Make coreboot load VSA from CBFS on amd/gx2.
You have to convert the VSA bios image to ELF using the following
commands (assuming i386/32bit binutils, if in doubt, use crossgcc's
i386-elf-* tools):
objcopy --set-start 0x20 --adjust-vma 0x60000 -I binary -O elf32-i386 -B i386 vsa.binary vsa.o
ld -e 0x60020 --section-start .data=0x60000 vsa.o -o vsa.elf
Then, after build, use
cbfstool coreboot.rom add-stage vsa.elf vsa l
to add it to the image.
