* Increase delay in probe_jedec() to 2ms to reliably detect AT29C020Peter Stuge2008-06-211-1/+1
| | | | | | | | | | Run time is increased a few 100ms but this is needed for reliability. I consider this trivial. Corresponding to flashrom svn r262 and coreboot v2 svn r3373. Signed-off-by: Peter Stuge <peter@stuge.se> Acked-by: Peter Stuge <peter@stuge.se>
* Check the JEDEC vendor ID for correct parityCarl-Daniel Hailfinger2008-05-141-1/+12
| | | | | | | | | | | | Flash chips which can be detected by JEDEC probe routines all have vendor IDs with correct parity. Use a parity check as additional hint whether a vendor ID makes sense. Note: Device IDs have no parity requirements whatsoever. Corresponding to flashrom svn r231 and coreboot v2 svn r3308.

* Add continuation ID support to jedec.cCarl-Daniel Hailfinger2007-12-311-2/+18
| | | | | | | | | | | | | | | | | | | | | | | 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.) Add support for EON EN29F002AT. Corresponding to flashrom svn r171 and coreboot v2 svn r3030.

* Fix ATMEL 29C020 detection with flashromCarl-Daniel Hailfinger2007-11-131-2/+6
| | | | | | | | | | | | The JEDEC probe routine had a delay of 10 us after entering ID mode and this was insufficient for the 29C020. The data sheet claims we have to wait 10 ms, but tests have shown that 20 us suffice. Allow for variations in chip delays with a factor of 2 safety margin.

* Fix write_page_write_jedec() in jedec.cGiampiero Giancipoli2006-11-221-14/+49
| | | | | | | | | | | | | | | | | | | Added a check-reprogram loop in the same function, to come around the high page write failure rate on some boards. This patch includes the changes suggested by Ron to simplify the control flow. It also includes trivial changes by me to make flashrom build on newer systems (libpci needs libz now). I also made a small type case compile fix and proper return code handling in one or two places. Corresponding to flashrom svn r78 and coreboot v2 svn r2505.
