Building coreboot

$ svn co svn://coreboot.org/repos/trunk/coreboot-v2
$ cd coreboot-v2/targets
$ ./buildtarget nec/powermate2000
$ cd nec/powermate2000/powermate2000

Now copy your payload into the current directory and name it payload.elf. Then, type:

$ make

You can now flash the resulting coreboot.rom on a ROM chip using Flashrom.
