Guys I just figured it out, I had to update my .config with following change:

CONFIG_INTEL_GMA_VBT_FILE="src/mainboard/$(MAINBOARDDIR)/data.vbt"
to:
CONFIG_INTEL_GMA_VBT_FILE="src/mainboard/$(MAINBOARDDIR)/variants/t430s/data.vbt"

Hello,

I cannot compile git coreboot anymore for T430s, my last successful compile is from Nov 12, that is the last time that I flashed my laptop with fresh git coreboot. Since then I have not changed anything on my end except usual 'git pull; git submodule update --init --checkout; make nconfig (I would simply save to update my .config file); make'

This is the error I'm getting (it is actually after running 'make' for 2nd time since it prints less info)

[kyle@ROG ~/coreboot (master)]$ find src/mainboard/lenovo/t430s -name data.vbt
src/mainboard/lenovo/t430s/variants/t430s/data.vbt
src/mainboard/lenovo/t430s/variants/t431s/data.vbt

Is the data.vbt in wrong place by any chance?

I was looking at output of 'git log src/mainboard/lenovo/t430s' and noticed that on Nov 29 support for T431s was added. Maybe this has to do something with it?

Thank you.
