If a default is selected, please add a blurb in the ocmmit log to
explain why it is orefered over the others, e.g.:

    The IMX8X C0 HW variant is the most widespread, so that's the
    default, but there are a few B0 still circulating so we still
    keep the B0 option for those.

Nitpick: empty line just before 'endchoice'.

This can't happen: the selection is a choice, so at least one is
enabled, and thus IMX_SECO_AHAB_CONTAINER_IMAGE will always get a
value.

It can only be empty when a new choice entry is added, for which no
corresponding default is added for IMX_SECO_AHAB_CONTAINER_IMAGE.
