[patch] add intel_piix4_gpo_set()
by Luc Verhaegen Dec. 14, 2009

Dec. 14, 2009

This is code from a an old board enable that i sent in 3 weeks ago. This board enable was not necessary (as flashing worked just fine without it too). But this function was also used to clean up the board enable for the epox ep bx3. I have tracked down the person for whom i wrote this board enable 2 years ago: irc user nyu, aka Robert Millan. Robert, can you verify that this code is not a regression for you? Uwe, in the original mail thread (http://www.coreboot.org/pipermail/coreboot/2009-June/049789.html) you had several suggestions. I have taken over unsigned int and the bitshift, but i do mot like to put "PIIX4{,E,M}" everywhere. "PIIX4{,E,M}" all over clutters up the place, and i fear that printing this to the user will generate more confusion than it will ever remove. Instead i have adjusted the initial function comment to mention this so that developers can rest assured in future that this will also be valid for their future board enables. Luc Verhaegen.

[Patch] Shuttle AK31
by Luc Verhaegen Dec. 14, 2009

Dec. 14, 2009

Resending this patch to the newly formed flashrom ml. Ron already kindly acked this patch. Mateusz, the owner of this board gave me a brief comment on irc stating that it didn't work. Which is also the last i heard from him. Mateusz, get back to us and get us at least the flashrom output. Luc Verhaegen.

[PATCH] Totally generic SPI chip match
by Carl-Daniel Hailfinger Nov. 20, 2009

Nov. 20, 2009

If a chip is not on the RDID generic vendor list nor on the REMS specific ID list, flashrom will claim that no chip is there. Handle these cases gracefully. flashrom will ignore generic matches if a specific chip was found, so this will have no impact on supported chips, but help a lot for a first quick analysis by the user or developer. The only drawback is that unknown chips may be recognized multiple times until they are added to flashchips.[ch].

[PATCH] Add -p gfxnvidia for flashing NVIDIA graphics cards
by Uwe Hermann Sept. 30, 2009

Sept. 30, 2009

See patch. Please do NOT try write/erase on any important cards yet, it doesn't seem to fully work properly yet and you could "brick" your card. I tested a "RIVA TNT2 Model 64/Model 64 Pro", which successfully identified and read a Winbond W29C011 chip, but erase and write behaved incorrect and I finally bricked the card. Will look into recovery soon (likely will work via software I assume, no hardware hacking strictly required I think/hope, we'll see). As for the list of supported cards: I have no idea which of those may work (i.e. have the same flash programming interface), maybe none, maybe all of them (and lots more NVIDIA cards), we'll see as soon as others test more cards.

[PATCH] ICH6-ICH10 flash decode debugging
by Carl-Daniel Hailfinger July 30, 2009

July 30, 2009

Add ICH6,ICH7,ICH8,ICH9,ICH10 FWH IDSEL settings and flash decode settings to the debug output. This can help debug cases where the BIOS does not set up a correct flash decode for the given flash size. The Intel docs state that the decode applies to FWH and SPI flash.
