Hi!
Starting with revision 1910, latest version of GRUB uses the newly added
Multiboot support in coreboot. If you're using GRUB on coreboot, when you
update to the latest GRUB mind that you also have to be using a recent
version of coreboot.
The main advantage this provides, is that you can now test how will GRUB
for coreboot work on your hardware without having to flash it, and without
having to worry about "bricking" the board. E.g. from GRUB 2:
grub> multiboot /grub.elf
grub> boot
and from GRUB Legacy:
grub> kernel /grub.elf
grub> boot
And following on to that, libpayload based payloads are now multiboot
enabled, so you can load them from GRUB in the BIOS environment of your
choice. I've tried coreinfo on both traditional and coreboot with no
problems. So you can use the above trick to test libpayload payloads
without flashing too. The next step is teaching filo how to load multiboot
payloads, and of course, convincing the desktop distributions to ship
coreinfo.. :)
Thanks to Robert for all his help.

Hello!
Jordan I can create the library that is based on the most recent
revision of libpayload without any problem. But what about creating a
working (or workable) payload from that?
Libpayload is, as the name indicates, a library; a rather limited C
library. You will have to create your own payload that behaves the way
you want it to. There is a sample "hello world" payload in the
libpayload code that can get you started, and you can look at some of
the current active payloads that use libpayload, including coreinfo,
tint and FILO.
