://www.linuximq.net
++ *
++ *
++ * 2004/06/30 - New version of IMQ patch to kernels <=2.6.7
++ * including the following changes:
++ *
++ * - Correction of ipv6 support "+"s issue (Hasso Tepper)
++ * - Correction of imq_init_devs() issue that resulted in
++ * kernel OOPS unloading IMQ as module (Norbert Buchmuller)
++ * - Addition of functionality to choose number of IMQ devices
++ * during kernel config (Andre Correa)
++ * - Addition of functionality to choose how IMQ hooks on
++ * PRE and POSTROUTING (after or before NAT) (Andre Correa)
++ * - Cosmetic corrections (Norbert Buchmuller) (Andre Correa)
++ *
++ *
++ * 2005/12/16 - IMQ versions between 2.6.7 and 2.6.13 were
++ * released with almost no problems. 2.6.14-x was released
++ * with some important changes: nfcache was removed; After
++ * some weeks of trouble we figured out that some IMQ fields
++ * in skb were missing in skbuff.c - skb_clone and copy_skb_header.
++ * These functions are correctly patched by this new patch version.
++ *
++ * Thanks for all who helped to figure out all the problems with
++ * 2.6.14.x: Patrick McHardy, Rune Kock, VeNoMouS, Max CtRiX,
++ * Kevin Shanahan, Richard Lucassen, Valery Dachev (hopefully
++ * I didn't forget anybody). I apologize again for my lack of time.
++ *
++ *
++ * 2008/06/17 - 2.6.25 - Changed imq.c to use qdisc_run() instead
++ * of qdisc_restart() and moved qdisc_run() to tasklet to avoid
++ * recursive locking. New initialization routines to fix 'rmmod' not
++ * working anymore. Used code from ifb.c. (Jussi Kivilinna)
++ *
++ * 2008/08/06 - 2.6.26 - (JK)
++ * - Replaced tasklet with 'netif_schedule()'.
++ * - Cleaned up and added comments for imq_nf_queue().
++ *
++ * 2009/04/12
++ * - Add skb_save_cb/skb_restore_cb helper functions for backuping
++ * control buffer. This is needed because qdisc-layer on kernels
++ * 2.6.27 and newer overwrite control buffer. (Jussi Kivilinna)
++ * - Add better locking for IMQ device. Hopefully this will solve
++ * SMP issues. (Jussi Kivilinna)
++ * - Port to 2.6.27
++ * - Port to 2.6.28
++ * - Port to 2.6.29 + fix rmmod not working
++ *
++ * 2009/04/20 - (Jussi Kivilinna)
++ * - Use netdevice feature flags to avoid extra packet handling
++ * by core networking layer and possibly increase performance.
++ *
++ * Also, many thanks to pablo Sebastian Greco for making the initial
++ * patch and to those who helped the testing.
++ *
++ * More info at: http://www.linuximq.net/ (Andre Correa)

++ * inode.c: found an other bug in mini_fo_getattr. States are not
++ reliable in this function, as a file can be opened, unlinked and
++ the getattr function called. This results in a deleted dentry
++ with an inode. Fix is to ignore states and simply use the inode
++ available.
++
++2005-04-29 <mk@mary>
++
++ * file.c: Bugfix and cleanup in fasync and fsync. [devel-0-0-16]
++
++ * file.c: do not use mini_fo_lock so the generic version is
++ used (I guess).
++
++ * inode.c: getattr, never call getattr on lower files, as this
++ will cause the inum to change.
++
++ * inode.c: rename_reg_file renamed to rename_nondir, as it
++ doesn't matter as long it't not a dir. Removed all
++ rename_dev_file etc.
++
++ * tagged as devel-0-0-15
++
++ * inode.c: added support for chosing support for extended
++ attrs at compile time by XATTR define in mini_fo.h .
++
++ * inode.c: fixed mini_fo_getattr to use mini_fo inode and not
++ lower again, what avoids inode number changes that confused
++ rm again. This is the proper solution.
++
++2005-04-24 <mk@mary>
++
++ * all files: updated Copyright notive to 2005. [devel-0-0-14]
++
++ * inode.c: fixed mini_fo_getattr to not change the inode
++ number, even if lower files change.
++
++ * super.c: fixed a bug that caused deleted base file to show
++ up suddenly after some time, or after creating a special
++ file. The problem was that after some time or after special
++ file creating sync_sb_inodes is called by the vfs, that
++ called our mini_fo_put_inode. There was (wrongly) called
++ __meta_put_lists, that nuked the lists, although the inode
++ was going to continue its life. Moving __meta_put_lists to
++ mini_fo_clear_inode, where an inode is really destroyed,
++ solved the problem.
++
++
++2005-04-23 <mk@mary>
++
++ * state.c, aux.c: more cleaning up and
++ simplifications. [devel-0-0-13]
++
++ * inode.c: implemented mini_fo_getattr, that was required for
++ 2.6 because inode_revalidate has been remove there, and the
++ old "du" bug returned.
++
++
++2005-04-20 <mk@mary>
++
++ * aux.c: get_neg_sto_dentry(): allow to be called for dentries
++ in state UNMODIFIED, NON_EXISTANT _and_ DELETED.
++
++2005-04-19 <mk@mary>
++
++ * Fixed a bug under 2.6 that caused files deleted via mini_fo
++ not to be deleted properly and therefore the fs filled up
++ untill no memory was left. [devel-0-0-12]
++
++ * Added basic hard link support. This means that creating
++ hardlinks will work, but existing ones will be treated as
++ individual files. [devel-0-0-11]
++
++2005-04-17 <mk@mary>
++
++ * Bugfixes
++
++2005-04-13 root <mk@mary>
++
++ * Added file state.c for the state transition
++ functions. Doesn't work very well yet, though...
++
++2005-04-12 <mk@mary>
++
++ * Porting to 2.6 started, which is easier than expected, also
++ due to Olivier previous work.
++
++2005-04-08 <mk@mary>
++
++ * Fixed the bug that caused du to return invalid sizes of
++ directory trees. The problem was that
++ mini_fo_inode_revalidate didn't always copy the attributes
++ from the base inode properly.
++
++2005-04-01 Markus Klotzbuecher <mk@chasey>
++
++ * Merged devel branch back to main trunk and updated the
++ RELEASE notes. This will be 0-6-0-pre1.
++
++2005-03-31 Markus Klotzbuecher <mk@chasey>
++
++ * Fixed some bugs in rename_reg_file, that only showed up in
++ the kernel compile test. Kernel compiles cleanly ontop of
++ mini_fo, now also make mrproper etc. work. Seems pretty stable.
++
++2005-03-28 Markus Klotzbuecher <mk@chasey>
++
++ * Many, many directory renaming bugfixes and a lot of other
++ cleanup. Dir renaming seems to work relatively stable.
++
++2005-03-22 Markus Klotzbuecher <mk@chasey>
++
++ * Finished implementing lightweight directory renaming. Some
++ basic testing indicates it works fine.
++ Next is to implement testcases for the testsuite and confirm
++ everything is really working ok.
++
++2005-03-18 Markus Klotzbuecher <mk@chasey>
++
++ * Finished implementing meta.c stuff required for directory
++ renaming.
++
++2005-03-17 Markus Klotzbuecher <mk@chasey>
++
++ * Fixed all compile warnings + an extremly old bug that
++ somehow crept in while reworking the wol stuff to the META
++ system. Turning on -Werror again... :-)
++
++ * Fixed some bugs in the new rename_reg_file function.
++
++ * Rewrote mini_fo rename and split it into several
++ subfunctions, that handle the different types
++ seperately. Rewrote the regular file function aswell, as it
++ was implemented somewhat inefficient.
++
++2005-03-16 Markus Klotzbuecher <mk@chasey>
++
++ * Implemented new META subsystem, removed old WOL stuff in favor
++ if it.
++
++ * After some basic testing everything seems ok...
++
++2005-03-11 Markus Klotzbuecher <mk@chasey>
++
++ * Renaming a non regular file caused trouble because I always
++ tried to copy the contents. Now I only do this for regular
++ files. mini_fo_rename still isn't implemented properly, renaming
++ of device files, symlinks etc. results in a empty regular file
++ instead of the proper type.
++
++ * Directory renaming suddenly works! What a surprise! I guess
++ this is because renaming is implemented as making a copy and
++ removing the original. Still this might not work
++ everywhere...
++
++2005-03-09 Markus Klotzbuecher <mk@chasey>
++
++ * Bugfix, when a mini_fo directory that exists in storage
++ (state: MODIFIED, CREATED and DEL_REWRITTEN) is deleted, a
++ possibly existing WOL file contained in it needs to be
++ deleted too.
++
++ * Starting cleanup: defined state names in order to get rid of
++ the state numbers.
++
++2005-03-08 Markus Klotzbuecher <mk@chasey>
++
++ * Makefile fix, fist_ioctl was built against wrong sources if ARCH=um
++
++ * Fixed a bug in dentry.c, mini_fo_d_hash. In state 4 =
++ DEL_REWRITTEN the hash was calculated from the base dentry,
++ which was wrong and and caused assertions in
++ __mini_fo_hidden_dentry to fail.
++
++2005-02-21 <mk@mary>
++
++ * Implemented directory deleting (inode.c)
++
++ * main.c: made mini_fo_parse_options a little more robust.
++
++2004-12-22 <mk@mary>
++
++ * Makefile cleanup and uml stuff, removed unneccessary files
++
++ * Created a new and hopefully more informative README
++
++ * CHANGELOG: created a new CHANGELOG and added old entries reversely
++
++
++2004-10-24 Gleb Natapov <gleb@nbase.co.il>
++
++ * Fix: owner and group where not correctly copied from base to
++ storage.
++
++
++2004-10-05 Gleb Natapov <gleb@nbase.co.il>
++
++ * Implementation of fsync, fasync and lock mini_fo functions.
++
++
++2004-09-29 Bob Lee <bob@pantasys.com>
++
++ * Fix of a serious pointer bug
++
++
++2004-09-28 Gleb Natapov <gleb@nbase.co.il>
++
++ * Implementation of mini_fo_mknod and mini_fo_rename, support
++ for device files.

++README for the mini_fo overlay file system
++=========================================
++
++
++WHAT IS MINI_FO?
++----------------
++
++mini_fo is a virtual kernel file system that can make read-only
++file systems writable. This is done by redirecting modifying operations
++to a writeable location called "storage directory", and leaving the
++original data in the "base directory" untouched. When reading, the
++file system merges the modifed and original data so that only the
++newest versions will appear. This occurs transparently to the user,
++who can access the data like on any other read-write file system.
++
++Base and storage directories may be located on the same or on
++different partitions and may be of different file system types. While
++the storage directory obviously needs to be writable, the base may or
++may not be writable, what doesn't matter as it will no be modified
++anyway.
++
++
++WHAT IS GOOD FOR?
++-----------------
++
++The primary purpose of the mini_fo file system is to allow easy
++software updates to embedded systems, that often store their root
++file system in a read-only flash file system, but there are many
++more as for example sandboxing, or for allowing live-cds to
++permanently store information.
++
++
++BUILDING
++--------
++This should be simple. Adjust the Makefile to point to the correct
++kernel headers you want to build the module for. Then:
++
++ # make
++
++should build "mini_fo.o" for a 2.4 kernel or "mini_fo.ko" for a 2.6
++kernel.
++
++If you are building the module for you current kernel, you can install
++the module (as root):
++
++ # make install
++
++or uninstall with
++
++ # make uninstall
++
++
++USING THE FILE SYSTEM
++--------------------
++
++the general mount syntax is:
++
++ mount -t mini_fo -o base=<base directory>,sto=<storage directory>\
++ <base directory> <mount point>
++
++Example:
++
++You have mounted a cdrom to /mnt/cdrom and want to modifiy some files
++on it:
++
++load the module (as root)
++
++ # insmod mini_fo.o for a 2.4 kernel or
++
++ # insmod mini_fo.ko for a 2.6 kernel
++
++
++create a storage dir in tmp and a mountpoint for mini_fo:
++
++ # mkdir /tmp/sto
++ # mkdir /mnt/mini_fo
++
++and mount the mini_fo file system:
++
++ # mount -t mini_fo -o base=/mnt/cdrom,sto=/tmp/sto /mnt/cdrom /mnt/mini_fo
++
++
++Now the data stored on the cd can be accessed via the mini_fo
++mountpoint just like any read-write file system, files can be modified
++and deleted, new ones can be created and so on. When done unmount the
++file system:
++
++ # unmount /mnt/mini_fo
++
++Note that if the file system is mounted again using the same storage
++file system, of course it will appear in the modified state again. If
++you remount it using an new empty storage directory, it will be
++unmodified. Therefore by executing:
++
++ # cd /tmp/sto
++ # rm -rf *
++
++you can nuke all the changes you made to the original file system. But
++ remember NEVER do this while the mini_fo file system is mounted!
++
++
++Alternatively you can use the mini_fo-overlay bash script, that
++simplifies managing mini_fo mounts. See TOOLS Section.
++
++
++TOOLS
++-----
++
++mini_fo-merge (experimental):
++
++This is a bash script that will merge changes contained in the storage
++directory back to the base directory. This allows mini_fo to function
++as a cache file system by overlaying a slow (network, ...) file system
++and using a fast (ramdisk, ...) as storage. When done, changes can be
++merged back to the (slow) base with mini_fo-merge. See "mini_fo-merge
++-h" for details.
++
++It can be usefull for merging changes back after a successfull test
++(patches, software updates...)
++
++
++mini_fo-overlay:
++
++This bash script simplifies managing one or more mini_fo mounts. For
++overlaying a directory called "basedir1", you can just call:
++
++ # mini_fo-overlay basedir1
++
++This will mount mini_fo with "basedir1" as base, "/tmp/sto-basedir1/"
++as storage to "/mnt/mini_fo-basedir1/". It has more options though,
++type "mini_fo-overlay -h" for details.
++
++
++DOCUMENTATION, REPORTING BUGS, GETTING HELP
++-------------------------------------------
++
++Please visit the mini_fo project page at:
++
++http://www.denx.de/twiki/bin/view/Know/MiniFOHome
++
++
++WARNINGS
++--------
++
++Never modify the base or the storage directorys while the mini_fo
++file system is mounted, or you might crash you system. Simply accessing
++and reading should not cause any trouble.
++
++Exporting a mini_fo mount point via NFS has not been tested, and may
++or may not work.
++
++Check the RELEASE_NOTES for details on bugs and features.

++Release: mini_fo-0.6.1 (v0-6-1)
++Date: 21.09.2005
++
++
++Changes:
++--------
++v0-6-1:
++
++- bugfixes (see ChangeLog)
++
++- two helper scripts "mini_fo_merge" and "mini_fo_overlay" (see
++ README for details).
++
++v0-6-0:
++
++- Support for 2.4 and 2.6 (see Makefile)
++
++- Partial hard link support (creating works as expected, but already
++ existing links in the base file system will be treated as if they
++ were individual files).
++
++- Various bugfixes and cleanups.
++
++
++v0-6-0-pre1:
++
++- This is mini_fo-0-6-0-pre1! This release is a complete rewrite of
++ many vital mini_fo parts such as the old whiteout list code which
++ has been replaced by the new META subsystem.
++
++- Light weight directory renaming implemented. This means if a
++ directory is renamed via the mini_fo filesystem this will no longer
++ result in a complete copy in storage, instead only one empty
++ directory will be created. All base filed contained in the original
++ directory stay there until modified.
++
++- Special files (creating, renaming, deleting etc.) now working.
++
++- Many bugfixes and cleanup, mini_fo is now a lot more stable.
++
++
++v0-5-10:
++
++- Final release of the 0-5-* versions. Next will be a complete rewrite
++ of many features. This release contains several bugfixes related to
++ directory renaming.
++
++
++v0-5-10-pre6:
++
++- Lots of cleanup and several bugfixes related to directory deleting
++
++- Directory renaming suddenly works, what is most likely due to the
++ fact tha that "mv" is smart: if the classic rename doesn't work it
++ will assume that source and target file are on different fs and will
++ copy the directory and try to remove the source directory. Until
++ directory removing wasn't implemented, it would fail to do this and
++ rollback.
++ So, directory renaming works for now, but it doesn't yet do what you
++ would expect from a overlay fs, so use with care.
++
++
++v0-5-10-pre5:
++
++- implemented directory deleting
++- made parsing of mount options more stable
++- New format of mount options! (See README)
++- I can't reproduce the unknown panic with 2.4.25 anymore, so I'll
++ happily assume it never existed!
++
++
++Implemented features:
++---------------------
++
++- creating hard links (see BUGS on already existing hard links)
++- lightweight directory renaming
++- renaming device files, pipes, sockets, etc.
++- creating, renaming, deleting of special files
++- deleting directorys
++- general directory reading (simple "ls" )
++- creating files in existing directorys
++- creating directorys
++- renaming files.
++- reading and writing files (involves opening)
++- appending to files (creates copy in storage)
++- deleting files
++- llseek works too, what allows editors to work
++- persistency (a deleted file stay deleted over remounts)
++- use of symbolic links
++- creating of device files
++
++
++Not (yet) implemented features:
++-------------------------------
++
++- full hard link support.
++
++
++
++BUGS:
++-----
++
++Hard links in the base file system will be treated as individual
++files, not as links to one inode.
++
++The main problem with hard links isn't allowing to create them, but
++their pure existence. If you modify a base hard link, the changes made
++will only show up on this link, the other link will remain in the
++original state. I hope to fix this someday. Please note that this does
++not effect the special hard links '.' and '..', that are handled
++seperately by the lower fs.

