* 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.

* Check result of all SPI erase functionsCarl-Daniel Hailfinger2009-06-241-2/+5
| | | | | | | | | | | | | | 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.

* Every SPI host controller implemented its own way to read flash chipsCarl-Daniel Hailfinger2009-06-131-0/+2
| | | | | | | | | | | | | | | | | | | | | | 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.

* Sometimes we want to read/write more than 4 bytes of chip content at onceCarl-Daniel Hailfinger2009-06-051-1/+9

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.

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.

| | | | | | | | | | Factor out portable iopl()-style code into a global function which all programmers can use, add missing close() call. Corresponding to flashrom svn r511. Signed-off-by: Uwe Hermann <uwe@hermann-uwe.de> Acked-by: Uwe Hermann <uwe@hermann-uwe.de>

* Add a dummy SPI controller driver, similar to the dummy LPC/FWH/Parallel ↵Carl-Daniel Hailfinger2009-05-141-1/+4
| | | | | | | | | | | | | | | | | 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. Corresponding to flashrom svn r507.

* There are various reasons why a SPI command can failCarl-Daniel Hailfinger2009-05-131-0/+1
| | | | | | | | | | | | | | | | | | | | | 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. Corresponding to flashrom svn r500.
