Setting aside specifics, which I need to get in to later today, please
make sure this passes CI
(https://docs.u-boot.org/en/latest/develop/ci_testing.html) (I saw an
rst error CI would fail over) and do some size comparison before/after
on this series, both when it is and is not enabled. Using
https://source.denx.de/u-boot/u-boot-extras/-/blob/master/contrib/trini/u-boot-size-test.sh?ref_type=heads
can be a handy wrapper around buildman's built-in functionality for
that. Thanks.
