util/vgabios is meant for testing if a certain VGA BIOS binary can/will work if it is included in coreboot. So you need the VGA BIOS to use testbios.
Since the video signal is being generated by the chipset, it seems that coreboot must do some video related chipset initialization prior to running testbios (util/vgabios).
Actually not, testbios can hopefully initialize the graphics using the factory VGA BIOS.
I assume this has been done on a few boards using coreboot v2.
Yes, a few chipsets.
Is there any documentation describing what needs to be done?
In a word: modesetting.
Can anyone describe the status of util/vgabios?
I believe it works, I reused parts of testbios today.
