Also USB storage is the canonical way of installing distributions, by
using an USB flash drive with a generic (UEFI) installer on it.

And I second the concerns about removal of UEFI support and USB
keyboard. Especially UEFI is a real deal breaker for ARM64 boards.

So while I see that this series fixes a particular problem, I am a bit
wary of this solution, as this just papers over the issue and will
likely break in the future again.

Can't we somehow fix the environment problem? Possibly via the upgrade
process (save the environment, update U-Boot, re-install the
environment)? Or some other clever way? That would be more future proof,
I believe.

Cheers,
Andre.
