You could build SeaBIOS yourself externally, and that the result 
`bios.bin.elf` to CBFS by configuring Kconfig to add an ELF file 
(section *Payloads* in the coreboot menu) or by doing it yourself with 
`cbfstool build/coreboot.rom add-payload -n fallback/payload -f 
path/to/bios.bin.elf -c lzma`.
