Hi Richard,
I tried to build coreboot for VIA vx8xx and found that there is a lot of definitions are missed in submitted source code. It look that OLPC developers had their own config files with stuff like VIACONFIG_xxx and FULL_ROM_SIZE defined in it. But those configs were not submitted in coreboot. Also definition VX855 PCI device IDs are missed. It would be nice to have those definitions submitted in repository.
Thank you, Konstantin Lazarev
