Those are AMD boards. What type of configuration would I be looking for on an Intel Skylake laptop?
Presently, I've been trying Intel FSP 2.0's GOP driver with a near-stock VBT and including VGABIOSes for both cards to boot a UEFI payload. Do your patches work with the GOP driver initialising the display or would I need to have coreboot run the OptionROMs?
Does this depend on where the display is wired up to? I don't know how APUs are set up with a dGPU.
The trouble, of course, is the devicetree settings. I wouldn't know what to set "PrimaryDisplay" to.
Regardless, thanks for your help.