+- Give the number of Blocks to reserve for checkpointing.
+- Checkpointing saves the state at unmount so that mounting is
+- much faster as a scan of all the flash to regenerate this state
+- is not needed. These Blocks are reserved per partition, so if
+- you have very small partitions the default (10) may be a mess

+- checkpointing is disabled at all. There only won't be any
+- specially reserved blocks for checkpointing, so if there is
+- enough free space on the filesystem, it will be used for
+- checkpointing.
+-
+- If unsure, leave at default (10), but don't wonder if there are
+- always 2MB used on your large page device partition (10 x 2k
+- pagesize). When using small partitions or when being very small
+- on space, you probably want to set this to zero.

+commit 5ced436d549d911ce610ea47d85f71fae5bbfce4
+Author: Lars-Peter Clausen <lars@metafoo.de>
+Date: Fri Jul 31 18:26:48 2009 +0200
+
+ ASoC: jack: Fix race in snd_soc_jack_add_gpios
+
+ The irq can fire as soon as it has been requested, thus all fields accessed
+ from within the irq handler must be initialized prior to requesting the irq.

+ Signed-off-by: Lars-Peter Clausen <lars@metafoo.de>

++GPIOMMC - Driver for an MMC/SD card on a bitbanging GPIO SPI bus
++================================================================
++
++The gpiommc module hooks up the mmc_spi and spi_gpio modules for running an
++MMC or SD card on GPIO pins.
++
++Two interfaces for registering a new MMC/SD card device are provided:
++A static platform-device based mechanism and a dynamic configfs based interface.
++
++
++Registering devices via platform-device
++=======================================
++
++The platform-device interface is used for registering MMC/SD devices that are
++part of the hardware platform. This is most useful only for embedded machines
++with MMC/SD devices statically connected to the platform GPIO bus.
++
++The data structures are declared in <linux/mmc/gpiommc.h>.
++
++To register a new device, define an instance of struct gpiommc_platform_data.
++This structure holds any information about how the device is hooked up to the
++GPIO pins and what hardware modes the device supports. See the docbook-style
++documentation in the header file for more information on the struct fields.
++
++Then allocate a new instance of a platform device by doing:
++
++ pdev = platform_device_alloc(GPIOMMC_PLATDEV_NAME, gpiommc_next_id());
++
++This will allocate the platform device data structures and hook it up to the
++gpiommc driver.
++Then add the gpiommc_platform_data to the platform device.
++
++ err = platform_device_add_data(pdev, pdata, sizeof(struct gpiommc_platform_data));
++
++You may free the local instance of struct gpiommc_platform_data now. (So the
++struct may be allocated on the stack, too).
++Now simply register the platform device.
++
++ err = platform_device_add(pdev);
++
++Done. The gpiommc probe routine will be invoked now and you should see a kernel
++log message for the added device.
++
++
++Registering devices via configfs
++================================
++
++MMC/SD cards connected via GPIO often are a pretty dynamic thing, as for example
++selfmade hacks for soldering an MMC/SD card to standard GPIO pins on embedded
++hardware are a common situation.
++So we provide a dynamic interface to conveniently handle adding and removing
++devices from userspace, without the need to recompile the kernel.
++
++The "gpiommc" subdirectory at the configfs mountpoint is used for handling
++the dynamic configuration.
++
++To create a new device, it must first be allocated with mkdir.
++The following command will allocate a device named "my_mmc":
++ mkdir /config/gpiommc/my_mmc
++
++There are several configuration files available in the new
++/config/gpiommc/my_mmc/ directory:
++
++gpio_data_in = The SPI data-IN GPIO pin number.
++gpio_data_out = The SPI data-OUT GPIO pin number.
++gpio_clock = The SPI Clock GPIO pin number.
++gpio_chipselect = The SPI Chipselect GPIO pin number.
++gpio_chipselect_activelow = Boolean. If 0, Chipselect is active-HIGH.
++ If 1, Chipselect is active-LOW.
++spi_mode = The SPI data mode. Can be 0-3.
++spi_delay = Enable all delays in the lowlevel bitbanging.
++max_bus_speed = The maximum SPI bus speed. In Hertz.
++
++register = Not a configuration parameter.
++ Used to register the configured card
++ with the kernel.
++
++The device must first get configured and then registered by writing "1" to
++the "register" file.
++The configuration parameters "gpio_data_in", "gpio_data_out", "gpio_clock"
++and "gpio_chipselect" are essential and _must_ be configured before writing
++"1" to the "register" file. The registration will fail, otherwise.
++
++The default values for the other parameters are:
++gpio_chipselect_activelow = 1 (CS active-LOW)
++spi_mode = 0 (SPI_MODE_0)
++spi_delay = 1 (enabled)
++max_bus_speed = 5000000 (5 Mhz)
++
++Configuration values can not be changed after registration. To unregister
++the device, write a "0" to the "register" file. The configuration can be
++changed again after unregistering.
++
++To completely remove the device, simply rmdir the directory
++(/config/gpiommc/my_mmc in this example).
++There's no need to first unregister the device before removing it. That will
++be done automatically.

+Subject: [PATCH] Squashfs: Make unlzma available to non initramfs/initrd code
+
+Add a config option DECOMPRESS_LZMA_NEEDED which allows subsystems to
+specify they need the unlzma code. Normally decompress_unlzma.c is
+compiled with __init and unlzma is not exported to modules.
+

+GCC 4.4.x looks to be adding support for generating out-of-line register
+saves/restores based on:
+
+http://gcc.gnu.org/ml/gcc-patches/2008-04/msg01678.html
+
+This breaks the kernel build as we'd have to link with libgcc to get the
+implementation of the register save/restores.
+
+To workaround this issue, we just stole the save/restore code from gcc
+and simplified it down for our needs (integer only). We only do this if
+PPC32 as gcc makes believe the linker on ppc64 will deal with this and
+only if CONFIG_CC_OPTIMIZE_FOR_SIZE is set (thus -Os).
+
+Signed-off-by: Kumar Gala <[EMAIL PROTECTED]>
+---
+
+If someone using cutting edge toolchains for ppc64 could test and make
+sure if we enable CONFIG_CC_OPTIMIZE_FOR_SIZE things work that would be
+nice.

+From b53e9b5ebd5c6e718f54bcacd4e97b71533ca681 Mon Sep 17 00:00:00 2001
+From: Tony Lindgren <tony@atomide.com>
+Date: Thu, 14 Jan 2010 20:36:55 +0100
+Subject: [PATCH] ARM: 5882/1: ARM: Fix uncompress code compile for different defines of flush(void)
+
+Because of the include of the decompress_inflate.c file from
+boot/compress/misc.c, there are different flush() defines:
+
+In file included from arch/arm/boot/compressed/misc.c:249:
+arch/arm/boot/compressed/../../../../lib/decompress_inflate.c:138:29: error: macro "flush" passed 2 arguments, but takes just 0
+
+Fix this by removing the define of flush() in misc.c for
+CONFIG_DEBUG_ICEDCC as it's already defined in mach/uncompress.h,
+and that is being included unconditionally.
+
+Also use a static inline function instead of define
+for mach-mxc and mach-gemini to avoid similar bug
+for those platforms.

++ If you need code which can detect and parse these tables, and

++ * have one of the subtle syntax dependencies: an individual BRANCH (as
++ * opposed to a collection of them) is never concatenated with anything
++ * because of operator precedence.) The operand of some types of node is
++ * a literal string; for others, it is a node leading into a sub-FSM. In
++ * particular, the operand of a BRANCH node is the first node of the branch.

++ * Authors: Patrick McHardy, <kaber@trash.net>
++ *
++ * The first version was written by Martin Devera, <devik@cdi.cz>
++ *
++ * Credits: Jan Rafaj <imq2t@cedric.vabo.cz>
++ * - Update patch to 2.4.21
++ * Sebastian Strollo <sstrollo@nortelnetworks.com>
++ * - Fix "Dead-loop on netdevice imq"-issue
++ * Marcel Sebek <sebek64@post.cz>
++ * - Update to 2.6.2-rc1
++ *
++ * After some time of inactivity there is a group taking care
++ * of IMQ again: http://www.linuximq.net
++ *
++ *
++ * 2004/06/30 - New version of IMQ patch to kernels <=2.6.7
++ * including the following changes:
++ *
++ * - Correction of ipv6 support "+"s issue (Hasso Tepper)
++ * - Correction of imq_init_devs() issue that resulted in
++ * kernel OOPS unloading IMQ as module (Norbert Buchmuller)
++ * - Addition of functionality to choose number of IMQ devices
++ * during kernel config (Andre Correa)
++ * - Addition of functionality to choose how IMQ hooks on
++ * PRE and POSTROUTING (after or before NAT) (Andre Correa)
++ * - Cosmetic corrections (Norbert Buchmuller) (Andre Correa)
++ *
++ *
++ * 2005/12/16 - IMQ versions between 2.6.7 and 2.6.13 were
++ * released with almost no problems. 2.6.14-x was released
++ * with some important changes: nfcache was removed; After
++ * some weeks of trouble we figured out that some IMQ fields
++ * in skb were missing in skbuff.c - skb_clone and copy_skb_header.
++ * These functions are correctly patched by this new patch version.
++ *
++ * Thanks for all who helped to figure out all the problems with
++ * 2.6.14.x: Patrick McHardy, Rune Kock, VeNoMouS, Max CtRiX,
++ * Kevin Shanahan, Richard Lucassen, Valery Dachev (hopefully
++ * I didn't forget anybody). I apologize again for my lack of time.
++ *
++ *
++ * 2008/06/17 - 2.6.25 - Changed imq.c to use qdisc_run() instead
++ * of qdisc_restart() and moved qdisc_run() to tasklet to avoid
++ * recursive locking. New initialization routines to fix 'rmmod' not
++ * working anymore. Used code from ifb.c. (Jussi Kivilinna)
++ *
++ * 2008/08/06 - 2.6.26 - (JK)
++ * - Replaced tasklet with 'netif_schedule()'.
++ * - Cleaned up and added comments for imq_nf_queue().
++ *
++ * 2009/04/12
++ * - Add skb_save_cb/skb_restore_cb helper functions for backuping
++ * control buffer. This is needed because qdisc-layer on kernels
++ * 2.6.27 and newer overwrite control buffer. (Jussi Kivilinna)
++ * - Add better locking for IMQ device. Hopefully this will solve
++ * SMP issues. (Jussi Kivilinna)
++ * - Port to 2.6.27
++ * - Port to 2.6.28
++ * - Port to 2.6.29 + fix rmmod not working
++ *
++ * 2009/04/20 - (Jussi Kivilinna)
++ * - Use netdevice feature flags to avoid extra packet handling
++ * by core networking layer and possibly increase performance.
++ *
++ * 2009/09/26 - (Jussi Kivilinna)
++ * - Add imq_nf_reinject_lockless to fix deadlock with
++ * imq_nf_queue/imq_nf_reinject.
++ *
++ * 2009/12/08 - (Jussi Kivilinna)
++ * - Port to 2.6.32
++ * - Add check for skb->nf_queue_entry==NULL in imq_dev_xmit()
++ * - Also add better error checking for skb->nf_queue_entry usage
++ *
++ * Also, many thanks to pablo Sebastian Greco for making the initial
++ * patch and to those who helped the testing.
++ *
++ * More info at: http://www.linuximq.net/ (Andre Correa)

++
++ This is an enchanced SFQ version which allows you to control some
++ hardcoded values in the SFQ scheduler.
++
++ ESFQ also adds control of the hash function used to identify packet

++ minixfs or pramfs.
++
++2005-06-30 Eric Lammerts <eric@lammerts.org>
++
++ * fix for an oops when overwriting a binary thats beeing

