[coreboot] Using as default external monitor for booting in x230

[Car.cuevas]

Hi,

well actually, I will have to use Seabios as payload, since I may be needing sometimes to boot to the windows which came pre-installed, but 99% of times I am using Debian. And actually, my problem is about using as default screen when booting the Bios, because of the FHD mod, the screen which it should be used is the Digital 1 on Dock; the only thing which can be found about this in the coreboot x230 code is:

https://github.com/coreboot/coreboot/blob/master/src/mainboard/lenovo/x230/devicetree.cb#L10

(register "gpu_panel_port_select" = "0" # LVDS)

So should I use there the value 2 or 3 as explained in https://github.com/coreboot/coreboot/blob/master/src/northbridge/intel/sandybridge/chip.h#L33 ?

Thanks

Hi,

I've just flashed my X230 using Linux payload with petitboot. It can
light up the screen when the payload runs without any graphics init
(native gfx or VGA BIOS) in coreboot.

My petitboot payload is built with the buildroot project from Arthur
Heymans[0]. I forked it and updated buildroot to a newer version.
