Dear maintainers,
U-Boot on my Odroid U2 fails to initialize as of commit
e44d7e73fe0d649693d8d0a110cd7632bc919273 (introduced after
v2022.10). I
get the following output:

This repeats indefinitely. 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.
board_late_init() is presumably enabled with CONFIG_BOARD_LATE_INIT
and the code in board/samsung/common/board.c is being called.
-96 is -EPFNOSUPPORT which means that the CROS_EC uclass is missing.
So either enable CROS_EC so you have the uclass, or disable
BOARD_LATE_INIT so it doesn't matter.
Best, Joost

Hi Simon,
Thanks. Both solutions work. With `CROS_EC` enabled
`uclass_first_device_err(UCLASS_CROS_EC, &dev)` returns `ENODEV`. Since
`board_late_init()` seems to do legitimate work for this board
(defining the `mmcbootdev` environment variable) I think enabling
`CROS_EC` is the way to go. Should this be part of the defconfig for
odroid? If so, I can send a patch.
Best, Joost
