[coreboot] Tryping to support Abit AV8

[Christoph Grenz]

Hello,

I'm currently trying to add support for the Abit AV8 mainboard.
This is also the reason I recently added a patch for integrated POST
displays and W83627HF and K8temp ACPI ASL code to Gerrit.

Now I'm stuck at one point: I could definitely identify the SuperIO
W83627HF and the northbridge AMD K8, but I have trouble with the
southbridge.
lspci shows a "VIA K8T800Pro" host bridge, but flashrom shows a "VIA
VT8237" chipset. 
So now I'm not sure how my devicetree has to look like.
Do I need to support K8T800p (should be similar to the supported K8T890)
and/or do I need the already supportet VT8237?

Outputs from flashrom, superiotool -d, lspci -vv and dmesg are attached.

Thanks,

Christoph
