* This patch adds support for a new SPI programmer, based on the FT2232H/4232H ↵Paul Fox2009-06-161-1/+19
| | | | | | | | | | | | | | | | | | | | | | | | 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. Carl-Daniel writes: There is one additional FIXME comment in the code, but AFAICS that problem is not solvable with current libftdi. Corresponding to flashrom svn r598.

* Support reads of arbitrary rangeCarl-Daniel Hailfinger2009-06-161-5/+6
| | | | | | | | | | | | That means you can tell flashrom to read exactly bytes 12345-56789 (start 12345, length 44445) and it will not fetch a single byte more. Uwe tested this on one LPC, one SPI, and one parallel flash board. Corresponding to flashrom svn r596.

* Flashrom only checks for very few chips if the erase workedCarl-Daniel Hailfinger2009-06-151-0/+88
| | | | | | | | | | | | | | | | | | | 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. Uwe successfully tested LPC on an CK804 box and SPI on some SB600 box. Corresponding to flashrom svn r595.

* Every SPI host controller implemented its own way to read flash chipsCarl-Daniel Hailfinger2009-06-131-0/+5
| | | | | | | | | | | | | | | | | | | | | | 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.

* Flashrom does not honor argument ordering for operationsCarl-Daniel Hailfinger2009-06-121-2/+24
| | | | | | | | | | | | | | Not only does this violate the principle of least surprise, it also caused one bug where -Ewv was specified and the flash ended up being empty.

* Sometimes we want to read/write more than 4 bytes of chip content at onceCarl-Daniel Hailfinger2009-06-051-17/+30
| | | | | | | | | | | | | | | | | | | | 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.

* Only probe for chips with compatible bus protocolsCarl-Daniel Hailfinger2009-06-011-0/+50
| | | | | | | | | | | | | | | | | | It doesn't make sense to probe for SPI chips on a LPC host, nor does it make sense to probe for LPC chips on a Parallel host. This change is backwards compatible, but adding host protocol info to chipset init functions will speed up probing. Once all chipset init functions are updated and the Winbond W29EE011 and AMIC A49LF040A chip definitions are updated, the W29EE011 workaround can be deleted as the W29/A49 conflict magically disappears.

| | | | | | | | | | | | | | | | | | | 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. Corresponding to flashrom svn r519.
