* Always require the --programmer parameter if any flash chip access is requestedCarl-Daniel Hailfinger2012-07-223-107/+67

* Automatically release I/O permissions on shutdownCarl-Daniel Hailfinger2012-07-2115-57/+56
| | | | | | | | | | | | | | | | | | | | | Get_io_perms() is renamed to rget_io_perms() and automatically registers a function to release I/O permissions on shutdown. Actually release I/O permissions on Solaris and iopl()-supporting operating systems like Linux. This patch fixes quite a few programmers which forgot to release I/O permissions on shutdown, and it simplifies the shutdown and error handling code for all others. Do not call exit(1) if I/O permissions are denied and return an error instead. This part of the patch was written by Niklas Söderlund. Corresponding to flashrom svn r1551.

* Add native SPI AAI write support to the Dediprog SF100 driverNico Huber2012-06-191-20/+47
| | | | | | | | | | | | | To tell the programmer how to handle the data on the spi bus, a flag in the fourth byte sent with the usb command is used. The second word was mistaken for the size of the chunks sent over usb earlier. The third byte (first of the second word) is now set to zero. This also adds some checks for the size of data chunks sent over usb. Corresponding to flashrom svn r1546.

* Add voltage change delays to dediprog driverNico Huber2012-06-161-0/+8
| | | | | | | | | | | Some investigations have shown that the original dediprog driver waits about 200ms after setting voltage up and before setting voltage down. This patch adds those delays.

* Let the programmer driver decide how to do AAI transfersNico Huber2012-06-1515-3/+24
| | | | | | | | | | | | | | | | Currently spi_aai_write() is implemented without an abstraction mechanism for the programmer driver. This adds another function pointer 'write_aai' to struct spi_programmer, which is set to default_spi_write_aai (renamed spi_aai_write) for all programmers for now. A patch which utilises this abstraction in the dediprog driver will follow. Corresponding to flashrom svn r1543.

* spi25.c: Refactor spi_write_status_register helpersStefan Tauner2012-05-021-58/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | In r1115 "Write protection handling for Atmel AT25*" the old spi_write_status_register function was duplicated to send WREN and EWSR commands respectively controlled by a new common wrapper function spi_write_status_register without a reason. Both functions' resulting code is equal apart from the opcode used. The code itself does also differ in the macros used, but their value (apart from the opcode) is equal. This patch adds a new parameter for the opcode to the helper function which allows removal of the other one. This relies on the fact that EWSR and WREN have the same INSIZE and OUTSIZE though. If that is really seen as an issue, the sizes could be made parameters too. This patch also changes the wrapper so that it no longer sets the feature bits of the struct flash(ctx) argument. This may result in changed output, because it no longer implicitly disables the debug message in following executions. Since almost all chips had their feature bits fixed in the previous commit, this is a minor problem. Also, spi_write_status_enable has been dead code since r658 or so. Remove it.

* Tag all EWSR chips correctlySteven Zakulec2012-05-022-2/+87
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All SPI chips without a WRSR feature bit set were evaluated except the Sanyo LF25FW203A for which no datasheet is available. The following list includes all SPI-capable chips that still have no WRSR feature bit set: - AT26DF041 - AT45CS1282 - AT45DB011D - AT45DB021D - AT45DB041D - AT45DB081D - AT45DB161D - AT45DB321C - AT45DB321D - AT45DB642D All of them have no write function set and can be therefore ignored for now. Apart from those the generic chips are also not tagged. The opaque flash interface should not be affected. The SFDP dummy chip is changed to explicitly set EWSR if it can't deduce it dynamically. The vendor detecting generic chips can't write anyway. Corresponding to flashrom svn r1527.

* Fix parallel-style programmer access from ITE IT87/Winbond W83627 SPICarl-Daniel Hailfinger2012-03-015-4/+12
| | | | | | | | | | | | | | | | | | | | | | | | The ITE IT87 SPI driver uses a trick to speed up reading and writing: If a flash chip is 512 kByte or less, the flash chip can be completely mapped in memory and both read and write accesses are faster that way. The current IT87 SPI code did use the parallel programmer interface for memory mapped reads and writes, but that's the wrong abstraction. It has been fixed to use mmio_read*/mmio_write* for that purpose. The Winbond W83627 SPI driver uses the same trick in its read path for all supported chip sizes. Fix it the same way. Switch internal_chip_readn to use mmio_readn as proper abstraction. Kudos to Michael Karcher for spotting the bugs.

* SFDP: Fetch parameter table in a more portable wayCarl-Daniel Hailfinger2012-02-241-7/+16
| | | | | | | | | | | | | SFDP parameter table reads expect a dummy byte between written data (opcode+address) and read data on the SPI bus. Read that dummy byte instead of writing it to be compatible with all programmer drivers. Reduce SFDP parameter table read chunk size from 8 to 2 to handle programmers with small readcount limits.

* Fix SFDP probingStefan Tauner2012-02-221-26/+39
| | | | | | | | | | | | | | | | | | | | | | Sfdp_add_uniform_eraser checks for existing erasers. Due to a bug it looked for eraser slots that have no erase functions set instead of those that have one set. Postpone adding an erase function for the special 4k block erase opcode until we know the flash chip size and add an additional check to sfdp_add_uniform_eraser. Fix the output of the parameter table contents. This patch fixes the index used to retrieve the eraser types, which was off one double word. Refine some messages and add a few further debugging prints. Corresponding to flashrom svn r1505.

I would only use this patch to read and verify the existing contents, just to be safe. The PCI IDs of the onboard devices do contain no subsystem IDs at all.

* Add support for SFDP (JESD216)Stefan Tauner2012-02-179-12/+467
| | | | | | | | | | | | | | | | | | | | | | | | | | | Similar to modules using the opaque programmer framework (e.g. ICH Hardware Sequencing) this uses a template struct flashchip element in flashchips.c with a special probe function that fills the obtained values into that struct. This allows yet unknown SPI chips to be supported (read, erase, write) almost as if it was already added to flashchips.c.