++
++2005-06-09 <mk@mary>
++
++ * Renamed overlay to mini_fo-overlay.
++
++ * Added mini_fo-merge script to allow merging of storage and base
++ after making modifications.
++
++2005-05-22 root <mk@mary>
++
++ * Added overlay script that allows to easily mount mini_fo ontop
++ of a given base directory
++
++2005-05-10 <mk@mary>
++
++ * inode.c: xattr functions return -EOPNOSUPP instead of
++ -ENOSUPP, what confuses "ls -l"
++
++ * Changed license from LGPL to GPL.
++
++2005-05-08 root <mk@mary>
++
++ * Makefile: clean it up and added make install and make
++ uninstall.
++
++2005-05-06 <mk@mary>
++
++ * merged devel branch back to main. [v0-6-0-pre3]
++
++ * removed unused files print.c and fist_ioctl. [devel-0-0-18]
++
++ * ioctl: removed fist_ioctl stuff, that is not needed for
++ now.
++
++2005-05-03 <mk@mary>
++
++ * file.c: simplified mini_fo_open and mini_fo_setattr using
++ new state changing functions. [devel-0-0-17]
++
++ * inode.c: Fixed getattr state bug (see below) in 2.4 function
++ mini_fo_inode revalidate.
++
++ * inode.c: found an other bug in mini_fo_getattr. States are not
++ reliable in this function, as a file can be opened, unlinked and
++ the getattr function called. This results in a deleted dentry
++ with an inode. Fix is to ignore states and simply use the inode
++ available.
++
++2005-04-29 <mk@mary>
++
++ * file.c: Bugfix and cleanup in fasync and fsync. [devel-0-0-16]
++
++ * file.c: do not use mini_fo_lock so the generic version is
++ used (I guess).
++
++ * inode.c: getattr, never call getattr on lower files, as this
++ will cause the inum to change.
++
++ * inode.c: rename_reg_file renamed to rename_nondir, as it
++ doesn't matter as long it't not a dir. Removed all
++ rename_dev_file etc.
++
++ * tagged as devel-0-0-15
++
++ * inode.c: added support for chosing support for extended
++ attrs at compile time by XATTR define in mini_fo.h .
++
++ * inode.c: fixed mini_fo_getattr to use mini_fo inode and not
++ lower again, what avoids inode number changes that confused
++ rm again. This is the proper solution.
++
++2005-04-24 <mk@mary>
++
++ * all files: updated Copyright notive to 2005. [devel-0-0-14]
++
++ * inode.c: fixed mini_fo_getattr to not change the inode
++ number, even if lower files change.
++
++ * super.c: fixed a bug that caused deleted base file to show
++ up suddenly after some time, or after creating a special
++ file. The problem was that after some time or after special
++ file creating sync_sb_inodes is called by the vfs, that
++ called our mini_fo_put_inode. There was (wrongly) called
++ __meta_put_lists, that nuked the lists, although the inode
++ was going to continue its life. Moving __meta_put_lists to
++ mini_fo_clear_inode, where an inode is really destroyed,
++ solved the problem.
++
++
++2005-04-23 <mk@mary>
++
++ * state.c, aux.c: more cleaning up and
++ simplifications. [devel-0-0-13]
++
++ * inode.c: implemented mini_fo_getattr, that was required for
++ 2.6 because inode_revalidate has been remove there, and the
++ old "du" bug returned.
++
++
++2005-04-20 <mk@mary>
++
++ * aux.c: get_neg_sto_dentry(): allow to be called for dentries
++ in state UNMODIFIED, NON_EXISTANT _and_ DELETED.
++
++2005-04-19 <mk@mary>
++
++ * Fixed a bug under 2.6 that caused files deleted via mini_fo
++ not to be deleted properly and therefore the fs filled up
++ untill no memory was left. [devel-0-0-12]
++
++ * Added basic hard link support. This means that creating
++ hardlinks will work, but existing ones will be treated as
++ individual files. [devel-0-0-11]
++
++2005-04-17 <mk@mary>
++
++ * Bugfixes
++
++2005-04-13 root <mk@mary>
++
++ * Added file state.c for the state transition
++ functions. Doesn't work very well yet, though...
++
++2005-04-12 <mk@mary>
++
++ * Porting to 2.6 started, which is easier than expected, also
++ due to Olivier previous work.
++
++2005-04-08 <mk@mary>
++
++ * Fixed the bug that caused du to return invalid sizes of
++ directory trees. The problem was that
++ mini_fo_inode_revalidate didn't always copy the attributes
++ from the base inode properly.
++
++2005-04-01 Markus Klotzbuecher <mk@chasey>
++
++ * Merged devel branch back to main trunk and updated the
++ RELEASE notes. This will be 0-6-0-pre1.
++
++2005-03-31 Markus Klotzbuecher <mk@chasey>
++
++ * Fixed some bugs in rename_reg_file, that only showed up in
++ the kernel compile test. Kernel compiles cleanly ontop of
++ mini_fo, now also make mrproper etc. work. Seems pretty stable.
++
++2005-03-28 Markus Klotzbuecher <mk@chasey>
++
++ * Many, many directory renaming bugfixes and a lot of other
++ cleanup. Dir renaming seems to work relatively stable.
++
++2005-03-22 Markus Klotzbuecher <mk@chasey>
++
++ * Finished implementing lightweight directory renaming. Some
++ basic testing indicates it works fine.
++ Next is to implement testcases for the testsuite and confirm
++ everything is really working ok.
++
++2005-03-18 Markus Klotzbuecher <mk@chasey>
++
++ * Finished implementing meta.c stuff required for directory
++ renaming.
++
++2005-03-17 Markus Klotzbuecher <mk@chasey>
++
++ * Fixed all compile warnings + an extremly old bug that
++ somehow crept in while reworking the wol stuff to the META
++ system. Turning on -Werror again... :-)
++
++ * Fixed some bugs in the new rename_reg_file function.
++
++ * Rewrote mini_fo rename and split it into several
++ subfunctions, that handle the different types
++ seperately. Rewrote the regular file function aswell, as it
++ was implemented somewhat inefficient.
++
++2005-03-16 Markus Klotzbuecher <mk@chasey>
++
++ * Implemented new META subsystem, removed old WOL stuff in favor
++ if it.
++
++ * After some basic testing everything seems ok...
++
++2005-03-11 Markus Klotzbuecher <mk@chasey>
++
++ * Renaming a non regular file caused trouble because I always
++ tried to copy the contents. Now I only do this for regular
++ files. mini_fo_rename still isn't implemented properly, renaming
++ of device files, symlinks etc. results in a empty regular file
++ instead of the proper type.
++
++ * Directory renaming suddenly works! What a surprise! I guess
++ this is because renaming is implemented as making a copy and
++ removing the original. Still this might not work
++ everywhere...
++
++2005-03-09 Markus Klotzbuecher <mk@chasey>
++
++ * Bugfix, when a mini_fo directory that exists in storage
++ (state: MODIFIED, CREATED and DEL_REWRITTEN) is deleted, a
++ possibly existing WOL file contained in it needs to be
++ deleted too.
++
++ * Starting cleanup: defined state names in order to get rid of
++ the state numbers.
++
++2005-03-08 Markus Klotzbuecher <mk@chasey>
++
++ * Makefile fix, fist_ioctl was built against wrong sources if ARCH=um
++
++ * Fixed a bug in dentry.c, mini_fo_d_hash. In state 4 =
++ DEL_REWRITTEN the hash was calculated from the base dentry,
++ which was wrong and and caused assertions in
++ __mini_fo_hidden_dentry to fail.
++
++2005-02-21 <mk@mary>
++
++ * Implemented directory deleting (inode.c)
++
++ * main.c: made mini_fo_parse_options a little more robust.
++
++2004-12-22 <mk@mary>
++
++ * Makefile cleanup and uml stuff, removed unneccessary files
++
++ * Created a new and hopefully more informative README
++
++ * CHANGELOG: created a new CHANGELOG and added old entries reversely
++
++
++2004-10-24 Gleb Natapov <gleb@nbase.co.il>
++
++ * Fix: owner and group where not correctly copied from base to
++ storage.
++
++
++2004-10-05 Gleb Natapov <gleb@nbase.co.il>
++
++ * Implementation of fsync, fasync and lock mini_fo functions.
++
++
++2004-09-29 Bob Lee <bob@pantasys.com>
++
++ * Fix of a serious pointer bug
++
++
++2004-09-28 Gleb Natapov <gleb@nbase.co.il>
++
++ * Implementation of mini_fo_mknod and mini_fo_rename, support
++ for device files.

++README for the mini_fo overlay file system
++=========================================
++
++
++WHAT IS MINI_FO?
++----------------
++
++mini_fo is a virtual kernel file system that can make read-only
++file systems writable. This is done by redirecting modifying operations
++to a writeable location called "storage directory", and leaving the
++original data in the "base directory" untouched. When reading, the
++file system merges the modifed and original data so that only the
++newest versions will appear. This occurs transparently to the user,
++who can access the data like on any other read-write file system.
++
++Base and storage directories may be located on the same or on
++different partitions and may be of different file system types. While
++the storage directory obviously needs to be writable, the base may or
++may not be writable, what doesn't matter as it will no be modified
++anyway.
++
++
++WHAT IS GOOD FOR?
++-----------------
++
++The primary purpose of the mini_fo file system is to allow easy
++software updates to embedded systems, that often store their root
++file system in a read-only flash file system, but there are many
++more as for example sandboxing, or for allowing live-cds to
++permanently store information.
++
++
++BUILDING
++--------
++This should be simple. Adjust the Makefile to point to the correct
++kernel headers you want to build the module for. Then:
++
++ # make
++
++should build "mini_fo.o" for a 2.4 kernel or "mini_fo.ko" for a 2.6
++kernel.
++
++If you are building the module for you current kernel, you can install
++the module (as root):
++
++ # make install
++
++or uninstall with
++
++ # make uninstall
++
++
++USING THE FILE SYSTEM
++--------------------
++
++the general mount syntax is:
++
++ mount -t mini_fo -o base=<base directory>,sto=<storage directory>\
++ <base directory> <mount point>
++
++Example:
++
++You have mounted a cdrom to /mnt/cdrom and want to modifiy some files
++on it:
++
++load the module (as root)
++
++ # insmod mini_fo.o for a 2.4 kernel or
++
++ # insmod mini_fo.ko for a 2.6 kernel
++
++
++create a storage dir in tmp and a mountpoint for mini_fo:
++
++ # mkdir /tmp/sto
++ # mkdir /mnt/mini_fo
++
++and mount the mini_fo file system:
++
++ # mount -t mini_fo -o base=/mnt/cdrom,sto=/tmp/sto /mnt/cdrom /mnt/mini_fo
++
++
++Now the data stored on the cd can be accessed via the mini_fo
++mountpoint just like any read-write file system, files can be modified
++and deleted, new ones can be created and so on. When done unmount the
++file system:
++
++ # unmount /mnt/mini_fo
++
++Note that if the file system is mounted again using the same storage
++file system, of course it will appear in the modified state again. If
++you remount it using an new empty storage directory, it will be
++unmodified. Therefore by executing:
++
++ # cd /tmp/sto
++ # rm -rf *
++
++you can nuke all the changes you made to the original file system. But
++ remember NEVER do this while the mini_fo file system is mounted!
++
++
++Alternatively you can use the mini_fo-overlay bash script, that
++simplifies managing mini_fo mounts. See TOOLS Section.
++
++
++TOOLS
++-----
++
++mini_fo-merge (experimental):
++
++This is a bash script that will merge changes contained in the storage
++directory back to the base directory. This allows mini_fo to function
++as a cache file system by overlaying a slow (network, ...) file system
++and using a fast (ramdisk, ...) as storage. When done, changes can be
++merged back to the (slow) base with mini_fo-merge. See "mini_fo-merge
++-h" for details.
++
++It can be usefull for merging changes back after a successfull test
++(patches, software updates...)
++
++
++mini_fo-overlay:
++
++This bash script simplifies managing one or more mini_fo mounts. For
++overlaying a directory called "basedir1", you can just call:
++
++ # mini_fo-overlay basedir1
++
++This will mount mini_fo with "basedir1" as base, "/tmp/sto-basedir1/"
++as storage to "/mnt/mini_fo-basedir1/". It has more options though,
++type "mini_fo-overlay -h" for details.

++DOCUMENTATION, REPORTING BUGS, GETTING HELP
++-------------------------------------------
++
++Please visit the mini_fo project page at:
++
++http://www.denx.de/twiki/bin/view/Know/MiniFOHome
++
++
++WARNINGS
++--------
++
++Never modify the base or the storage directorys while the mini_fo
++file system is mounted, or you might crash you system. Simply accessing
++and reading should not cause any trouble.
++
++Exporting a mini_fo mount point via NFS has not been tested, and may
++or may not work.
++
++Check the RELEASE_NOTES for details on bugs and features.

++Release: mini_fo-0.6.1 (v0-6-1)
++Date: 21.09.2005
++
++
++Changes:
++--------
++v0-6-1:
++
++- bugfixes (see ChangeLog)
++
++- two helper scripts "mini_fo_merge" and "mini_fo_overlay" (see
++ README for details).
++
++v0-6-0:
++
++- Support for 2.4 and 2.6 (see Makefile)
++
++- Partial hard link support (creating works as expected, but already
++ existing links in the base file system will be treated as if they
++ were individual files).
++
++- Various bugfixes and cleanups.
++
++
++v0-6-0-pre1:
++
++- This is mini_fo-0-6-0-pre1! This release is a complete rewrite of
++ many vital mini_fo parts such as the old whiteout list code which
++ has been replaced by the new META subsystem.
++
++- Light weight directory renaming implemented. This means if a
++ directory is renamed via the mini_fo filesystem this will no longer
++ result in a complete copy in storage, instead only one empty
++ directory will be created. All base filed contained in the original
++ directory stay there until modified.
++
++- Special files (creating, renaming, deleting etc.) now working.
++
++- Many bugfixes and cleanup, mini_fo is now a lot more stable.
++
++
++v0-5-10:
++
++- Final release of the 0-5-* versions. Next will be a complete rewrite
++ of many features. This release contains several bugfixes related to
++ directory renaming.
++
++
++v0-5-10-pre6:
++
++- Lots of cleanup and several bugfixes related to directory deleting
++
++- Directory renaming suddenly works, what is most likely due to the
++ fact tha that "mv" is smart: if the classic rename doesn't work it
++ will assume that source and target file are on different fs and will
++ copy the directory and try to remove the source directory. Until
++ directory removing wasn't implemented, it would fail to do this and
++ rollback.
++ So, directory renaming works for now, but it doesn't yet do what you
++ would expect from a overlay fs, so use with care.
++
++
++v0-5-10-pre5:
++
++- implemented directory deleting
++- made parsing of mount options more stable
++- New format of mount options! (See README)
++- I can't reproduce the unknown panic with 2.4.25 anymore, so I'll
++ happily assume it never existed!
++
++
++Implemented features:
++---------------------
++
++- creating hard links (see BUGS on already existing hard links)
++- lightweight directory renaming
++- renaming device files, pipes, sockets, etc.
++- creating, renaming, deleting of special files
++- deleting directorys
++- general directory reading (simple "ls" )
++- creating files in existing directorys
++- creating directorys
++- renaming files.
++- reading and writing files (involves opening)
++- appending to files (creates copy in storage)
++- deleting files
++- llseek works too, what allows editors to work
++- persistency (a deleted file stay deleted over remounts)
++- use of symbolic links
++- creating of device files
++
++
++Not (yet) implemented features:
++-------------------------------
++
++- full hard link support.
++
++
++
++BUGS:
++-----
++
++Hard links in the base file system will be treated as individual
++files, not as links to one inode.
++
++The main problem with hard links isn't allowing to create them, but
++their pure existence. If you modify a base hard link, the changes made
++will only show up on this link, the other link will remain in the
++original state. I hope to fix this someday. Please note that this does
++not effect the special hard links '.' and '..', that are handled
++seperately by the lower fs.

+- Give the number of Blocks to reserve for checkpointing.
+- Checkpointing saves the state at unmount so that mounting is
+- much faster as a scan of all the flash to regenerate this state
+- is not needed. These Blocks are reserved per partition, so if
+- you have very small partitions the default (10) may be a mess
+- for you. You can set this value to 0, but that does not mean
+- checkpointing is disabled at all. There only won't be any
+- specially reserved blocks for checkpointing, so if there is
+- enough free space on the filesystem, it will be used for
+- checkpointing.
+-
+- If unsure, leave at default (10), but don't wonder if there are
+- always 2MB used on your large page device partition (10 x 2k
+- pagesize). When using small partitions or when being very small
+- on space, you probably want to set this to zero.

+Author: chas williams - CONTRACTOR <chas@cmf.nrl.navy.mil>
+Date: Fri Dec 4 11:06:32 2009 +0000
+
+ atm: [br2684] allow routed mode operation again
+
+ in routed mode, we don't have a hardware address so netdev_ops doesnt
+ need to validate our hardware address via .ndo_validate_addr

++GPIOMMC - Driver for an MMC/SD card on a bitbanging GPIO SPI bus
++================================================================
++
++The gpiommc module hooks up the mmc_spi and spi_gpio modules for running an
++MMC or SD card on GPIO pins.
++
++Two interfaces for registering a new MMC/SD card device are provided:
++A static platform-device based mechanism and a dynamic configfs based interface.
++
++
++Registering devices via platform-device
++=======================================
++
++The platform-device interface is used for registering MMC/SD devices that are
++part of the hardware platform. This is most useful only for embedded machines
++with MMC/SD devices statically connected to the platform GPIO bus.
++
++The data structures are declared in <linux/mmc/gpiommc.h>.
++
++To register a new device, define an instance of struct gpiommc_platform_data.
++This structure holds any information about how the device is hooked up to the
++GPIO pins and what hardware modes the device supports. See the docbook-style
++documentation in the header file for more information on the struct fields.
++
++Then allocate a new instance of a platform device by doing:
++
++ pdev = platform_device_alloc(GPIOMMC_PLATDEV_NAME, gpiommc_next_id());
++
++This will allocate the platform device data structures and hook it up to the
++gpiommc driver.
++Then add the gpiommc_platform_data to the platform device.
++
++ err = platform_device_add_data(pdev, pdata, sizeof(struct gpiommc_platform_data));
++
++You may free the local instance of struct gpiommc_platform_data now. (So the
++struct may be allocated on the stack, too).
++Now simply register the platform device.
++
++ err = platform_device_add(pdev);
++
++Done. The gpiommc probe routine will be invoked now and you should see a kernel
++log message for the added device.
++
++
++Registering devices via configfs
++================================
++
++MMC/SD cards connected via GPIO often are a pretty dynamic thing, as for example
++selfmade hacks for soldering an MMC/SD card to standard GPIO pins on embedded
++hardware are a common situation.
++So we provide a dynamic interface to conveniently handle adding and removing
++devices from userspace, without the need to recompile the kernel.
++
++The "gpiommc" subdirectory at the configfs mountpoint is used for handling
++the dynamic configuration.
++
++To create a new device, it must first be allocated with mkdir.
++The following command will allocate a device named "my_mmc":
++ mkdir /config/gpiommc/my_mmc
++
++There are several configuration files available in the new
++/config/gpiommc/my_mmc/ directory:
++
++gpio_data_in = The SPI data-IN GPIO pin number.
++gpio_data_out = The SPI data-OUT GPIO pin number.
++gpio_clock = The SPI Clock GPIO pin number.
++gpio_chipselect = The SPI Chipselect GPIO pin number.
++gpio_chipselect_activelow = Boolean. If 0, Chipselect is active-HIGH.
++ If 1, Chipselect is active-LOW.
++spi_mode = The SPI data mode. Can be 0-3.
++spi_delay = Enable all delays in the lowlevel bitbanging.
++max_bus_speed = The maximum SPI bus speed. In Hertz.
++
++register = Not a configuration parameter.
++ Used to register the configured card
++ with the kernel.
++
++The device must first get configured and then registered by writing "1" to
++the "register" file.
++The configuration parameters "gpio_data_in", "gpio_data_out", "gpio_clock"
++and "gpio_chipselect" are essential and _must_ be configured before writing
++"1" to the "register" file. The registration will fail, otherwise.
++
++The default values for the other parameters are:
++gpio_chipselect_activelow = 1 (CS active-LOW)
++spi_mode = 0 (SPI_MODE_0)
++spi_delay = 1 (enabled)
++max_bus_speed = 5000000 (5 Mhz)
++
++Configuration values can not be changed after registration. To unregister
++the device, write a "0" to the "register" file. The configuration can be
++changed again after unregistering.
++
++To completely remove the device, simply rmdir the directory
++(/config/gpiommc/my_mmc in this example).
++There's no need to first unregister the device before removing it. That will
++be done automatically.

