I'm sorry, but I can only confirm your problem. I tried reading those
GPIOs with the coreboot version we had on our RK9 and everything worked
out. After flashing the current upstream version, the VGA output was
garbled. So this is a regression which needs further investigation. I
can't currently work on this, but if you like to bisect the problem:
I guess, commit 11a7db3 should be a working starting point.

Kind regards,
Nico
