Provided a bus_space implementation for FDT, modelled on bus_space_generic, but with a local version of the map address routine that does a P->V translation, as is the case with NLM's similar routine for XLP. It's not clear to me that this is the right solution -- possibly this belongs in simplebus -- however, it is sufficient to get the DE4 LED driver working. Sponsored by: DARPA, AFRL
