This patch adds support for the Mitac 6513WU mainboard, a Compaq OEM board using the i810 chipset. Not all hardware has been tested, but my test PC boots Linux (via FILO) without any problems.
The configuration leaves 32 kB for the video BIOS, but the onboard video isn't currently working due to known problems with this chipset.

Great stuff, thanks a lot! This is committed in r4401 with some minor changes.
I dropped all "(C) Uwe Hermann", pretty much all these files are trivial and/or generic, no need to carry over any (C) lines.
- device pci 1.0 on # Chipset Graphics Controller (CGC)
chip drivers/pci/onboarddevice pci 1.0 on endregister "rom_address" = "0xfff80000" #512k imageend- end
I changed this part a bit, this may be nested a bit too much, but maybe I'm wrong, not sure. Either way, the version which is in svn now worked for me on the MS-6178 board, please try a plain svn checkout (r4401) and see if onboard VGA works (better) on your board.
+romimage "normal"
- option CONFIG_USE_FALLBACK_IMAGE = 0
- option COREBOOT_EXTRA_VERSION = ".0Normal"
- payload ../../../../payloads/filo.elf
Changed this to the generic "../payload.elf" we try to use everywhere now (but there may be more changes wrt to this when we move to kconfig for v2).
Uwe.
This patch enables onboard VGA support for the Mitac 6513WU mainboard by defining CONFIG_VIDEO_MB.

The nesting seemed strange to me as well, but the example on the "VGA support" wiki page is written like that.
After defining CONFIG_VIDEO_MB, the VGA device appears in lspci. I haven't tried hooking up a monitor.
I noticed that you moved the subtraction of 32 KB from CONFIG_ROM_SIZE (for the video BIOS) from the mainboard's Options.lb to the target's Config.lb, although the rom_address for this space in still listed in the mainboard's Config.lb. Why was it changed? The division between these files doesn't appear to be well documented, and is inconsistent in existing targets.

That's fine, but it would be good to document the recommended practice since it's not done consistently in the existing code.

Thanks, r4402.

Yeah, true. We're not really consistent with most of the config option stuff. In general, targets/.../Config.lb overrides src/.../Options.lb, but which options are set in which file is inconsistent. IMHO most stuff that a user might want to change (ROM_SIZE, VGA or not, etc) should be in targets/.../Config.lb.
This might all change soonish when we use kconfig for building v2, so it's probably not worth messing with it too much right now.

Yeah, also true. We could mass-patch all targets to use ../payload.elf for consistency, but this will also be obsolete should we use kconfig soon, so not sure if we want to do it right now.
I've set up a page for your board in the wiki: http://www.coreboot.org/Mitac_6513WU See http://www.coreboot.org/MSI_MS-6178 for an example page with status etc.
Feel free to update the status, either per email here and/or you request a wiki account (email Stefan Reinauer stepan@coresystems.de). We can also upload one or two photos of the board if you can create some and are willing to put them into the public domain (or use CC or GPL).
Uwe.
can you test with the committed r4401? I'd like to get an idea of whether this board works with the new resource allocator.

I've already tested that and didn't see any problems. The bootlog is attached.
