| | | | | | | | | | | | | | | Two bits indicate OK and BAD for each operation PROBE READ ERASE WRITE. 8 bits out of 32 are in use now. No bits set means nothing has been tested. For chips with at least one operation that is not tested or not working, the user is asked to email a report to a special email adress so that the table can be updated.

* Separate ST M50FLW support from generic JEDEC codeClaus Gindhart2008-04-281-0/+4
| | | | | | | | | | | | | | | | The generic jedec.c does not work for the ST M50FLW flash devices, because they need an unlock command first. For this reason, ST M50FLW support is moved to a new HW support module, because any change in jedec.c would bear the risk to cause problems with the already supported devices. It's already tested with ST M50FLW080A; the other chips of this family i dont have available, so i couldnt test it. Corresponding to flashrom svn r219 and coreboot v2 svn r3274.

* Add continuation ID support to jedec.cCarl-Daniel Hailfinger2007-12-311-3/+20
| | | | | | | | | | | | | | | | | | | | | | | The continuation ID code does not go further than checking for IDs of the type 0x7fXX, but does this for vendor and product ID. The current published JEDEC spec has a list where the largest vendor ID is 7 bytes long, but all leading bytes are 0x7f. The list will grow in the future, and using a 64bit variable will not be enough anymore. Besides that, it seems that the location of the ID byte after the first continuation ID byte is very vendor specific, so we may have to revisit that code some time in the future. (Suggestion for a new encoding: Use a two-byte data type for the ID, the lower byte contains the only non-0x7f byte, the upper byte contains the number of 0x7f bytes used as prefix, which is the bank number minus 1 the vendor ID appears in.)

* Rename SPI erase functions to include opcodeCarl-Daniel Hailfinger2007-12-171-1/+1
| | | | | | | | | | | | | | | To make it easier to add new SPI chips to flashchips.c, rename functions with multiple possible opcodes from linear numbering at the end (_1, _2) to include the opcode at the end (_60, _c7). That way, you only have to take a short look at the data sheet and choose the right function by appending the opcode listed in the data sheet. No functional changes.

| | | | | | | | | | | | | | | The SPI chip finding and SPI chip accessor code is moved as well. This can be split later if we feel like it. The non-use of svn cp is intentional because the only history we'd have to preserve are a few commits which were early prototypes of chip identification code.

* This patch aims to restructure SPI flash support in a more reasonable wayCarl-Daniel Hailfinger2007-10-021-0/+27
| | | | | | | | | | | | | | | | | | It introduces a generic SPI host driver for the IT8716F Super I/O which will enable easy SPI programming without having to care for the peculiarities of the SPI host. To activate probing for the IT8716F, you have to use the gigabyte:m57sli mainboard override. SPI support will then use the gathered SPI host data to access the SPI flash. This has been tested sucessfully by Ward Vandewege <ward@gnu.org> on the GA-M57SLI v2.0, which has a MX25L4005 SPI flash part. Corresponding to flashrom svn r140 and coreboot v2 svn r2817.