+From: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp>
+
+Add dma_dev, a pointer to struct device, to struct ssb_device. We pass it
+to the generic DMA API with SSB_BUSTYPE_PCI and SSB_BUSTYPE_SSB.
+ssb_devices_register() sets up it properly.
+
+This is preparation for replacing the ssb bus specific DMA API (ssb_dma_*)
+with the generic DMA API.

+Subject: [PATCH] Squashfs: add decompressor entries for lzma and lzo
+
+Add knowledge of lzma/lzo compression formats to the decompressor
+framework. For now these are added as unsupported. Without
+these entries lzma/lzo compressed filesystems will be flagged as
+having unknown compression which is undesirable.

+
+Add a config option DECOMPRESS_LZMA_NEEDED which allows subsystems to
+specify they need the unlzma code. Normally decompress_unlzma.c is
+compiled with __init and unlzma is not exported to modules.

+This patch allows turning off the in-kernel Algorithmics
+FPU emulator support, which allows one to save a couple of
+precious blocks on an embedded system.

+GCC 4.4.x looks to be adding support for generating out-of-line register
+saves/restores based on:
+
+http://gcc.gnu.org/ml/gcc-patches/2008-04/msg01678.html
+
+This breaks the kernel build as we'd have to link with libgcc to get the
+implementation of the register save/restores.
+
+To workaround this issue, we just stole the save/restore code from gcc
+and simplified it down for our needs (integer only). We only do this if
+PPC32 as gcc makes believe the linker on ppc64 will deal with this and
+only if CONFIG_CC_OPTIMIZE_FOR_SIZE is set (thus -Os).
+
+Signed-off-by: Kumar Gala <[EMAIL PROTECTED]>
+---
+
+If someone using cutting edge toolchains for ppc64 could test and make
+sure if we enable CONFIG_CC_OPTIMIZE_FOR_SIZE things work that would be
+nice.

++ MyLoader is a bootloader which allows the user to define partitions
++ in flash devices, by putting a table in the second erase block
++ on the device, similar to a partition table. This table gives the

++
++ If you need code which can detect and parse these tables, and
++ register MTD 'partitions' corresponding to each image detected,
++ enable this option.
++
++ You will still need the parsing functions to be called by the driver
++ for your particular device. It won't happen automatically.

++ *
++ * Authors: Patrick McHardy, <kaber@trash.net>
++ *
++ * The first version was written by Martin Devera, <devik@cdi.cz>
++ *
++ * Credits: Jan Rafaj <imq2t@cedric.vabo.cz>
++ * - Update patch to 2.4.21
++ * Sebastian Strollo <sstrollo@nortelnetworks.com>
++ * - Fix "Dead-loop on netdevice imq"-issue
++ * Marcel Sebek <sebek64@post.cz>
++ * - Update to 2.6.2-rc1
++ *
++ * After some time of inactivity there is a group taking care
++ * of IMQ again: http://www.linuximq.net
++ *
++ *
++ * 2004/06/30 - New version of IMQ patch to kernels <=2.6.7
++ * including the following changes:
++ *
++ * - Correction of ipv6 support "+"s issue (Hasso Tepper)
++ * - Correction of imq_init_devs() issue that resulted in
++ * kernel OOPS unloading IMQ as module (Norbert Buchmuller)
++ * - Addition of functionality to choose number of IMQ devices
++ * during kernel config (Andre Correa)
++ * - Addition of functionality to choose how IMQ hooks on
++ * PRE and POSTROUTING (after or before NAT) (Andre Correa)
++ * - Cosmetic corrections (Norbert Buchmuller) (Andre Correa)
++ *
++ *
++ * 2005/12/16 - IMQ versions between 2.6.7 and 2.6.13 were
++ * released with almost no problems. 2.6.14-x was released
++ * with some important changes: nfcache was removed; After
++ * some weeks of trouble we figured out that some IMQ fields
++ * in skb were missing in skbuff.c - skb_clone and copy_skb_header.
++ * These functions are correctly patched by this new patch version.
++ *
++ * Thanks for all who helped to figure out all the problems with
++ * 2.6.14.x: Patrick McHardy, Rune Kock, VeNoMouS, Max CtRiX,
++ * Kevin Shanahan, Richard Lucassen, Valery Dachev (hopefully
++ * I didn't forget anybody). I apologize again for my lack of time.
++ *
++ *
++ * 2008/06/17 - 2.6.25 - Changed imq.c to use qdisc_run() instead
++ * of qdisc_restart() and moved qdisc_run() to tasklet to avoid
++ * recursive locking. New initialization routines to fix 'rmmod' not
++ * working anymore. Used code from ifb.c. (Jussi Kivilinna)
++ *
++ * 2008/08/06 - 2.6.26 - (JK)
++ * - Replaced tasklet with 'netif_schedule()'.
++ * - Cleaned up and added comments for imq_nf_queue().
++ *
++ * 2009/04/12
++ * - Add skb_save_cb/skb_restore_cb helper functions for backuping
++ * control buffer. This is needed because qdisc-layer on kernels
++ * 2.6.27 and newer overwrite control buffer. (Jussi Kivilinna)
++ * - Add better locking for IMQ device. Hopefully this will solve
++ * SMP issues. (Jussi Kivilinna)
++ * - Port to 2.6.27
++ * - Port to 2.6.28
++ * - Port to 2.6.29 + fix rmmod not working
++ *
++ * 2009/04/20 - (Jussi Kivilinna)
++ * - Use netdevice feature flags to avoid extra packet handling
++ * by core networking layer and possibly increase performance.
++ *
++ * 2009/09/26 - (Jussi Kivilinna)
++ * - Add imq_nf_reinject_lockless to fix deadlock with
++ * imq_nf_queue/imq_nf_reinject.
++ *
++ * 2009/12/08 - (Jussi Kivilinna)
++ * - Port to 2.6.32
++ * - Add check for skb->nf_queue_entry==NULL in imq_dev_xmit()
++ * - Also add better error checking for skb->nf_queue_entry usage
++ *
++ * Also, many thanks to pablo Sebastian Greco for making the initial
++ * patch and to those who helped the testing.
++ *

++ CBQ (see the top of <file:net/sched/sch_esfq.c> for details and
++ references to the SFQ algorithm).
++
++ This is an enchanced SFQ version which allows you to control some
++ hardcoded values in the SFQ scheduler.
++
++ ESFQ also adds control of the hash function used to identify packet
++ flows. The original SFQ discipline hashes by connection; ESFQ add
++ several other hashing methods, such as by src IP or by dst IP, which
++ can be more fair to users in some networking situations.
++
++ To compile this code as a module, choose M here: the
++ module will be called sch_esfq.

++ bool "Connection Tracking Hash Types"

++ ---help---
++ Say Y here to enable support for hashing based on netfilter connection
++ tracking information. This is useful for a router that is also using
++ NAT to connect privately-addressed hosts to the Internet. If you want
++ to provide fair distribution of upstream bandwidth, ESFQ must use
++ connection tracking information, since all outgoing packets will share
++ the same source address.

++ * Add tons of ugly ifdefs to Ed L. Cashin's mutex patch to

++
++2006-01-24 Ed L. Cashin <ecashin@coraid.com>
++
++ * Support for the new mutex infrastructure
++ (7892f2f48d165a34b0b8130c8a195dfd807b8cb6)
++
++2005-10-15 Markus Klotzbuecher <mk@localhost.localdomain>
++
++ * Bugfix for a serious memory leak in mini_fo_follow_link.
++
++2005-09-21 Markus Klotzbuecher <mk@mary>
++
++ * new release 0.6.1
++
++ * fix of a compiler warning due to changes in 2.6.13
++
++2005-09-21 Klaus Wenninger <klaus.wenninger@siemens.com>
++
++ * file.c: readdir: fix for a bug that caused directory entries
++ to show up twice when using storage filesystems such as
++ minixfs or pramfs.
++
++2005-06-30 Eric Lammerts <eric@lammerts.org>
++
++ * fix for an oops when overwriting a binary thats beeing
++ executed.
++
++2005-06-09 <mk@mary>
++
++ * Renamed overlay to mini_fo-overlay.
++
++ * Added mini_fo-merge script to allow merging of storage and base
++ after making modifications.
++
++2005-05-22 root <mk@mary>
++
++ * Added overlay script that allows to easily mount mini_fo ontop
++ of a given base directory
++
++2005-05-10 <mk@mary>
++
++ * inode.c: xattr functions return -EOPNOSUPP instead of
++ -ENOSUPP, what confuses "ls -l"
++
++ * Changed license from LGPL to GPL.
++
++2005-05-08 root <mk@mary>
++
++ * Makefile: clean it up and added make install and make
++ uninstall.
++
++2005-05-06 <mk@mary>
++
++ * merged devel branch back to main. [v0-6-0-pre3]
++
++ * removed unused files print.c and fist_ioctl. [devel-0-0-18]
++
++ * ioctl: removed fist_ioctl stuff, that is not needed for
++ now.
++
++2005-05-03 <mk@mary>
++
++ * file.c: simplified mini_fo_open and mini_fo_setattr using
++ new state changing functions. [devel-0-0-17]
++
++ * inode.c: Fixed getattr state bug (see below) in 2.4 function
++ mini_fo_inode revalidate.
++
++ * inode.c: found an other bug in mini_fo_getattr. States are not
++ reliable in this function, as a file can be opened, unlinked and
++ the getattr function called. This results in a deleted dentry
++ with an inode. Fix is to ignore states and simply use the inode
++ available.
++
++2005-04-29 <mk@mary>
++
++ * file.c: Bugfix and cleanup in fasync and fsync. [devel-0-0-16]
++
++ * file.c: do not use mini_fo_lock so the generic version is
++ used (I guess).
++
++ * inode.c: getattr, never call getattr on lower files, as this
++ will cause the inum to change.
++
++ * inode.c: rename_reg_file renamed to rename_nondir, as it
++ doesn't matter as long it't not a dir. Removed all
++ rename_dev_file etc.
++
++ * tagged as devel-0-0-15
++
++ * inode.c: added support for chosing support for extended
++ attrs at compile time by XATTR define in mini_fo.h .
++
++ * inode.c: fixed mini_fo_getattr to use mini_fo inode and not
++ lower again, what avoids inode number changes that confused
++ rm again. This is the proper solution.
++
++2005-04-24 <mk@mary>
++
++ * all files: updated Copyright notive to 2005. [devel-0-0-14]
++
++ * inode.c: fixed mini_fo_getattr to not change the inode
++ number, even if lower files change.
++
++ * super.c: fixed a bug that caused deleted base file to show
++ up suddenly after some time, or after creating a special
++ file. The problem was that after some time or after special
++ file creating sync_sb_inodes is called by the vfs, that
++ called our mini_fo_put_inode. There was (wrongly) called
++ __meta_put_lists, that nuked the lists, although the inode
++ was going to continue its life. Moving __meta_put_lists to
++ mini_fo_clear_inode, where an inode is really destroyed,
++ solved the problem.
++
++
++2005-04-23 <mk@mary>
++
++ * state.c, aux.c: more cleaning up and
++ simplifications. [devel-0-0-13]
++
++ * inode.c: implemented mini_fo_getattr, that was required for
++ 2.6 because inode_revalidate has been remove there, and the
++ old "du" bug returned.
++
++
++2005-04-20 <mk@mary>
++
++ * aux.c: get_neg_sto_dentry(): allow to be called for dentries
++ in state UNMODIFIED, NON_EXISTANT _and_ DELETED.
++
++2005-04-19 <mk@mary>
++
++ * Fixed a bug under 2.6 that caused files deleted via mini_fo
++ not to be deleted properly and therefore the fs filled up
++ untill no memory was left. [devel-0-0-12]
++
++ * Added basic hard link support. This means that creating
++ hardlinks will work, but existing ones will be treated as
++ individual files. [devel-0-0-11]
++
++2005-04-17 <mk@mary>
++
++ * Bugfixes
++
++2005-04-13 root <mk@mary>
++
++ * Added file state.c for the state transition
++ functions. Doesn't work very well yet, though...
++
++2005-04-12 <mk@mary>
++
++ * Porting to 2.6 started, which is easier than expected, also
++ due to Olivier previous work.
++
++2005-04-08 <mk@mary>
++
++ * Fixed the bug that caused du to return invalid sizes of
++ directory trees. The problem was that
++ mini_fo_inode_revalidate didn't always copy the attributes
++ from the base inode properly.
++
++2005-04-01 Markus Klotzbuecher <mk@chasey>
++
++ * Merged devel branch back to main trunk and updated the
++ RELEASE notes. This will be 0-6-0-pre1.
++
++2005-03-31 Markus Klotzbuecher <mk@chasey>
++
++ * Fixed some bugs in rename_reg_file, that only showed up in
++ the kernel compile test. Kernel compiles cleanly ontop of
++ mini_fo, now also make mrproper etc. work. Seems pretty stable.
++
++2005-03-28 Markus Klotzbuecher <mk@chasey>
++
++ * Many, many directory renaming bugfixes and a lot of other
++ cleanup. Dir renaming seems to work relatively stable.
++
++2005-03-22 Markus Klotzbuecher <mk@chasey>
++
++ * Finished implementing lightweight directory renaming. Some
++ basic testing indicates it works fine.
++ Next is to implement testcases for the testsuite and confirm
++ everything is really working ok.
++
++2005-03-18 Markus Klotzbuecher <mk@chasey>
++
++ * Finished implementing meta.c stuff required for directory
++ renaming.
++
++2005-03-17 Markus Klotzbuecher <mk@chasey>
++
++ * Fixed all compile warnings + an extremly old bug that
++ somehow crept in while reworking the wol stuff to the META
++ system. Turning on -Werror again... :-)
++
++ * Fixed some bugs in the new rename_reg_file function.
++
++ * Rewrote mini_fo rename and split it into several
++ subfunctions, that handle the different types
++ seperately. Rewrote the regular file function aswell, as it
++ was implemented somewhat inefficient.
++
++2005-03-16 Markus Klotzbuecher <mk@chasey>
++
++ * Implemented new META subsystem, removed old WOL stuff in favor
++ if it.
++
++ * After some basic testing everything seems ok...
++
++2005-03-11 Markus Klotzbuecher <mk@chasey>
++
++ * Renaming a non regular file caused trouble because I always
++ tried to copy the contents. Now I only do this for regular
++ files. mini_fo_rename still isn't implemented properly, renaming
++ of device files, symlinks etc. results in a empty regular file
++ instead of the proper type.
++
++ * Directory renaming suddenly works! What a surprise! I guess
++ this is because renaming is implemented as making a copy and
++ removing the original. Still this might not work
++ everywhere...
++
++2005-03-09 Markus Klotzbuecher <mk@chasey>
++
++ * Bugfix, when a mini_fo directory that exists in storage
++ (state: MODIFIED, CREATED and DEL_REWRITTEN) is deleted, a
++ possibly existing WOL file contained in it needs to be
++ deleted too.
++
++ * Starting cleanup: defined state names in order to get rid of
++ the state numbers.
++
++2005-03-08 Markus Klotzbuecher <mk@chasey>
++
++ * Makefile fix, fist_ioctl was built against wrong sources if ARCH=um
++
++ * Fixed a bug in dentry.c, mini_fo_d_hash. In state 4 =
++ DEL_REWRITTEN the hash was calculated from the base dentry,
++ which was wrong and and caused assertions in
++ __mini_fo_hidden_dentry to fail.
++
++2005-02-21 <mk@mary>
++
++ * Implemented directory deleting (inode.c)
++
++ * main.c: made mini_fo_parse_options a little more robust.
++
++2004-12-22 <mk@mary>
++
++ * Makefile cleanup and uml stuff, removed unneccessary files
++
++ * Created a new and hopefully more informative README
++
++ * CHANGELOG: created a new CHANGELOG and added old entries reversely
++
++
++2004-10-24 Gleb Natapov <gleb@nbase.co.il>
++
++ * Fix: owner and group where not correctly copied from base to
++ storage.
++
++
++2004-10-05 Gleb Natapov <gleb@nbase.co.il>
++
++ * Implementation of fsync, fasync and lock mini_fo functions.
++
++
++2004-09-29 Bob Lee <bob@pantasys.com>
++
++ * Fix of a serious pointer bug
++
++
++2004-09-28 Gleb Natapov <gleb@nbase.co.il>
++
++ * Implementation of mini_fo_mknod and mini_fo_rename, support
++ for device files.

