I’ve rebased the official mender u-boot repo to the upstream’s current main and reapplied my modifications. It compiled without issues.
(note: compiled with CROSS_COMPILE=arm-linux-gnu-)
Booting the new u-boot from sd, it still says no working controllers found:

Using the same u-boot but from ssd (just removed the sd so it falls back to usb), gives this output:
