[coreboot] Epia ME6000 VGA

[Michael Rauscher]

Hi,

I ran into problems to enable VGA in coreboot on the ME6000.

Error! malloc: free_mem_ptr >= free_mem_end_ptr

The whole thing is stored in a 39SF040 (512 KB), so I've set the rom_address to
0xfff8000:

device pci 0.0 on  # PCI
        chip drivers/pci/onboard
                device pci 0.0 on end
                register "rom_address" = "0xfff80000" #512k image
        end
end

(I've also tried to create a 256 KB image (prepended with 256 KB of 0s) with
fffc0000 - same effect).

The following options are used:

option CONFIG_CONSOLE_VGA=1
option CONFIG_PCI_ROM_RUN=0
option ROM_SIZE=458752

The fallback size is set to the same value as the ROM_SIZE (458752) as I use a
fallback-only image.

The interesting things are:

1. It doesn't matter if I use OptionsRom or the legacy VGA-BIOS
2. Without VGA BIOS (configuration adapted) it works.

Any suggestions?

Thanks in advance

Michael
