+ This enables the 'ut overlay' command which runs a series of unit
+ tests on the fdt overlay code.
+ If all is well then all tests pass although there will be a few
+ messages printed along the way.
+ Be warned that it requires an out-of-tree dtc compiler with patches
+ to support the DT overlays, otherwise it will fail.
