I also tried it on a NanoPi R5S with the patch below:

and it 's partly successful but not quite:
- At boot, I get a U-Boot logo in the top-right corner of the screen.
This apparently gets displayed during the whole time U-Boot is waiting
for BOOTDELAY.
- Nothing else appears on screen (e.g. no text).
- Pressing keys on the keyboard seems to have no effect at all
(including not stopping the boot after reaching BOOTDELAY).
I don't have a serial connection for that SBC, sadly, so I can't post
any further details.
