Hello coreboot
These initial patches enable booting with the SeaBIOS VGA BIOS on
Geode LX hardware.
corebootv3-vga-msr.patch
adds 3 vga legacy io routing msrs
seabios-vgarom-geodelx.patch
adds geodelx specific functions to the vgabios
The rom will run from either coreboot/vm86 or SeaBIOS. When finished
"GeodeLX GPL VGA BIOS" should be displayed on the screen.
My test hardware is an Artec Group DBE-61. I have successfully
built and used the rom with gcc-4.1.2/binutils-2.17 and
gcc-4.3.3/binutils-2.18. VGA functionality has been tested with the
linux vga console, svgalib utils, libpayload vga driver and SeaBIOS. I
have also confirmed that linux lxfb and Xorg function correctly after
the rom is loaded.
