today I did the usual "zypper -v dup --no-recommends" and the following
reboot stuck in u-boot, it looks like it did no longer like to execute
the GRUB2 EFI binary and instead proceeded to try tftp booting.
Sorry, no serial console on that machine :-(
The machine is right now needed to build stuff in PMBS, so I installed a
raspi-os via network onto an usb stick and copied back just u-boot.bin
from the second, not-updated raspberrypi4 machine, now it is booting again.
No bug report yet, in case nobody else can reproduce it, I'll create one
later tomorrow once the builds finished :-)
