real-mode support in U-Boot. The new code allows you to write real-mode code in C - I even have the Linux real-mode printf ported :) This will make writing your own 'BIOS' code for your board a lot easier
FYI - SeaBIOS ( http://seabios.org/ ) uses gcc for real-mode code. Indeed, the name "SeaBIOS" is a play on words - it's a BIOS written in C code.
