I don't think that anybody tested FITs on ARM.  On the other hand, the
concept is generic, so _should_ be no real show stopper on the road.
Otoh I would not be surprised if there are some minor problems waiting
for you to find them....

For a start I'd try to include "CONFIG_FIT" in your configuration ;)

Cheers
