I recently merged Boris Brezillon's patches to move new boards outside
arm/Kconfig. Patches were related to MX6, but the same mechanism can be
reused for MX5/MX53. It should be better to have the same and bew boards
should not change arm/Kconfig. That generates conflicts by merging
different architecture.

Can you take a look at it and move USB armory to that approach ?

If I understand well, board does not boot without ESDHC. You could then
drop the #ifdef as CONFIG_FSL_ESDHC *must* always be set.
