Thanks for the report, much appreciated! And yes, there is a
regression, I figured this myself already the other week. I sent
https://lore.kernel.org/u-boot/20220316005443.16260-1-andre.przywara@arm.com/

Can you check whether this fixes it for you? Then reply with a
Tested-by:? I will then send the PR in the next days, so that 2022.04
should be fine.

Thanks!
Andre
