Dear maintainers,
As of commit 4a3ea75de4c5b3053eac326bf1c753ed65df8cb9 (somewhere
between v2021.07 and v2021.10) U-Boot on my Odroid U2 can't read files
from an SD card (despite being loaded from the SD card itself). During
initialization loading the environment from the SD card fails (NOTE:
the environment is zeroed):

In the U-Boot shell, running `ls mmc` and `load mmc` fails:

I'm building U-Boot using the default config for board `odroid` and
boot the Odroid from an SD card with firmware (`bl1`, `bl2` and `tzsw`)
from Hardkernel's clone of the u-boot repository [1]. There are no
peripherals connected apart from the SD card and the serial console.
Please let me know if you need more information.
Best, Joost