++README for the mini_fo overlay file system
++=========================================
++
++
++WHAT IS MINI_FO?
++----------------
++
++mini_fo is a virtual kernel file system that can make read-only
++file systems writable. This is done by redirecting modifying operations
++to a writeable location called "storage directory", and leaving the
++original data in the "base directory" untouched. When reading, the
++file system merges the modifed and original data so that only the
++newest versions will appear. This occurs transparently to the user,
++who can access the data like on any other read-write file system.
++
++Base and storage directories may be located on the same or on
++different partitions and may be of different file system types. While
++the storage directory obviously needs to be writable, the base may or
++may not be writable, what doesn't matter as it will no be modified
++anyway.
++
++
++WHAT IS GOOD FOR?
++-----------------
++
++The primary purpose of the mini_fo file system is to allow easy
++software updates to embedded systems, that often store their root
++file system in a read-only flash file system, but there are many
++more as for example sandboxing, or for allowing live-cds to
++permanently store information.
++
++
++BUILDING
++--------
++This should be simple. Adjust the Makefile to point to the correct
++kernel headers you want to build the module for. Then:
++
++ # make
++
++should build "mini_fo.o" for a 2.4 kernel or "mini_fo.ko" for a 2.6
++kernel.
++
++If you are building the module for you current kernel, you can install
++the module (as root):
++
++ # make install
++
++or uninstall with
++
++ # make uninstall
++
++
++USING THE FILE SYSTEM
++--------------------
++
++the general mount syntax is:
++
++ mount -t mini_fo -o base=<base directory>,sto=<storage directory>\
++ <base directory> <mount point>
++
++Example:
++
++You have mounted a cdrom to /mnt/cdrom and want to modifiy some files
++on it:
++
++load the module (as root)
++
++ # insmod mini_fo.o for a 2.4 kernel or
++
++ # insmod mini_fo.ko for a 2.6 kernel
++
++
++create a storage dir in tmp and a mountpoint for mini_fo:
++
++ # mkdir /tmp/sto
++ # mkdir /mnt/mini_fo
++
++and mount the mini_fo file system:
++
++ # mount -t mini_fo -o base=/mnt/cdrom,sto=/tmp/sto /mnt/cdrom /mnt/mini_fo
++
++
++Now the data stored on the cd can be accessed via the mini_fo
++mountpoint just like any read-write file system, files can be modified
++and deleted, new ones can be created and so on. When done unmount the
++file system:
++
++ # unmount /mnt/mini_fo
++
++Note that if the file system is mounted again using the same storage
++file system, of course it will appear in the modified state again. If
++you remount it using an new empty storage directory, it will be
++unmodified. Therefore by executing:
++
++ # cd /tmp/sto
++ # rm -rf *
++
++you can nuke all the changes you made to the original file system. But
++ remember NEVER do this while the mini_fo file system is mounted!
++
++
++Alternatively you can use the mini_fo-overlay bash script, that
++simplifies managing mini_fo mounts. See TOOLS Section.
++
++
++TOOLS
++-----
++
++mini_fo-merge (experimental):
++
++This is a bash script that will merge changes contained in the storage
++directory back to the base directory. This allows mini_fo to function
++as a cache file system by overlaying a slow (network, ...) file system
++and using a fast (ramdisk, ...) as storage. When done, changes can be
++merged back to the (slow) base with mini_fo-merge. See "mini_fo-merge
++-h" for details.
++
++It can be usefull for merging changes back after a successfull test
++(patches, software updates...)
++
++
++mini_fo-overlay:
++
++This bash script simplifies managing one or more mini_fo mounts. For
++overlaying a directory called "basedir1", you can just call:
++
++ # mini_fo-overlay basedir1
++
++This will mount mini_fo with "basedir1" as base, "/tmp/sto-basedir1/"
++as storage to "/mnt/mini_fo-basedir1/". It has more options though,
++type "mini_fo-overlay -h" for details.
++
++
++DOCUMENTATION, REPORTING BUGS, GETTING HELP
++-------------------------------------------
++
++Please visit the mini_fo project page at:
++
++http://www.denx.de/twiki/bin/view/Know/MiniFOHome
++
++
++WARNINGS
++--------
++
++Never modify the base or the storage directorys while the mini_fo
++file system is mounted, or you might crash you system. Simply accessing
++and reading should not cause any trouble.
++
++Exporting a mini_fo mount point via NFS has not been tested, and may
++or may not work.
++
++Check the RELEASE_NOTES for details on bugs and features.

++Release: mini_fo-0.6.1 (v0-6-1)
++Date: 21.09.2005
++
++
++Changes:
++--------
++v0-6-1:
++
++- bugfixes (see ChangeLog)
++
++- two helper scripts "mini_fo_merge" and "mini_fo_overlay" (see
++ README for details).
++
++v0-6-0:
++
++- Support for 2.4 and 2.6 (see Makefile)
++
++- Partial hard link support (creating works as expected, but already
++ existing links in the base file system will be treated as if they
++ were individual files).
++
++- Various bugfixes and cleanups.
++
++
++v0-6-0-pre1:
++
++- This is mini_fo-0-6-0-pre1! This release is a complete rewrite of
++ many vital mini_fo parts such as the old whiteout list code which
++ has been replaced by the new META subsystem.
++
++- Light weight directory renaming implemented. This means if a
++ directory is renamed via the mini_fo filesystem this will no longer
++ result in a complete copy in storage, instead only one empty
++ directory will be created. All base filed contained in the original
++ directory stay there until modified.
++
++- Special files (creating, renaming, deleting etc.) now working.
++
++- Many bugfixes and cleanup, mini_fo is now a lot more stable.
++
++
++v0-5-10:
++
++- Final release of the 0-5-* versions. Next will be a complete rewrite
++ of many features. This release contains several bugfixes related to
++ directory renaming.
++
++
++v0-5-10-pre6:
++
++- Lots of cleanup and several bugfixes related to directory deleting
++
++- Directory renaming suddenly works, what is most likely due to the
++ fact tha that "mv" is smart: if the classic rename doesn't work it
++ will assume that source and target file are on different fs and will
++ copy the directory and try to remove the source directory. Until
++ directory removing wasn't implemented, it would fail to do this and
++ rollback.
++ So, directory renaming works for now, but it doesn't yet do what you
++ would expect from a overlay fs, so use with care.
++
++
++v0-5-10-pre5:
++
++- implemented directory deleting
++- made parsing of mount options more stable
++- New format of mount options! (See README)
++- I can't reproduce the unknown panic with 2.4.25 anymore, so I'll
++ happily assume it never existed!
++
++
++Implemented features:
++---------------------
++
++- creating hard links (see BUGS on already existing hard links)
++- lightweight directory renaming
++- renaming device files, pipes, sockets, etc.
++- creating, renaming, deleting of special files
++- deleting directorys
++- general directory reading (simple "ls" )
++- creating files in existing directorys
++- creating directorys
++- renaming files.
++- reading and writing files (involves opening)
++- appending to files (creates copy in storage)
++- deleting files
++- llseek works too, what allows editors to work
++- persistency (a deleted file stay deleted over remounts)
++- use of symbolic links
++- creating of device files
++
++
++Not (yet) implemented features:
++-------------------------------
++
++- full hard link support.
++
++
++
++BUGS:
++-----
++
++Hard links in the base file system will be treated as individual
++files, not as links to one inode.
++
++The main problem with hard links isn't allowing to create them, but
++their pure existence. If you modify a base hard link, the changes made
++will only show up on this link, the other link will remain in the
++original state. I hope to fix this someday. Please note that this does
++not effect the special hard links '.' and '..', that are handled
++seperately by the lower fs.

+- help
+- Give the number of Blocks to reserve for checkpointing.
+- Checkpointing saves the state at unmount so that mounting is
+- much faster as a scan of all the flash to regenerate this state
+- is not needed. These Blocks are reserved per partition, so if
+- you have very small partitions the default (10) may be a mess
+- for you. You can set this value to 0, but that does not mean
+- checkpointing is disabled at all. There only won't be any
+- specially reserved blocks for checkpointing, so if there is
+- enough free space on the filesystem, it will be used for
+- checkpointing.
+-
+- If unsure, leave at default (10), but don't wonder if there are
+- always 2MB used on your large page device partition (10 x 2k
+- pagesize). When using small partitions or when being very small
+- on space, you probably want to set this to zero.

++GPIOMMC - Driver for an MMC/SD card on a bitbanging GPIO SPI bus
++================================================================
++
++The gpiommc module hooks up the mmc_spi and spi_gpio modules for running an
++MMC or SD card on GPIO pins.
++
++Two interfaces for registering a new MMC/SD card device are provided:
++A static platform-device based mechanism and a dynamic configfs based interface.
++
++
++Registering devices via platform-device
++=======================================
++
++The platform-device interface is used for registering MMC/SD devices that are
++part of the hardware platform. This is most useful only for embedded machines
++with MMC/SD devices statically connected to the platform GPIO bus.
++
++The data structures are declared in <linux/mmc/gpiommc.h>.
++
++To register a new device, define an instance of struct gpiommc_platform_data.
++This structure holds any information about how the device is hooked up to the
++GPIO pins and what hardware modes the device supports. See the docbook-style
++documentation in the header file for more information on the struct fields.
++
++Then allocate a new instance of a platform device by doing:
++
++ pdev = platform_device_alloc(GPIOMMC_PLATDEV_NAME, gpiommc_next_id());
++
++This will allocate the platform device data structures and hook it up to the
++gpiommc driver.
++Then add the gpiommc_platform_data to the platform device.
++
++ err = platform_device_add_data(pdev, pdata, sizeof(struct gpiommc_platform_data));
++
++You may free the local instance of struct gpiommc_platform_data now. (So the
++struct may be allocated on the stack, too).
++Now simply register the platform device.
++
++ err = platform_device_add(pdev);
++
++Done. The gpiommc probe routine will be invoked now and you should see a kernel
++log message for the added device.
++
++
++Registering devices via configfs
++================================
++
++MMC/SD cards connected via GPIO often are a pretty dynamic thing, as for example
++selfmade hacks for soldering an MMC/SD card to standard GPIO pins on embedded
++hardware are a common situation.
++So we provide a dynamic interface to conveniently handle adding and removing
++devices from userspace, without the need to recompile the kernel.
++
++The "gpiommc" subdirectory at the configfs mountpoint is used for handling
++the dynamic configuration.
++
++To create a new device, it must first be allocated with mkdir.
++The following command will allocate a device named "my_mmc":
++ mkdir /config/gpiommc/my_mmc
++
++There are several configuration files available in the new
++/config/gpiommc/my_mmc/ directory:
++
++gpio_data_in = The SPI data-IN GPIO pin number.
++gpio_data_out = The SPI data-OUT GPIO pin number.
++gpio_clock = The SPI Clock GPIO pin number.
++gpio_chipselect = The SPI Chipselect GPIO pin number.
++gpio_chipselect_activelow = Boolean. If 0, Chipselect is active-HIGH.
++ If 1, Chipselect is active-LOW.
++spi_mode = The SPI data mode. Can be 0-3.
++spi_delay = Enable all delays in the lowlevel bitbanging.
++max_bus_speed = The maximum SPI bus speed. In Hertz.
++
++register = Not a configuration parameter.
++ Used to register the configured card
++ with the kernel.
++
++The device must first get configured and then registered by writing "1" to
++the "register" file.
++The configuration parameters "gpio_data_in", "gpio_data_out", "gpio_clock"
++and "gpio_chipselect" are essential and _must_ be configured before writing
++"1" to the "register" file. The registration will fail, otherwise.
++
++The default values for the other parameters are:
++gpio_chipselect_activelow = 1 (CS active-LOW)
++spi_mode = 0 (SPI_MODE_0)
++spi_delay = 1 (enabled)
++max_bus_speed = 5000000 (5 Mhz)
++
++Configuration values can not be changed after registration. To unregister
++the device, write a "0" to the "register" file. The configuration can be
++changed again after unregistering.
++
++To completely remove the device, simply rmdir the directory
++(/config/gpiommc/my_mmc in this example).
++There's no need to first unregister the device before removing it. That will
++be done automatically.

+From: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp>
+
+Add dma_dev, a pointer to struct device, to struct ssb_device. We pass it
+to the generic DMA API with SSB_BUSTYPE_PCI and SSB_BUSTYPE_SSB.
+ssb_devices_register() sets up it properly.
+
+This is preparation for replacing the ssb bus specific DMA API (ssb_dma_*)
+with the generic DMA API.

+Subject: [PATCH] Squashfs: Make unlzma available to non initramfs/initrd code
+
+Add a config option DECOMPRESS_LZMA_NEEDED which allows subsystems to
+specify they need the unlzma code. Normally decompress_unlzma.c is
+compiled with __init and unlzma is not exported to modules.

+GCC 4.4.x looks to be adding support for generating out-of-line register
+saves/restores based on:
+
+http://gcc.gnu.org/ml/gcc-patches/2008-04/msg01678.html
+
+This breaks the kernel build as we'd have to link with libgcc to get the
+implementation of the register save/restores.
+
+To workaround this issue, we just stole the save/restore code from gcc
+and simplified it down for our needs (integer only). We only do this if
+PPC32 as gcc makes believe the linker on ppc64 will deal with this and
+only if CONFIG_CC_OPTIMIZE_FOR_SIZE is set (thus -Os).
+
+Signed-off-by: Kumar Gala <[EMAIL PROTECTED]>
+---
+
+If someone using cutting edge toolchains for ppc64 could test and make
+sure if we enable CONFIG_CC_OPTIMIZE_FOR_SIZE things work that would be
+nice.

++ If you need code which can detect and parse these tables, and

++
++ You will still need the parsing functions to be called by the driver
++ for your particular device. It won't happen automatically.

