[coreboot] coreboot 4772 & PCI ROM's errors and warnings

[Gelip]

I noticed a strange debug serial log. I have cloned and make crossgcc coreboot 4772 on debian 6.0.5.
- if build coreboot with default payload (SeaBIOS 1.7.2.1) have no errors and warnings
- if build coreboot with set payload to None then have errors and warnings:
========================================================================================

- if build coreboot with set payload to None and manually add SeaBIOS (the same version or new) like this:

./build/cbfstool build/coreboot.rom add-payload -f build/seabios/out/bios.bin.elf -n fallback/payload -c lzma

still the same errors and warnings. What is it ???

I use make distclean to test new build.

Although errors WinXP boot and working OK, my NIC RTL8139 working OK
