OpenFirmware is an IEEE 1275-1994 compliant firmware.

It can be used standalone on various targets/architectures, but also as a coreboot payload.

Building

$ svn co svn://openbios.org/openfirmware/ -r720
$ cd openfirmware
$ vi cpu/x86/pc/biosload/config.fth  (patch as needed for coreboot, detailed instructions will follow)
$ cd cpu/x86/pc/biosload/build
$ make

The file ofwlb.elf is your final OpenFirmware payload to be used with coreboot.
