Currently OF bios load fails for a few reasons: - checksum failure - bios size too small - no PCIR header - bios length not a multiple of 4 In this change, we resolve all of the above by ignoring any checksum failures (since OF VBIOS tends not to have a checksum), and faking the PCIR data when loading from OF.
