[coreboot] No video output with Bay Trail

Thu Jan 8 16:19:21 CET 2015

Fred, as long as the video output in Linux environment, it seems the video
controller is configured properly, so maybe something wrong in seabios in
configuring video to text mode (I remember seabios will configure video to
text mode as default, correct me if I am wrong).

I would suggest you enabling Boot Splash in coreboot, you might be able to
see the boot splash photo show up on your monitor.

Another suggestion, maybe you should check install_intel_vga_int15_handler
routine referring other coreboot projects and see how to modify/port it to
your project.
