[coreboot] [ANN] Port of GPL vgabios to gcc

[Kevin O'Connor]

I have made an initial pass at porting the open source vgabios at:

http://www.nongnu.org/vgabios/

from bcc/as86 to gcc.

The new code can be found in the SeaBIOS git repository.  To download
and build the code use:

git clone git://git.linuxtogo.org/home/kevin/seabios.git
cd seabios/
make out/vgabios.bin

The resulting binary can be used on qemu.  For example:

cd seabios/
make
make out/vgabios.bin
cp out/*.bin ../testqemu/
qemu -L ../testqemu/ -hda myimage


This new vga code is still preliminary.  I can start qemu, but there
are known bugs and unimplemented features.

The goal of porting the vga bios to gcc is to make the code more
understandable and easier to modify.  The code could potentially be
enhanced to run on real hardware.  (The current code will only run on
emulators.)
