[coreboot] VGA Option ROM

[Wolfgang Kamp - datakamp]

Hi,

I found a problem with VGA ROM initialization on the AMD  Inagua or Persimmon Board with coreboot and seabios.
If I configure coreboot to scan for VGA ROM, it finds the VGA device and runs the VGA ROM from CBFS.
Later seabios also finds the VGA PCI device and runs the VGA ROM too, so it gets double initialized.
In my case this seems to be a problem, because the DisplayPort to LVDS converter chip gets confused.
If I configure coreboot not to run option ROMs, seabios  does not find  the VGA PCI device (1002:9804).
So option VGA ROM will not be executed.
I have attached two logs which shows the problem in finding the VGA device.
Can anyone help me?

Regards

Wolfgang
