* Only probe for chips with compatible bus protocolsCarl-Daniel Hailfinger2009-06-016-9/+86
| | | | | | | | | | | | | | | | | | 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.

* Add bus type annotation to struct flashchipsCarl-Daniel Hailfinger2009-05-319-85/+270
| | | | | | | | | | | | | | | | | | | 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.

So the situation for this board will probably not change anytime soon. - MSI MS-6178 (reported by Uwe Hermann <uwe@hermann-uwe.de>) I tested write/erase will not work on this board, so a write-enable is needed. In _addition_, the board immediately powers off if you hot-unplug the PLCC chip, so I guess there's some SMI interference. - GIGABYTE GA-K8N-SLI (reported by Alexander Gordeev <lasaine@lvk.cs.msu.su>) This is currently being discussed on the mailing list (see http://www.coreboot.org/pipermail/coreboot/2009-May/048717.html) and it's very likely that we'll be able to add a board-enable, so this board can be maked as OK soonish.

| | | | | | | | | | | Every chip besides SPI and w39v080fa uses id1/id2 as local variable names to store ID responses from the flash chip. This eases grepping a lot.

* Use REMS instead of RES in the ICH SPI default opcode tableCarl-Daniel Hailfinger2009-05-261-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | RES is Read Electronic Signature (1 Byte, identical for different chips) REMS is Read Electronic Manufacturer Signature (2 Bytes, mostly unique) RDID is Read JEDEC ID (3 bytes, unique) Of the chips which don't support RDID, a sizable portion supports REMS which gives us both a manufacturer ID and a device ID. This is clearly superior to having only a device ID (the RES case) which has multiple documented collisions. The RES/REMS problem is aggravated by inconsistent naming in vendor data sheets. What's in a name? Considering that we have 1-byte IDs, 2-byte IDs and 3+byte IDs with varying names but mostly consistent opcodes, it makes sense to set our own standard about how the opcodes are called. The best way forward would be to have the ICH SPI driver reprogram the opcode menu on the fly if the opcode menu doesn't contain the requested opcode and the opcode menu is not locked. Until that happens, this patch improves detection accuracy by a factor of 256 for some chips. Corresponding to flashrom svn r549.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Some MMIO accesses used volatile, others didn't (and risked non-execution of side effects) and even with volatile, some accesses looked dubious.
