Thanks for bringing this up in IRC.

My guess is this was broken in 2022.04, and fixed in 2022.07-rc5 with
this commit:

commit e744bf3a4ba442a0e9ee1c509c70e1452e3a15d0

    odroid_xu3: Fix board environment variable

    When migrating CONFIG_CONS_INDEX to Kconfig, on this platform we changed
    what "board" evaluated to in the environment.  This in turn meant that
    we would no longer try and find the correct fdtfile via the normal
    distro boot logic.  Fix this by overriding board in the default
    environment, as done on other platforms where CONFIG_SYS_BOARD is not
    what we want to be in the board environment variable.

    Fixes: f76750d11133 ("Convert CONFIG_CONS_INDEX et al to Kconfig")

Could you test 2022.10 from unstable and/or pull 2022.07 from
snapshots.debian.org and test it?
