I was asked to post it here too.

I would like to announce that I was able to boot Linux using u-boot on AMD64 
motherboard Asrock 939A785G. The development was done on QEMU.

How does it work?

Coreboot does the complete HW init including memory setup PCI etc. When finishes 
it loads u-boot.

Coreboot is free software replacement for BIOS, but unlike BIOS it only does the 
hardware init (and ACPI). A payload needs to be executed which does something 
useful for the user (like a linux kernel, SeaBIOS, FILO, grub etc)

You can read more about coreboot on http://coreboot.org

How the porting was done is described here:

This project started "just for fun" or "because I can". Maybe there are some 
real uses. If you can think of some, please let me know.

Anyone with more free time could work on this?
