@ -381,6 +381,10 @@ To enable video you must enable these options in coreboot:
- Set framebuffer graphics resolution (1280x1024 32k-color (1:5:5))
- Keep VESA framebuffer
And include coreboot_fb.dtsi in your board's device tree source file, like:
/include/ "coreboot_fb.dtsi"
At present it seems that for Minnowboard Max, coreboot does not pass through
the video information correctly (it always says the resolution is 0x0). This
works correctly for link though.
