Actually that seems to be applied in mainline now. Yes USB keyboard works.

It looks like the keyboard needs SPI and there is some sort of linux
keyboard driver, but perhaps not for M1.

OK I see. I did try the USB serial thing but was missing the fact that
U-Boot seems to kill it. So this works fine, thank you will await your
next series. Any way to get U-Boot serial console going in the same
way?
