I dont get anything on the screen from coreboot. The later os is
displaying fine.
How i build the image: ran on a fresh git cloned (from today) 'make
menuconfig', chose just the mainboard manufacturer and the model, press
esc, confirmed saving, ran 'make'. I installed this image and dont get
any coreboot output on the screen. When i wait long enough, i get the
output from the Linux OS on the screen.
From the coreboot logfile:
coreboot-4.8-1195-gb75a08b199

So it seems to have detected that my screen is 1920*1080. GPU + screen
detection seems to be working. But i dont get any coreboot output on the
screen.
The output had worked fine on this screen with the OEM BIOS.