++ * Structure for regexp "program". This is essentially a linear encoding
++ * of a nondeterministic finite-state machine (aka syntax charts or
++ * "railroad normal form" in parsing technology). Each node is an opcode
++ * plus a "next" pointer, possibly plus an operand. "Next" pointers of
++ * all nodes except BRANCH implement concatenation; a "next" pointer with
++ * a BRANCH on both ends of it is connecting two alternatives. (Here we
++ * have one of the subtle syntax dependencies: an individual BRANCH (as
++ * opposed to a collection of them) is never concatenated with anything
++ * because of operator precedence.) The operand of some types of node is
++ * a literal string; for others, it is a node leading into a sub-FSM. In
++ * particular, the operand of a BRANCH node is the first node of the branch.
++ * (NB this is *not* a tree structure: the tail of the branch connects
++ * to the thing following the set of BRANCHes.) The opcodes are:

++ *
++ * Authors: Patrick McHardy, <kaber@trash.net>
++ *
++ * The first version was written by Martin Devera, <devik@cdi.cz>
++ *
++ * Credits: Jan Rafaj <imq2t@cedric.vabo.cz>
++ * - Update patch to 2.4.21
++ * Sebastian Strollo <sstrollo@nortelnetworks.com>
++ * - Fix "Dead-loop on netdevice imq"-issue
++ * Marcel Sebek <sebek64@post.cz>
++ * - Update to 2.6.2-rc1
++ *
++ * After some time of inactivity there is a group taking care
++ * of IMQ again: http://www.linuximq.net
++ *
++ *
++ * 2004/06/30 - New version of IMQ patch to kernels <=2.6.7
++ * including the following changes:
++ *
++ * - Correction of ipv6 support "+"s issue (Hasso Tepper)
++ * - Correction of imq_init_devs() issue that resulted in
++ * kernel OOPS unloading IMQ as module (Norbert Buchmuller)
++ * - Addition of functionality to choose number of IMQ devices
++ * during kernel config (Andre Correa)
++ * - Addition of functionality to choose how IMQ hooks on
++ * PRE and POSTROUTING (after or before NAT) (Andre Correa)
++ * - Cosmetic corrections (Norbert Buchmuller) (Andre Correa)
++ *
++ *
++ * 2005/12/16 - IMQ versions between 2.6.7 and 2.6.13 were
++ * released with almost no problems. 2.6.14-x was released
++ * with some important changes: nfcache was removed; After
++ * some weeks of trouble we figured out that some IMQ fields
++ * in skb were missing in skbuff.c - skb_clone and copy_skb_header.
++ * These functions are correctly patched by this new patch version.
++ *
++ * Thanks for all who helped to figure out all the problems with
++ * 2.6.14.x: Patrick McHardy, Rune Kock, VeNoMouS, Max CtRiX,
++ * Kevin Shanahan, Richard Lucassen, Valery Dachev (hopefully
++ * I didn't forget anybody). I apologize again for my lack of time.
++ *
++ *
++ * 2008/06/17 - 2.6.25 - Changed imq.c to use qdisc_run() instead
++ * of qdisc_restart() and moved qdisc_run() to tasklet to avoid
++ * recursive locking. New initialization routines to fix 'rmmod' not
++ * working anymore. Used code from ifb.c. (Jussi Kivilinna)
++ *
++ * 2008/08/06 - 2.6.26 - (JK)
++ * - Replaced tasklet with 'netif_schedule()'.
++ * - Cleaned up and added comments for imq_nf_queue().
++ *
++ * 2009/04/12
++ * - Add skb_save_cb/skb_restore_cb helper functions for backuping
++ * control buffer. This is needed because qdisc-layer on kernels
++ * 2.6.27 and newer overwrite control buffer. (Jussi Kivilinna)
++ * - Add better locking for IMQ device. Hopefully this will solve
++ * SMP issues. (Jussi Kivilinna)
++ * - Port to 2.6.27
++ * - Port to 2.6.28
++ * - Port to 2.6.29 + fix rmmod not working
++ *
++ * 2009/04/20 - (Jussi Kivilinna)
++ * - Use netdevice feature flags to avoid extra packet handling
++ * by core networking layer and possibly increase performance.
++ *
++ * 2009/09/26 - (Jussi Kivilinna)
++ * - Add imq_nf_reinject_lockless to fix deadlock with
++ * imq_nf_queue/imq_nf_reinject.
++ *
++ * 2009/12/08 - (Jussi Kivilinna)
++ * - Port to 2.6.32
++ * - Add check for skb->nf_queue_entry==NULL in imq_dev_xmit()
++ * - Also add better error checking for skb->nf_queue_entry usage
++ *
++ * Also, many thanks to pablo Sebastian Greco for making the initial
++ * patch and to those who helped the testing.
++ *
++ * More info at: http://www.linuximq.net/ (Andre Correa)

++ The IMQ device(s) is used as placeholder for QoS queueing
++ disciplines. Every packet entering/leaving the IP stack can be
++ directed through the IMQ device where it's enqueued/dequeued to the

++ * only needs to be set if you have multiple levels of NAT. It should be
++ * set to the external address that the STUN clients detect. Note that in
++ * this case, it will not be possible for clients to use UDP with servers
++ * between the NATs.
++ *
++ * If no destaction is specified, auto is used.

++ Queueing (ESFQ) packet scheduling algorithm for some of your network
++ devices or as a leaf discipline for a classful qdisc such as HTB or
++ CBQ (see the top of <file:net/sched/sch_esfq.c> for details and

++
++ This is an enchanced SFQ version which allows you to control some
++ hardcoded values in the SFQ scheduler.
++
++ ESFQ also adds control of the hash function used to identify packet
++ flows. The original SFQ discipline hashes by connection; ESFQ add
++ several other hashing methods, such as by src IP or by dst IP, which
++ can be more fair to users in some networking situations.

++
++2006-01-24 Ed L. Cashin <ecashin@coraid.com>
++
++ * Support for the new mutex infrastructure
++ (7892f2f48d165a34b0b8130c8a195dfd807b8cb6)

++
++ * Bugfix for a serious memory leak in mini_fo_follow_link.
++
++2005-09-21 Markus Klotzbuecher <mk@mary>
++
++ * new release 0.6.1
++
++ * fix of a compiler warning due to changes in 2.6.13
++
++2005-09-21 Klaus Wenninger <klaus.wenninger@siemens.com>
++
++ * file.c: readdir: fix for a bug that caused directory entries
++ to show up twice when using storage filesystems such as
++ minixfs or pramfs.
++
++2005-06-30 Eric Lammerts <eric@lammerts.org>
++
++ * fix for an oops when overwriting a binary thats beeing
++ executed.
++
++2005-06-09 <mk@mary>
++
++ * Renamed overlay to mini_fo-overlay.
++
++ * Added mini_fo-merge script to allow merging of storage and base
++ after making modifications.
++
++2005-05-22 root <mk@mary>
++
++ * Added overlay script that allows to easily mount mini_fo ontop
++ of a given base directory
++
++2005-05-10 <mk@mary>
++
++ * inode.c: xattr functions return -EOPNOSUPP instead of
++ -ENOSUPP, what confuses "ls -l"
++
++ * Changed license from LGPL to GPL.
++
++2005-05-08 root <mk@mary>
++
++ * Makefile: clean it up and added make install and make
++ uninstall.
++
++2005-05-06 <mk@mary>
++
++ * merged devel branch back to main. [v0-6-0-pre3]
++
++ * removed unused files print.c and fist_ioctl. [devel-0-0-18]
++
++ * ioctl: removed fist_ioctl stuff, that is not needed for
++ now.
++
++2005-05-03 <mk@mary>
++
++ * file.c: simplified mini_fo_open and mini_fo_setattr using
++ new state changing functions. [devel-0-0-17]
++
++ * inode.c: Fixed getattr state bug (see below) in 2.4 function
++ mini_fo_inode revalidate.
++
++ * inode.c: found an other bug in mini_fo_getattr. States are not
++ reliable in this function, as a file can be opened, unlinked and
++ the getattr function called. This results in a deleted dentry
++ with an inode. Fix is to ignore states and simply use the inode
++ available.
++
++2005-04-29 <mk@mary>
++
++ * file.c: Bugfix and cleanup in fasync and fsync. [devel-0-0-16]
++
++ * file.c: do not use mini_fo_lock so the generic version is
++ used (I guess).
++
++ * inode.c: getattr, never call getattr on lower files, as this
++ will cause the inum to change.
++
++ * inode.c: rename_reg_file renamed to rename_nondir, as it
++ doesn't matter as long it't not a dir. Removed all
++ rename_dev_file etc.
++
++ * tagged as devel-0-0-15
++
++ * inode.c: added support for chosing support for extended
++ attrs at compile time by XATTR define in mini_fo.h .
++
++ * inode.c: fixed mini_fo_getattr to use mini_fo inode and not
++ lower again, what avoids inode number changes that confused
++ rm again. This is the proper solution.
++
++2005-04-24 <mk@mary>
++
++ * all files: updated Copyright notive to 2005. [devel-0-0-14]
++
++ * inode.c: fixed mini_fo_getattr to not change the inode
++ number, even if lower files change.
++
++ * super.c: fixed a bug that caused deleted base file to show
++ up suddenly after some time, or after creating a special
++ file. The problem was that after some time or after special
++ file creating sync_sb_inodes is called by the vfs, that
++ called our mini_fo_put_inode. There was (wrongly) called
++ __meta_put_lists, that nuked the lists, although the inode
++ was going to continue its life. Moving __meta_put_lists to
++ mini_fo_clear_inode, where an inode is really destroyed,
++ solved the problem.
++
++
++2005-04-23 <mk@mary>
++
++ * state.c, aux.c: more cleaning up and
++ simplifications. [devel-0-0-13]
++
++ * inode.c: implemented mini_fo_getattr, that was required for
++ 2.6 because inode_revalidate has been remove there, and the
++ old "du" bug returned.
++
++
++2005-04-20 <mk@mary>
++
++ * aux.c: get_neg_sto_dentry(): allow to be called for dentries
++ in state UNMODIFIED, NON_EXISTANT _and_ DELETED.
++
++2005-04-19 <mk@mary>
++
++ * Fixed a bug under 2.6 that caused files deleted via mini_fo
++ not to be deleted properly and therefore the fs filled up
++ untill no memory was left. [devel-0-0-12]
++
++ * Added basic hard link support. This means that creating
++ hardlinks will work, but existing ones will be treated as
++ individual files. [devel-0-0-11]
++
++2005-04-17 <mk@mary>
++
++ * Bugfixes
++
++2005-04-13 root <mk@mary>
++
++ * Added file state.c for the state transition
++ functions. Doesn't work very well yet, though...
++
++2005-04-12 <mk@mary>
++
++ * Porting to 2.6 started, which is easier than expected, also
++ due to Olivier previous work.
++
++2005-04-08 <mk@mary>
++
++ * Fixed the bug that caused du to return invalid sizes of
++ directory trees. The problem was that
++ mini_fo_inode_revalidate didn't always copy the attributes
++ from the base inode properly.
++
++2005-04-01 Markus Klotzbuecher <mk@chasey>
++
++ * Merged devel branch back to main trunk and updated the
++ RELEASE notes. This will be 0-6-0-pre1.
++
++2005-03-31 Markus Klotzbuecher <mk@chasey>
++
++ * Fixed some bugs in rename_reg_file, that only showed up in
++ the kernel compile test. Kernel compiles cleanly ontop of
++ mini_fo, now also make mrproper etc. work. Seems pretty stable.
++
++2005-03-28 Markus Klotzbuecher <mk@chasey>
++
++ * Many, many directory renaming bugfixes and a lot of other
++ cleanup. Dir renaming seems to work relatively stable.
++
++2005-03-22 Markus Klotzbuecher <mk@chasey>
++
++ * Finished implementing lightweight directory renaming. Some
++ basic testing indicates it works fine.
++ Next is to implement testcases for the testsuite and confirm
++ everything is really working ok.
++
++2005-03-18 Markus Klotzbuecher <mk@chasey>
++
++ * Finished implementing meta.c stuff required for directory
++ renaming.
++
++2005-03-17 Markus Klotzbuecher <mk@chasey>
++
++ * Fixed all compile warnings + an extremly old bug that
++ somehow crept in while reworking the wol stuff to the META
++ system. Turning on -Werror again... :-)
++
++ * Fixed some bugs in the new rename_reg_file function.
++
++ * Rewrote mini_fo rename and split it into several
++ subfunctions, that handle the different types
++ seperately. Rewrote the regular file function aswell, as it
++ was implemented somewhat inefficient.
++
++2005-03-16 Markus Klotzbuecher <mk@chasey>
++
++ * Implemented new META subsystem, removed old WOL stuff in favor
++ if it.
++
++ * After some basic testing everything seems ok...
++
++2005-03-11 Markus Klotzbuecher <mk@chasey>
++
++ * Renaming a non regular file caused trouble because I always
++ tried to copy the contents. Now I only do this for regular
++ files. mini_fo_rename still isn't implemented properly, renaming
++ of device files, symlinks etc. results in a empty regular file
++ instead of the proper type.
++
++ * Directory renaming suddenly works! What a surprise! I guess
++ this is because renaming is implemented as making a copy and
++ removing the original. Still this might not work
++ everywhere...
++
++2005-03-09 Markus Klotzbuecher <mk@chasey>
++
++ * Bugfix, when a mini_fo directory that exists in storage
++ (state: MODIFIED, CREATED and DEL_REWRITTEN) is deleted, a
++ possibly existing WOL file contained in it needs to be
++ deleted too.
++
++ * Starting cleanup: defined state names in order to get rid of
++ the state numbers.
++
++2005-03-08 Markus Klotzbuecher <mk@chasey>
++
++ * Makefile fix, fist_ioctl was built against wrong sources if ARCH=um
++
++ * Fixed a bug in dentry.c, mini_fo_d_hash. In state 4 =
++ DEL_REWRITTEN the hash was calculated from the base dentry,
++ which was wrong and and caused assertions in
++ __mini_fo_hidden_dentry to fail.
++
++2005-02-21 <mk@mary>
++
++ * Implemented directory deleting (inode.c)
++
++ * main.c: made mini_fo_parse_options a little more robust.
++
++2004-12-22 <mk@mary>
++
++ * Makefile cleanup and uml stuff, removed unneccessary files
++
++ * Created a new and hopefully more informative README
++
++ * CHANGELOG: created a new CHANGELOG and added old entries reversely
++
++
++2004-10-24 Gleb Natapov <gleb@nbase.co.il>
++
++ * Fix: owner and group where not correctly copied from base to
++ storage.
++
++
++2004-10-05 Gleb Natapov <gleb@nbase.co.il>
++
++ * Implementation of fsync, fasync and lock mini_fo functions.
++
++
++2004-09-29 Bob Lee <bob@pantasys.com>
++
++ * Fix of a serious pointer bug
++
++
++2004-09-28 Gleb Natapov <gleb@nbase.co.il>
++
++ * Implementation of mini_fo_mknod and mini_fo_rename, support
++ for device files.

