I see you on the list:)

I am under the way of clean up the start.S code, which is the common 
work of every thing,
also some cache and basic configuration work. after that porting will be 
much easier.

u-boot trys to be versatile and small, and some tricky relocation is 
done to place itself on the top of the available ram (which I think I 
don't need). but I think with some modification u-boot can be a payload 
of LinuxBIOS:)
