... Could you give me a bit more hints or point where to start? I've tried to build sandbox, but it fails for v2021.01 release (I've did make sandbox_defconfig && make all). I assume I would need to add adc and adc-keys devices to some sandbox dts and some code triggering and checking the key values, but that's all I know now.
Well you do need to be able to build sandbox or you will get nowhere...what error did you get? Once we understand what went wrong we can update the docs. Maybe it is missing a dependency.

This is pretty mysterious. Are you sure you are using an x86_64 machine?
I've finally found what caused the issue on my build system. It is x86_64 machine, but after some old cross-builds I had an 'asm' symlink in u-boot/include directory pointing to arch/arm directory. I'm quite surprised that it has not been removed by make clean/distclean/mrproper combo.
Best regards
