* Store block sizes and corresponding erase functions in struct flashchipCarl-Daniel Hailfinger2009-09-051-0/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I decided to fill in the info for a few chips to illustrate how this works both for uniform and non-uniform sector sizes. struct eraseblock{ int size; /* Eraseblock size */ int count; /* Number of contiguous blocks with that size */ }; struct eraseblock doesn't correspond with a single erase block, but with a group of contiguous erase blocks having the same size. Given a (top boot block) flash chip with the following weird, but real-life structure: top 16384 8192 8192 32768 65536 65536 65536 65536 65536 65536 65536 bottom we get the following encoding: {65536,7},{32768,1},{8192,2},{16384,1} Although the number of blocks is bigger than 4, the number of block groups is only 4. If you ever add some flash chips with more than 4 contiguous block groups, the definition will not fit into the 4-member array anymore and gcc will recognize that and error out. No undetected overflow possible. In that case, you simply increase array size a bit. For modern flash chips with uniform erase block size, you only need one array member anyway. Of course data types will need to be changed if you ever get flash chips with more than 2^30 erase blocks, but even with the lowest known erase granularity of 256 bytes, these flash chips will have to have a size of a quarter Terabyte. I'm pretty confident we won't see such big EEPROMs in the near future (or at least not attached in a way that makes flashrom usable). For SPI chips, we even have a guaranteed safety factor of 4096 over the maximum SPI chip size (which is 2^24). And if such a big flash chip has uniform erase block size, you could even split it among the 4 array members. If you change int count to unsigned int count, the storable size doubles. So with a split and a slight change of data type, the maximum ROM chip size is 2 Terabytes. Since many chips have multiple block erase functions where the eraseblock layout depends on the block erase function, this patch couples the block erase functions with their eraseblock layouts. struct block_eraser { struct eraseblock{ unsigned int size; /* Eraseblock size */ unsigned int count; /* Number of contiguous blocks with that size */ } eraseblocks[NUM_ERASEREGIONS]; int (*block_erase) (struct flashchip *flash, unsigned int blockaddr, unsigned int blocklen); } block_erasers[NUM_ERASEFUNCTIONS]; Corresponding to flashrom svn r719.

| | | | | | | | | | | | | Flashrom has the ability to use layout files with romentries, but this feature was not adapted to the programmer infrastructure and had undefined behaviour for flasher!=internal.

* This is a workaround for a bug in SB600 and SB700Carl-Daniel Hailfinger2009-07-231-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | If we only send an opcode and no additional data/address, the SPI controller will read one byte too few from the chip. Basically, the last byte of the chip response is discarded and will not end up in the FIFO. It is unclear if the CS# line is set high too early as well. That hardware bug is undocumented as of now, but I'm working with AMD to add a detailed description of it to the errata. Add loads of additional debugging to SB600/SB700 init. Add explanatory comments for unintuitive code flow. Thanks go to Uwe for testing quite a few iterations of the patch. Kill the SB600 flash chip status register special case, which was a somewhat misguided workaround for that hardware erratum. Note for future added features in the SB600 SPI driver: It may be possible to read up to 15 bytes of command response with overlapping reads due to the ring buffer design of the FIFO if the command can be repeated without ill effects. Same for skipping up to 7 bytes between command and response. Corresponding to flashrom svn r661.

* Add SPI multicommand infrastructureCarl-Daniel Hailfinger2009-07-101-7/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Add bus type support to the dummy external programmerCarl-Daniel Hailfinger2009-06-011-0/+2
| | | | | | | | | | | | | | | The syntax is explained in the man page. Example: flashrom -p dummy=lpc,fwh Tested, works perfectly. ;-) As a nice benefit, it allows easy testing of the "probe only compatible flashes" patch. Corresponding to flashrom svn r559.

* Add IT87xx SPI as external flasher optionCarl-Daniel Hailfinger2009-05-311-0/+2
| | | | | | | | | | This is a fast way to test if a IT87xx board_enable() would work. Corresponding to flashrom svn r557. Signed-off-by: Carl-Daniel Hailfinger <c-d.hailfinger.devel.2006@gmx.net> Tested-by: Harald Gutmann <harald.gutmann@gmx.net> Acked-by: Harald Gutmann <harald.gutmann@gmx.net>
* Add bus type annotation to struct flashchipsCarl-Daniel Hailfinger2009-05-311-14/+25
| | | | | | | | | | | | | | | | | | | 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. Corresponding to flashrom svn r556.

* Add support for probe and read of Intel 28F001BX-T and BX-BUrja Rannikko2009-05-291-0/+2
| | | | | | | | | | | Erase & write support wont be this easy - the chips need 12V Vpp (needs a hardware hack or a supporting mb) and they have a very weird layout and are old.

* Random flashrom updatesUwe Hermann2009-05-281-19/+17
| | | | | | | | | | | | | | | | | | | | - Add explicit installation instructions in the README. - Code cleanups, coding style fixes, drop dead code. - Drop duplicate board listings from -L output (some boards were explicitly recorded in boards_ok[] _and_ implicitly via the board-enables table. - Add MS-xxxx numbers to MSI boards where we can find that info. - Fix typo, "K8T Neo2" should have been "K8T Neo2-F" actually, at least according to the comment of w83627thf_gpio4_4_raise_2e() which says "Suited for: MSI K8T Neo2-F".

* Refactor SuperIO accessesCarl-Daniel Hailfinger2009-05-251-3/+5
| | | | | | | | | | | | | | | We had duplicated code under different names and even open-coded some functions in some places. wbsio_read/regval -> sio_read wbsio_write/regwrite -> sio_write wbsio_mask -> sio_mask board_biostar_p4m80_m4 now uses existing IT87 functions.
