This would set the board to using the control DT, not boot DT.  Is that
what you meant?

But anyway, why not just hard code the FDT path/name here since there is
only one for this board?  I don't see the value in the extra logic of
using the config values (or having a fdt_map).  (Same for beagleplay)
