* Add SPI multicommand infrastructure.hailfinger2009-07-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | once. 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.

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.

| | | | | | | | | | | | | | | | | | | | | 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.
