Welcome to the OpenBIOS project :)  Probably the best way to think about 
it is that coreboot performs the low level hardware initialisation for 
various chipsets and then executes a (generally ELF) payload in order to 
handle the boot process.

In the past I've managed to successfully build CoreBoot with an OpenBIOS 
payload for testing under x86 on QEMU which I think is a good way to 
help get yourself familiar with the process. BTW as a matter of 
interest, do you have any interesting projects in mind for OpenBIOS?

ATB,