++README for the mini_fo overlay file system
++=========================================
++
++
++WHAT IS MINI_FO?
++----------------
++
++mini_fo is a virtual kernel file system that can make read-only
++file systems writable. This is done by redirecting modifying operations
++to a writeable location called "storage directory", and leaving the
++original data in the "base directory" untouched. When reading, the
++file system merges the modifed and original data so that only the
++newest versions will appear. This occurs transparently to the user,
++who can access the data like on any other read-write file system.
++
++Base and storage directories may be located on the same or on
++different partitions and may be of different file system types. While
++the storage directory obviously needs to be writable, the base may or
++may not be writable, what doesn't matter as it will no be modified
++anyway.
++
++
++WHAT IS GOOD FOR?
++-----------------
++
++The primary purpose of the mini_fo file system is to allow easy
++software updates to embedded systems, that often store their root
++file system in a read-only flash file system, but there are many
++more as for example sandboxing, or for allowing live-cds to
++permanently store information.
++
++
++BUILDING
++--------
++This should be simple. Adjust the Makefile to point to the correct
++kernel headers you want to build the module for. Then:
++
++ # make
++
++should build "mini_fo.o" for a 2.4 kernel or "mini_fo.ko" for a 2.6
++kernel.
++
++If you are building the module for you current kernel, you can install
++the module (as root):
++
++ # make install
++
++or uninstall with
++
++ # make uninstall
++
++
++USING THE FILE SYSTEM
++--------------------
++
++the general mount syntax is:
++
++ mount -t mini_fo -o base=<base directory>,sto=<storage directory>\
++ <base directory> <mount point>
++
++Example:
++
++You have mounted a cdrom to /mnt/cdrom and want to modifiy some files
++on it:
++
++load the module (as root)
++
++ # insmod mini_fo.o for a 2.4 kernel or
++
++ # insmod mini_fo.ko for a 2.6 kernel
++
++
++create a storage dir in tmp and a mountpoint for mini_fo:
++
++ # mkdir /tmp/sto
++ # mkdir /mnt/mini_fo
++
++and mount the mini_fo file system:
++
++ # mount -t mini_fo -o base=/mnt/cdrom,sto=/tmp/sto /mnt/cdrom /mnt/mini_fo
++
++
++Now the data stored on the cd can be accessed via the mini_fo
++mountpoint just like any read-write file system, files can be modified
++and deleted, new ones can be created and so on. When done unmount the
++file system:
++
++ # unmount /mnt/mini_fo
++
++Note that if the file system is mounted again using the same storage
++file system, of course it will appear in the modified state again. If
++you remount it using an new empty storage directory, it will be
++unmodified. Therefore by executing:
++
++ # cd /tmp/sto
++ # rm -rf *
++
++you can nuke all the changes you made to the original file system. But
++ remember NEVER do this while the mini_fo file system is mounted!
++
++
++Alternatively you can use the mini_fo-overlay bash script, that
++simplifies managing mini_fo mounts. See TOOLS Section.
++
++
++TOOLS
++-----
++
++mini_fo-merge (experimental):
++
++This is a bash script that will merge changes contained in the storage
++directory back to the base directory. This allows mini_fo to function
++as a cache file system by overlaying a slow (network, ...) file system
++and using a fast (ramdisk, ...) as storage. When done, changes can be
++merged back to the (slow) base with mini_fo-merge. See "mini_fo-merge
++-h" for details.
++
++It can be usefull for merging changes back after a successfull test
++(patches, software updates...)
++
++
++mini_fo-overlay:
++
++This bash script simplifies managing one or more mini_fo mounts. For
++overlaying a directory called "basedir1", you can just call:
++
++ # mini_fo-overlay basedir1
++
++This will mount mini_fo with "basedir1" as base, "/tmp/sto-basedir1/"
++as storage to "/mnt/mini_fo-basedir1/". It has more options though,
++type "mini_fo-overlay -h" for details.
++
++
++DOCUMENTATION, REPORTING BUGS, GETTING HELP
++-------------------------------------------
++
++Please visit the mini_fo project page at:
++
++http://www.denx.de/twiki/bin/view/Know/MiniFOHome
++
++
++WARNINGS
++--------
++
++Never modify the base or the storage directorys while the mini_fo
++file system is mounted, or you might crash you system. Simply accessing
++and reading should not cause any trouble.
++
++Exporting a mini_fo mount point via NFS has not been tested, and may
++or may not work.
++
++Check the RELEASE_NOTES for details on bugs and features.

++Release: mini_fo-0.6.1 (v0-6-1)
++Date: 21.09.2005
++
++
++Changes:
++--------
++v0-6-1:
++
++- bugfixes (see ChangeLog)
++
++- two helper scripts "mini_fo_merge" and "mini_fo_overlay" (see
++ README for details).
++
++v0-6-0:
++
++- Support for 2.4 and 2.6 (see Makefile)
++
++- Partial hard link support (creating works as expected, but already
++ existing links in the base file system will be treated as if they
++ were individual files).
++
++- Various bugfixes and cleanups.
++
++
++v0-6-0-pre1:
++
++- This is mini_fo-0-6-0-pre1! This release is a complete rewrite of
++ many vital mini_fo parts such as the old whiteout list code which
++ has been replaced by the new META subsystem.
++
++- Light weight directory renaming implemented. This means if a
++ directory is renamed via the mini_fo filesystem this will no longer
++ result in a complete copy in storage, instead only one empty
++ directory will be created. All base filed contained in the original
++ directory stay there until modified.
++
++- Special files (creating, renaming, deleting etc.) now working.
++
++- Many bugfixes and cleanup, mini_fo is now a lot more stable.
++
++
++v0-5-10:
++
++- Final release of the 0-5-* versions. Next will be a complete rewrite
++ of many features. This release contains several bugfixes related to
++ directory renaming.
++
++
++v0-5-10-pre6:
++
++- Lots of cleanup and several bugfixes related to directory deleting
++
++- Directory renaming suddenly works, what is most likely due to the
++ fact tha that "mv" is smart: if the classic rename doesn't work it
++ will assume that source and target file are on different fs and will
++ copy the directory and try to remove the source directory. Until
++ directory removing wasn't implemented, it would fail to do this and
++ rollback.
++ So, directory renaming works for now, but it doesn't yet do what you
++ would expect from a overlay fs, so use with care.
++
++
++v0-5-10-pre5:
++
++- implemented directory deleting
++- made parsing of mount options more stable
++- New format of mount options! (See README)
++- I can't reproduce the unknown panic with 2.4.25 anymore, so I'll
++ happily assume it never existed!
++
++
++Implemented features:
++---------------------
++
++- creating hard links (see BUGS on already existing hard links)
++- lightweight directory renaming
++- renaming device files, pipes, sockets, etc.
++- creating, renaming, deleting of special files
++- deleting directorys
++- general directory reading (simple "ls" )
++- creating files in existing directorys
++- creating directorys
++- renaming files.
++- reading and writing files (involves opening)
++- appending to files (creates copy in storage)
++- deleting files
++- llseek works too, what allows editors to work
++- persistency (a deleted file stay deleted over remounts)
++- use of symbolic links
++- creating of device files
++
++
++Not (yet) implemented features:
++-------------------------------
++
++- full hard link support.
++
++
++
++BUGS:
++-----
++
++Hard links in the base file system will be treated as individual
++files, not as links to one inode.
++
++The main problem with hard links isn't allowing to create them, but
++their pure existence. If you modify a base hard link, the changes made
++will only show up on this link, the other link will remain in the
++original state. I hope to fix this someday. Please note that this does
++not effect the special hard links '.' and '..', that are handled
++seperately by the lower fs.

+- help
+- Give the number of Blocks to reserve for checkpointing.
+- Checkpointing saves the state at unmount so that mounting is
+- much faster as a scan of all the flash to regenerate this state
+- is not needed. These Blocks are reserved per partition, so if
+- you have very small partitions the default (10) may be a mess
+- for you. You can set this value to 0, but that does not mean
+- checkpointing is disabled at all. There only won't be any
+- specially reserved blocks for checkpointing, so if there is
+- enough free space on the filesystem, it will be used for
+- checkpointing.
+-
+- If unsure, leave at default (10), but don't wonder if there are
+- always 2MB used on your large page device partition (10 x 2k
+- pagesize). When using small partitions or when being very small
+- on space, you probably want to set this to zero.

++GPIOMMC - Driver for an MMC/SD card on a bitbanging GPIO SPI bus
++================================================================
++
++The gpiommc module hooks up the mmc_spi and spi_gpio modules for running an
++MMC or SD card on GPIO pins.
++
++Two interfaces for registering a new MMC/SD card device are provided:
++A static platform-device based mechanism and a dynamic configfs based interface.
++
++
++Registering devices via platform-device
++=======================================
++
++The platform-device interface is used for registering MMC/SD devices that are
++part of the hardware platform. This is most useful only for embedded machines
++with MMC/SD devices statically connected to the platform GPIO bus.
++
++The data structures are declared in <linux/mmc/gpiommc.h>.
++
++To register a new device, define an instance of struct gpiommc_platform_data.
++This structure holds any information about how the device is hooked up to the
++GPIO pins and what hardware modes the device supports. See the docbook-style
++documentation in the header file for more information on the struct fields.
++
++Then allocate a new instance of a platform device by doing:
++
++ pdev = platform_device_alloc(GPIOMMC_PLATDEV_NAME, gpiommc_next_id());
++
++This will allocate the platform device data structures and hook it up to the
++gpiommc driver.
++Then add the gpiommc_platform_data to the platform device.
++
++ err = platform_device_add_data(pdev, pdata, sizeof(struct gpiommc_platform_data));
++
++You may free the local instance of struct gpiommc_platform_data now. (So the
++struct may be allocated on the stack, too).
++Now simply register the platform device.
++
++ err = platform_device_add(pdev);
++
++Done. The gpiommc probe routine will be invoked now and you should see a kernel
++log message for the added device.
++
++
++Registering devices via configfs
++================================
++
++MMC/SD cards connected via GPIO often are a pretty dynamic thing, as for example
++selfmade hacks for soldering an MMC/SD card to standard GPIO pins on embedded
++hardware are a common situation.
++So we provide a dynamic interface to conveniently handle adding and removing
++devices from userspace, without the need to recompile the kernel.
++
++The "gpiommc" subdirectory at the configfs mountpoint is used for handling
++the dynamic configuration.
++
++To create a new device, it must first be allocated with mkdir.
++The following command will allocate a device named "my_mmc":
++ mkdir /config/gpiommc/my_mmc
++
++There are several configuration files available in the new
++/config/gpiommc/my_mmc/ directory:
++
++gpio_data_in = The SPI data-IN GPIO pin number.
++gpio_data_out = The SPI data-OUT GPIO pin number.
++gpio_clock = The SPI Clock GPIO pin number.
++gpio_chipselect = The SPI Chipselect GPIO pin number.
++gpio_chipselect_activelow = Boolean. If 0, Chipselect is active-HIGH.
++ If 1, Chipselect is active-LOW.
++spi_mode = The SPI data mode. Can be 0-3.
++spi_delay = Enable all delays in the lowlevel bitbanging.
++max_bus_speed = The maximum SPI bus speed. In Hertz.
++
++register = Not a configuration parameter.
++ Used to register the configured card
++ with the kernel.
++
++The device must first get configured and then registered by writing "1" to
++the "register" file.
++The configuration parameters "gpio_data_in", "gpio_data_out", "gpio_clock"
++and "gpio_chipselect" are essential and _must_ be configured before writing
++"1" to the "register" file. The registration will fail, otherwise.
++
++The default values for the other parameters are:
++gpio_chipselect_activelow = 1 (CS active-LOW)
++spi_mode = 0 (SPI_MODE_0)
++spi_delay = 1 (enabled)
++max_bus_speed = 5000000 (5 Mhz)
++
++Configuration values can not be changed after registration. To unregister
++the device, write a "0" to the "register" file. The configuration can be
++changed again after unregistering.
++
++To completely remove the device, simply rmdir the directory
++(/config/gpiommc/my_mmc in this example).
++There's no need to first unregister the device before removing it. That will
++be done automatically.

+From: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp>
+
+Add dma_dev, a pointer to struct device, to struct ssb_device. We pass it
+to the generic DMA API with SSB_BUSTYPE_PCI and SSB_BUSTYPE_SSB.
+ssb_devices_register() sets up it properly.
+
+This is preparation for replacing the ssb bus specific DMA API (ssb_dma_*)
+with the generic DMA API.

+Subject: [PATCH] Squashfs: Make unlzma available to non initramfs/initrd code
+
+Add a config option DECOMPRESS_LZMA_NEEDED which allows subsystems to
+specify they need the unlzma code. Normally decompress_unlzma.c is
+compiled with __init and unlzma is not exported to modules.

+MIPS: allow disabling the kernel FPU emulator
+
+This patch allows turning off the in-kernel Algorithmics
+FPU emulator support, which allows one to save a couple of
+precious blocks on an embedded system.

+GCC 4.4.x looks to be adding support for generating out-of-line register
+saves/restores based on:
+
+http://gcc.gnu.org/ml/gcc-patches/2008-04/msg01678.html
+
+This breaks the kernel build as we'd have to link with libgcc to get the
+implementation of the register save/restores.
+
+To workaround this issue, we just stole the save/restore code from gcc
+and simplified it down for our needs (integer only). We only do this if
+PPC32 as gcc makes believe the linker on ppc64 will deal with this and
+only if CONFIG_CC_OPTIMIZE_FOR_SIZE is set (thus -Os).
+
+Signed-off-by: Kumar Gala <[EMAIL PROTECTED]>
+---
+
+If someone using cutting edge toolchains for ppc64 could test and make
+sure if we enable CONFIG_CC_OPTIMIZE_FOR_SIZE things work that would be
+nice.

++ MyLoader is a bootloader which allows the user to define partitions
++ in flash devices, by putting a table in the second erase block
++ on the device, similar to a partition table. This table gives the
++ offsets and lengths of the user defined partitions.
++
++ If you need code which can detect and parse these tables, and
++ register MTD 'partitions' corresponding to each image detected,
++ enable this option.
++
++ You will still need the parsing functions to be called by the driver
++ for your particular device. It won't happen automatically.

++2005-05-22 root <mk@mary>
++
++ * Added overlay script that allows to easily mount mini_fo ontop

