flashrom patch: add support for Abit AB-BM6 board
by Tim ter Laak Sept. 13, 2010

Sept. 13, 2010

Hello all, This patch adds support for the Abit AB-BM6 mainboard to flashrom. The biggest part is a generic function to lower a GPIO line on the PIIX4E southbridge, copied and adapted from its ich_gpio_raise() counterpart (mostly lower instead of raise, followed names from the PIIX4E datasheet). The board specific function then uses this to lower GPO 26. Signed-off-by: Tim ter Laak <timl(a)scintilla.utwente.nl> --- The patch was made from the flashrom subdir, because svn diff from the top-level coreboot dir (as per the directions in the Development Guidelines on the wiki) didn't seem to work for me. Probably because flashrom is fetched externally when checking out coreboot? Anyway, I hope this is okay. If you really prefer a diff from the top-level dir just let me know, and I'll regenerate it with gnu diff. Kind regards, Tim.

[PATCH] Istanbul support
by Arne Georg Gleditsch Sept. 13, 2010

Sept. 13, 2010

Hi, The following patch implements Opteron Fam 10 rev D (aka Istanbul) support for coreboot. I have not updated MAX_CPUS for all fam10 mainboards, but it might make sense to multiply those by 1.5. Signed-off-by: Arne Georg Gleditsch <arne.gleditsch(a)numascale.com> -- Arne.

MS-6147, SeaBIOS, and OpenBSD.
by Mats Erik Andersson Sept. 8, 2010

Sept. 8, 2010

Hello again, two years have passed since I developed the support for MS-6147. Now I return to slowly activate myself again. In a first run I would like to report the following: 1. Coreboot-v4.0, svn rev 5740, works well on MSI MS-6147. 2. In the overview of supported mainboards, there ought to be an entry "Y" for MSI MS-6147, stipulating that the DIL32-ROM is set in a socket. 3. SeaBIOS works on MS-6147, but I had to strip down most functionality in order to fit the combined image into the 64 kB available (120 byte to spare!) since the standard fallback duplication was left intact. No VGA BIOS was included. 4. From this minimal SeaBIOS payload, I did successfully boot into a fully functional OpenBSD 4.4, which I as always use with a serial console. The disk is a 1GB Compact Flash card. Best regards, Mats Erik Andersson, fil. dr <mats.andersson(a)gisladisker.se> Abonnerar på: debian-mentors, debian-devel-games, debian-perl, debian-ipv6, debian-qa

[PATCH] use Kconfig for both options on Lippert boards
by Jens Rottmann Sept. 1, 2010

Sept. 1, 2010

SMC_CONFIG is needed before the device tree is ready and some people would rather not have mainboard settings like sio_gp1x_config in the device tree anyway. So found a nice united home for both in Kconfig, where users can change them without having to mess around in the C code. Signed-off-by: Jens Rottmann <JRottmann(a)LiPPERTEmbedded.de> --- Patrick, BTW, what happened to your patch which made the struct mainboard_config work again? I don't remember it getting committed. I don't use it mainly because SMC_CONFIG is needed early and I perfer not scattering 2 options in different places, but I _do_ think the mainboard logic is a kind of device and might be part (root??) of the tree. So IMHO your patch which reenables this is a very good thing to have!

Real mode ebx corruption
by Myles Watson Aug. 31, 2010

Aug. 31, 2010

Has anyone seen corruption of ebx when using real mode for option ROMs? I'm running the same ROM with SeaBIOS and real mode, and a series of writes (ax = 1ab1 bx = b10d) works fine with SeaBIOS, but several of the bx values are corrupted to b100 with real mode. The only hint I can find is: // Put registers back on the stack. The assembler code // will later pop them. // What happens here is that we force (volatile!) changing // the values of the parameters of this function. We do this // because we know that they stay alive on the stack after // we leave this function. Don't say this is bollocks. *(volatile u32 *)&eax = reg_info.eax; *(volatile u32 *)&ecx = reg_info.ecx; *(volatile u32 *)&edx = reg_info.edx; *(volatile u32 *)&ebx = reg_info.ebx; Since it's real mode, it seems like the only place for corruption is the call & return. Am I missing something? Thanks, Myles
