Some SPI opcodes need to be sent in direct succession after each other
without any chip deselect happening in between. A prominent example is
WREN (Write Enable) directly before PP (Page Program). Intel calls the
first opcode in such a row "preopcode".
Right now, we ignore the direct succession requirement completely and it
works pretty well because most onboard SPI masters have a timing or
heuristics which make the problem disappear.
The FT2232 SPI flasher is different. Since it is an external flasher,
timing is very different to what we can expect from onboard flashers and
this leads to failure at slow speeds.
This patch allows any function to submit multiple SPI commands in a
stream to any flasher. Support in the individual flashers isn't
implemented yet, so there is one generic function which passes the each
command in the stream one-by-one to the command functions of the
selected SPI flash driver.

Since block erase functions do not know the block length (it's not
specified in any standard), block erase functions now get an additional
parameter blocklen. This enables flashrom to verify the erase result for
block erase functions at correct boundaries.

Add a --list-supported-wiki / -z option which outputs the currently
supported flash chips (and their status, size, and type), chipsets (plus
status), mainboards (plus status), and external PCI devices usable as
programmer to stdout.
This allows for very easy pasting into the http://coreboot.org/flashrom
page, so we can keep that page up-to-date without much hassle.
The list of boards is mostly new (known good ones which don't need
write-enable code, and known-bad ones) and also lists URLs to the
vendor's mainboard pages.

chip from FTDI
FTDI support is autodetected during compilation.
Paul writes:
There are certainly possible improvements: The code has hard-coded
values for which interface of the ftdi chip to use (interface B was
chosen because libftdi seems to have trouble with A right now), what
clock rate use for the SPI interface (I've been running at 30Mhz, but
the patch sets it to 10Mhz), and possibly others. I think this means
that per-programmer options might be a good idea at some point.

There is one additional FIXME comment in the code, but AFAICS that
problem is not solvable with current libftdi.

And even when it checks if the erase worked, the result of that check is
often ignored.
Convert all erase functions and actually check return codes
almost everywhere.
Check inside all erase_* routines if erase worked, not outside.
erase_sector_jedec and erase_block_jedec have changed prototypes to
enable erase checking.

This was partly due to a design problem in the abstraction layer.
There should be exactly two different functions for reading SPI chips:
- memory mapped reads
- SPI command reads.
Each of them should be contained in a separate function, optionally
taking parameters where needed.
This patch solves the problems mentioned above, shortens the code and
makes the code logic a lot more obvious.
Since open-coding the min() function leads to errors, include it in this
patch as well.

Add chip_{read,write}n to the external flasher infrastructure which
read/write n bytes at once.
Fix a few places where the code used memcpy/memcmp although that is
strictly impossible with external flashers.
Place a FIXME in the layout.c code because usage is not totally clear
and needs to be fixed to support external flashers.
As a nice side benefit, we get a noticeable speedup for builtin flash
reading which is now a memcpy() of the full flash area instead of a
series of single-byte reads.

Right now, the annotation only differentiates between SPI and non-SPI.
Anyone who knows more about a specific flash chip should feel free to
update it.
The existing flashbus variable was abused to denote the SPI controller
type. Use an aptly named variable for that purpose.
Once this patch is merged, the chipset/programmer init functions can set
supported flash chip types and flashrom can automatically select only
matching probe/read/erase/write functions. A side benefit of that will
be the elimination of the Winbond W29EE011 vs. AMIC A49LF040A conflict.

Some MMIO accesses used volatile, others didn't (and risked
non-execution of side effects) and even with volatile, some accesses
looked dubious.
Since the MMIO accessor functions and the onboard flash accessor
functions are functionally identical (but have different signatures),
make the flash accessors wrappers for the MMIO accessors.
For some of the conversions, I used Coccinelle. Semantic patch follows:

Use chipaddr instead of volatile uint8_t * because when we access chips
in external flashers, they are not accessed via pointers at all.
Benefits: This allows us to differentiate between volatile machine
memory accesses and flash chip accesses. It also enforces usage
of chip_{read,write}[bwl] to access flash chips, so nobody will
unintentionally use pointers to access chips anymore. Some unneeded
casts are removed as well. Grepping for chip operations and machine
memory operations doesn't yield any false positives anymore.
Compile tested on 32 bit and 64 bit Linux.

The emulation works by splitting 32 bit accesses into 16 bit accesses

Add support for users to specify a certain NIC via PCI bus:slot.func
notation, in case there are multiple NICs in one system.
Usage: flashrom -p nic3com=bb:ss.f

flasher driver
Does not support reading or writing the fake chip yet.
flashrom --programmer dummy
also enables the dummy SPI controller driver.
Testing the dummy SPI driver revealed a RDID debug printing bug in the
SPI core. Fix that as well.

Among others, I have seen the following problems: - The SPI opcode is
not supported by the controller. ICH-style controllers exhibit this if
SPI config is locked down. - The address in in a prohibited area. This
can happen on ICH for any access (BBAR) and for writes in chipset write
protected areas. - There is no SPI controller.
Introduce separate error codes for unsupported opcode and prohibited
address.
Add the ability to adjust REMS and RES addresses to the minium supported
read address with the help of spi_get_valid_read_addr(). That function
needs to call SPI controller specific functions like reading BBAR on
ICH.

This allows flashrom to identify, read, write, erase and verify flash chips
on (some) 3COM network cards. The patch uses the external programmer
infrastructure, the network card is basically treated as an external
flash programmer.
Usage:
$ ./flashrom -p nic3com
flashrom v0.9.0-r498
Found NIC "3COM 3C905C: EtherLink 10/100 PCI (TX)" (10b7:9200), addr = 0xa400
Calibrating delay loop... OK.
Found chip "Atmel AT49BV512" (64 KB) at physical address 0xffff0000.
No operations were specified.
$ ./flashrom -p nic3com -E
flashrom v0.9.0-r498
Found NIC "3COM 3C905C: EtherLink 10/100 PCI (TX)" (10b7:9200), addr = 0xa400
Calibrating delay loop... OK.
Found chip "Atmel AT49BV512" (64 KB) at physical address 0xffff0000.
Erasing flash chip... SUCCESS.
$ ./flashrom -p nic3com -wv backup.bin
flashrom v0.9.0-r498
Found NIC "3COM 3C905C: EtherLink 10/100 PCI (TX)" (10b7:9200), addr = 0xa400
Calibrating delay loop... OK.
Found chip "Atmel AT49BV512" (64 KB) at physical address 0xffff0000.
Flash image seems to be a legacy BIOS. Disabling checks.
Programming page: 1023 at address: 0x0000ffc0
Verifying flash... VERIFIED.
$ ./flashrom -p nic3com -r backup.bin
flashrom v0.9.0-r498
Found NIC "3COM 3C905C: EtherLink 10/100 PCI (TX)" (10b7:9200), addr = 0xa400
Calibrating delay loop... OK.
Found chip "Atmel AT49BV512" (64 KB) at physical address 0xffff0000.
Reading flash... done.
I have tested this on actual hardware (see PCI IDs above) and all
operations worked fine.
Support for other 3COM cards will follow (I added some more which should
be supportable by this code, but they're untested so far), as well as
support for NICs from other vendors.
The patch also adds support for the Atmel AT49BV512 which is soldered
onto the 3COM NIC I used for testing.

Flash mapping/unmapping was performed without an abstraction layer,
so even the dummy flasher caused memory mappings to be set up. Add
map/unmap functions to the external flasher abstraction.
Fix a possible scribble-over-low-memory corner case which fortunately
never triggered so far.
With this patch, --programmer dummy works fine as non-root.