++
++2005-05-10 <mk@mary>
++
++ * inode.c: xattr functions return -EOPNOSUPP instead of
++ -ENOSUPP, what confuses "ls -l"
++
++ * Changed license from LGPL to GPL.
++
++2005-05-08 root <mk@mary>
++
++ * Makefile: clean it up and added make install and make
++ uninstall.
++
++2005-05-06 <mk@mary>
++
++ * merged devel branch back to main. [v0-6-0-pre3]
++
++ * removed unused files print.c and fist_ioctl. [devel-0-0-18]
++
++ * ioctl: removed fist_ioctl stuff, that is not needed for
++ now.
++
++2005-05-03 <mk@mary>
++
++ * file.c: simplified mini_fo_open and mini_fo_setattr using
++ new state changing functions. [devel-0-0-17]
++
++ * inode.c: Fixed getattr state bug (see below) in 2.4 function
++ mini_fo_inode revalidate.
++
++ * inode.c: found an other bug in mini_fo_getattr. States are not
++ reliable in this function, as a file can be opened, unlinked and
++ the getattr function called. This results in a deleted dentry
++ with an inode. Fix is to ignore states and simply use the inode
++ available.
++
++2005-04-29 <mk@mary>
++
++ * file.c: Bugfix and cleanup in fasync and fsync. [devel-0-0-16]
++
++ * file.c: do not use mini_fo_lock so the generic version is
++ used (I guess).
++
++ * inode.c: getattr, never call getattr on lower files, as this
++ will cause the inum to change.
++
++ * inode.c: rename_reg_file renamed to rename_nondir, as it
++ doesn't matter as long it't not a dir. Removed all
++ rename_dev_file etc.
++
++ * tagged as devel-0-0-15
++
++ * inode.c: added support for chosing support for extended
++ attrs at compile time by XATTR define in mini_fo.h .
++
++ * inode.c: fixed mini_fo_getattr to use mini_fo inode and not
++ lower again, what avoids inode number changes that confused
++ rm again. This is the proper solution.
++
++2005-04-24 <mk@mary>
++
++ * all files: updated Copyright notive to 2005. [devel-0-0-14]
++
++ * inode.c: fixed mini_fo_getattr to not change the inode
++ number, even if lower files change.
++
++ * super.c: fixed a bug that caused deleted base file to show
++ up suddenly after some time, or after creating a special
++ file. The problem was that after some time or after special
++ file creating sync_sb_inodes is called by the vfs, that
++ called our mini_fo_put_inode. There was (wrongly) called
++ __meta_put_lists, that nuked the lists, although the inode
++ was going to continue its life. Moving __meta_put_lists to
++ mini_fo_clear_inode, where an inode is really destroyed,
++ solved the problem.
++
++
++2005-04-23 <mk@mary>
++
++ * state.c, aux.c: more cleaning up and
++ simplifications. [devel-0-0-13]
++
++ * inode.c: implemented mini_fo_getattr, that was required for
++ 2.6 because inode_revalidate has been remove there, and the
++ old "du" bug returned.
++
++
++2005-04-20 <mk@mary>
++
++ * aux.c: get_neg_sto_dentry(): allow to be called for dentries
++ in state UNMODIFIED, NON_EXISTANT _and_ DELETED.
++
++2005-04-19 <mk@mary>
++
++ * Fixed a bug under 2.6 that caused files deleted via mini_fo
++ not to be deleted properly and therefore the fs filled up
++ untill no memory was left. [devel-0-0-12]
++
++ * Added basic hard link support. This means that creating
++ hardlinks will work, but existing ones will be treated as
++ individual files. [devel-0-0-11]
++
++2005-04-17 <mk@mary>
++
++ * Bugfixes
++
++2005-04-13 root <mk@mary>
++
++ * Added file state.c for the state transition
++ functions. Doesn't work very well yet, though...
++
++2005-04-12 <mk@mary>
++
++ * Porting to 2.6 started, which is easier than expected, also
++ due to Olivier previous work.
++
++2005-04-08 <mk@mary>
++
++ * Fixed the bug that caused du to return invalid sizes of
++ directory trees. The problem was that
++ mini_fo_inode_revalidate didn't always copy the attributes
++ from the base inode properly.
++
++2005-04-01 Markus Klotzbuecher <mk@chasey>
++
++ * Merged devel branch back to main trunk and updated the
++ RELEASE notes. This will be 0-6-0-pre1.
++
++2005-03-31 Markus Klotzbuecher <mk@chasey>
++
++ * Fixed some bugs in rename_reg_file, that only showed up in
++ the kernel compile test. Kernel compiles cleanly ontop of
++ mini_fo, now also make mrproper etc. work. Seems pretty stable.
++
++2005-03-28 Markus Klotzbuecher <mk@chasey>
++
++ * Many, many directory renaming bugfixes and a lot of other
++ cleanup. Dir renaming seems to work relatively stable.
++
++2005-03-22 Markus Klotzbuecher <mk@chasey>
++
++ * Finished implementing lightweight directory renaming. Some
++ basic testing indicates it works fine.
++ Next is to implement testcases for the testsuite and confirm
++ everything is really working ok.
++
++2005-03-18 Markus Klotzbuecher <mk@chasey>
++
++ * Finished implementing meta.c stuff required for directory
++ renaming.
++
++2005-03-17 Markus Klotzbuecher <mk@chasey>
++
++ * Fixed all compile warnings + an extremly old bug that
++ somehow crept in while reworking the wol stuff to the META
++ system. Turning on -Werror again... :-)
++
++ * Fixed some bugs in the new rename_reg_file function.
++
++ * Rewrote mini_fo rename and split it into several
++ subfunctions, that handle the different types
++ seperately. Rewrote the regular file function aswell, as it
++ was implemented somewhat inefficient.
++
++2005-03-16 Markus Klotzbuecher <mk@chasey>
++
++ * Implemented new META subsystem, removed old WOL stuff in favor
++ if it.
++
++ * After some basic testing everything seems ok...
++
++2005-03-11 Markus Klotzbuecher <mk@chasey>
++
++ * Renaming a non regular file caused trouble because I always
++ tried to copy the contents. Now I only do this for regular
++ files. mini_fo_rename still isn't implemented properly, renaming
++ of device files, symlinks etc. results in a empty regular file
++ instead of the proper type.
++
++ * Directory renaming suddenly works! What a surprise! I guess
++ this is because renaming is implemented as making a copy and
++ removing the original. Still this might not work
++ everywhere...
++
++2005-03-09 Markus Klotzbuecher <mk@chasey>
++
++ * Bugfix, when a mini_fo directory that exists in storage
++ (state: MODIFIED, CREATED and DEL_REWRITTEN) is deleted, a
++ possibly existing WOL file contained in it needs to be
++ deleted too.
++
++ * Starting cleanup: defined state names in order to get rid of
++ the state numbers.
++
++2005-03-08 Markus Klotzbuecher <mk@chasey>
++
++ * Makefile fix, fist_ioctl was built against wrong sources if ARCH=um
++
++ * Fixed a bug in dentry.c, mini_fo_d_hash. In state 4 =
++ DEL_REWRITTEN the hash was calculated from the base dentry,
++ which was wrong and and caused assertions in
++ __mini_fo_hidden_dentry to fail.
++
++2005-02-21 <mk@mary>
++
++ * Implemented directory deleting (inode.c)
++
++ * main.c: made mini_fo_parse_options a little more robust.
++
++2004-12-22 <mk@mary>
++
++ * Makefile cleanup and uml stuff, removed unneccessary files
++
++ * Created a new and hopefully more informative README
++
++ * CHANGELOG: created a new CHANGELOG and added old entries reversely
++
++
++2004-10-24 Gleb Natapov <gleb@nbase.co.il>
++
++ * Fix: owner and group where not correctly copied from base to
++ storage.
++
++
++2004-10-05 Gleb Natapov <gleb@nbase.co.il>
++
++ * Implementation of fsync, fasync and lock mini_fo functions.
++
++
++2004-09-29 Bob Lee <bob@pantasys.com>
++
++ * Fix of a serious pointer bug
++
++
++2004-09-28 Gleb Natapov <gleb@nbase.co.il>
++
++ * Implementation of mini_fo_mknod and mini_fo_rename, support
++ for device files.

++README for the mini_fo overlay file system
++=========================================
++
++
++WHAT IS MINI_FO?
++----------------
++
++mini_fo is a virtual kernel file system that can make read-only
++file systems writable. This is done by redirecting modifying operations
++to a writeable location called "storage directory", and leaving the
++original data in the "base directory" untouched. When reading, the
++file system merges the modifed and original data so that only the
++newest versions will appear. This occurs transparently to the user,
++who can access the data like on any other read-write file system.
++
++Base and storage directories may be located on the same or on
++different partitions and may be of different file system types. While
++the storage directory obviously needs to be writable, the base may or
++may not be writable, what doesn't matter as it will no be modified
++anyway.
++
++
++WHAT IS GOOD FOR?
++-----------------
++
++The primary purpose of the mini_fo file system is to allow easy
++software updates to embedded systems, that often store their root
++file system in a read-only flash file system, but there are many
++more as for example sandboxing, or for allowing live-cds to
++permanently store information.
++
++
++BUILDING
++--------
++This should be simple. Adjust the Makefile to point to the correct
++kernel headers you want to build the module for. Then:
++
++ # make
++
++should build "mini_fo.o" for a 2.4 kernel or "mini_fo.ko" for a 2.6
++kernel.
++
++If you are building the module for you current kernel, you can install
++the module (as root):
++
++ # make install
++
++or uninstall with
++
++ # make uninstall
++
++
++USING THE FILE SYSTEM
++--------------------
++
++the general mount syntax is:
++
++ mount -t mini_fo -o base=<base directory>,sto=<storage directory>\
++ <base directory> <mount point>
++
++Example:
++
++You have mounted a cdrom to /mnt/cdrom and want to modifiy some files
++on it:
++
++load the module (as root)
++
++ # insmod mini_fo.o for a 2.4 kernel or
++
++ # insmod mini_fo.ko for a 2.6 kernel
++
++
++create a storage dir in tmp and a mountpoint for mini_fo:
++
++ # mkdir /tmp/sto
++ # mkdir /mnt/mini_fo
++
++and mount the mini_fo file system:
++
++ # mount -t mini_fo -o base=/mnt/cdrom,sto=/tmp/sto /mnt/cdrom /mnt/mini_fo
++
++
++Now the data stored on the cd can be accessed via the mini_fo
++mountpoint just like any read-write file system, files can be modified
++and deleted, new ones can be created and so on. When done unmount the
++file system:
++
++ # unmount /mnt/mini_fo
++
++Note that if the file system is mounted again using the same storage
++file system, of course it will appear in the modified state again. If
++you remount it using an new empty storage directory, it will be
++unmodified. Therefore by executing:
++
++ # cd /tmp/sto
++ # rm -rf *
++
++you can nuke all the changes you made to the original file system. But
++ remember NEVER do this while the mini_fo file system is mounted!
++
++
++Alternatively you can use the mini_fo-overlay bash script, that
++simplifies managing mini_fo mounts. See TOOLS Section.
++
++
++TOOLS
++-----
++
++mini_fo-merge (experimental):
++
++This is a bash script that will merge changes contained in the storage
++directory back to the base directory. This allows mini_fo to function
++as a cache file system by overlaying a slow (network, ...) file system
++and using a fast (ramdisk, ...) as storage. When done, changes can be
++merged back to the (slow) base with mini_fo-merge. See "mini_fo-merge
++-h" for details.
++
++It can be usefull for merging changes back after a successfull test
++(patches, software updates...)
++
++
++mini_fo-overlay:
++
++This bash script simplifies managing one or more mini_fo mounts. For
++overlaying a directory called "basedir1", you can just call:
++
++ # mini_fo-overlay basedir1
++
++This will mount mini_fo with "basedir1" as base, "/tmp/sto-basedir1/"
++as storage to "/mnt/mini_fo-basedir1/". It has more options though,
++type "mini_fo-overlay -h" for details.
++
++
++DOCUMENTATION, REPORTING BUGS, GETTING HELP
++-------------------------------------------
++
++Please visit the mini_fo project page at:
++
++http://www.denx.de/twiki/bin/view/Know/MiniFOHome
++
++
++WARNINGS
++--------
++
++Never modify the base or the storage directorys while the mini_fo
++file system is mounted, or you might crash you system. Simply accessing
++and reading should not cause any trouble.
++
++Exporting a mini_fo mount point via NFS has not been tested, and may
++or may not work.
++
++Check the RELEASE_NOTES for details on bugs and features.

++Release: mini_fo-0.6.1 (v0-6-1)
++Date: 21.09.2005
++
++
++Changes:
++--------
++v0-6-1:
++
++- bugfixes (see ChangeLog)
++
++- two helper scripts "mini_fo_merge" and "mini_fo_overlay" (see
++ README for details).
++
++v0-6-0:
++
++- Support for 2.4 and 2.6 (see Makefile)
++
++- Partial hard link support (creating works as expected, but already
++ existing links in the base file system will be treated as if they
++ were individual files).
++
++- Various bugfixes and cleanups.
++
++
++v0-6-0-pre1:
++
++- This is mini_fo-0-6-0-pre1! This release is a complete rewrite of
++ many vital mini_fo parts such as the old whiteout list code which
++ has been replaced by the new META subsystem.
++
++- Light weight directory renaming implemented. This means if a
++ directory is renamed via the mini_fo filesystem this will no longer
++ result in a complete copy in storage, instead only one empty
++ directory will be created. All base filed contained in the original
++ directory stay there until modified.
++
++- Special files (creating, renaming, deleting etc.) now working.
++
++- Many bugfixes and cleanup, mini_fo is now a lot more stable.
++
++
++v0-5-10:
++
++- Final release of the 0-5-* versions. Next will be a complete rewrite
++ of many features. This release contains several bugfixes related to
++ directory renaming.
++
++
++v0-5-10-pre6:
++
++- Lots of cleanup and several bugfixes related to directory deleting
++
++- Directory renaming suddenly works, what is most likely due to the
++ fact tha that "mv" is smart: if the classic rename doesn't work it
++ will assume that source and target file are on different fs and will
++ copy the directory and try to remove the source directory. Until
++ directory removing wasn't implemented, it would fail to do this and
++ rollback.
++ So, directory renaming works for now, but it doesn't yet do what you
++ would expect from a overlay fs, so use with care.
++
++
++v0-5-10-pre5:
++
++- implemented directory deleting
++- made parsing of mount options more stable
++- New format of mount options! (See README)
++- I can't reproduce the unknown panic with 2.4.25 anymore, so I'll
++ happily assume it never existed!
++
++
++Implemented features:
++---------------------
++
++- creating hard links (see BUGS on already existing hard links)
++- lightweight directory renaming
++- renaming device files, pipes, sockets, etc.
++- creating, renaming, deleting of special files
++- deleting directorys
++- general directory reading (simple "ls" )
++- creating files in existing directorys
++- creating directorys
++- renaming files.
++- reading and writing files (involves opening)
++- appending to files (creates copy in storage)
++- deleting files
++- llseek works too, what allows editors to work
++- persistency (a deleted file stay deleted over remounts)
++- use of symbolic links
++- creating of device files
++
++
++Not (yet) implemented features:
++-------------------------------
++
++- full hard link support.
++
++
++
++BUGS:
++-----
++
++Hard links in the base file system will be treated as individual
++files, not as links to one inode.
++
++The main problem with hard links isn't allowing to create them, but
++their pure existence. If you modify a base hard link, the changes made
++will only show up on this link, the other link will remain in the
++original state. I hope to fix this someday. Please note that this does
++not effect the special hard links '.' and '..', that are handled
++seperately by the lower fs.

++GPIOMMC - Driver for an MMC/SD card on a bitbanging GPIO SPI bus
++================================================================
++
++The gpiommc module hooks up the mmc_spi and spi_gpio modules for running an
++MMC or SD card on GPIO pins.
++
++Two interfaces for registering a new MMC/SD card device are provided:
++A static platform-device based mechanism and a dynamic configfs based interface.
++
++
++Registering devices via platform-device
++=======================================
++
++The platform-device interface is used for registering MMC/SD devices that are
++part of the hardware platform. This is most useful only for embedded machines
++with MMC/SD devices statically connected to the platform GPIO bus.
++
++The data structures are declared in <linux/mmc/gpiommc.h>.
++
++To register a new device, define an instance of struct gpiommc_platform_data.
++This structure holds any information about how the device is hooked up to the
++GPIO pins and what hardware modes the device supports. See the docbook-style
++documentation in the header file for more information on the struct fields.
++
++Then allocate a new instance of a platform device by doing:
++
++ pdev = platform_device_alloc(GPIOMMC_PLATDEV_NAME, gpiommc_next_id());
++
++This will allocate the platform device data structures and hook it up to the
++gpiommc driver.
++Then add the gpiommc_platform_data to the platform device.
++
++ err = platform_device_add_data(pdev, pdata, sizeof(struct gpiommc_platform_data));
++
++You may free the local instance of struct gpiommc_platform_data now. (So the
++struct may be allocated on the stack, too).
++Now simply register the platform device.
++
++ err = platform_device_add(pdev);
++
++Done. The gpiommc probe routine will be invoked now and you should see a kernel
++log message for the added device.
++
++
++Registering devices via configfs
++================================
++
++MMC/SD cards connected via GPIO often are a pretty dynamic thing, as for example
++selfmade hacks for soldering an MMC/SD card to standard GPIO pins on embedded
++hardware are a common situation.
++So we provide a dynamic interface to conveniently handle adding and removing
++devices from userspace, without the need to recompile the kernel.
++
++The "gpiommc" subdirectory at the configfs mountpoint is used for handling
++the dynamic configuration.
++
++To create a new device, it must first be allocated with mkdir.
++The following command will allocate a device named "my_mmc":
++ mkdir /config/gpiommc/my_mmc
++
++There are several configuration files available in the new
++/config/gpiommc/my_mmc/ directory:
++
++gpio_data_in = The SPI data-IN GPIO pin number.
++gpio_data_out = The SPI data-OUT GPIO pin number.
++gpio_clock = The SPI Clock GPIO pin number.
++gpio_chipselect = The SPI Chipselect GPIO pin number.
++gpio_chipselect_activelow = Boolean. If 0, Chipselect is active-HIGH.
++ If 1, Chipselect is active-LOW.
++spi_mode = The SPI data mode. Can be 0-3.
++spi_delay = Enable all delays in the lowlevel bitbanging.
++max_bus_speed = The maximum SPI bus speed. In Hertz.
++
++register = Not a configuration parameter.
++ Used to register the configured card
++ with the kernel.
++
++The device must first get configured and then registered by writing "1" to
++the "register" file.
++The configuration parameters "gpio_data_in", "gpio_data_out", "gpio_clock"
++and "gpio_chipselect" are essential and _must_ be configured before writing
++"1" to the "register" file. The registration will fail, otherwise.
++
++The default values for the other parameters are:
++gpio_chipselect_activelow = 1 (CS active-LOW)
++spi_mode = 0 (SPI_MODE_0)
++spi_delay = 1 (enabled)
++max_bus_speed = 5000000 (5 Mhz)
++
++Configuration values can not be changed after registration. To unregister
++the device, write a "0" to the "register" file. The configuration can be
++changed again after unregistering.
++
++To completely remove the device, simply rmdir the directory
++(/config/gpiommc/my_mmc in this example).
++There's no need to first unregister the device before removing it. That will
++be done automatically.
