Change 219924 by rwatson at rwatson_zenith_cl_cam_ac_uk on 2012/12/30 21:41:52

	In a sign of weakness, replicate the MIPS bus_space_generic.c to
	produce a new FDT version, which will perform necessary address
	space translation for bus_space -- the solution used in NLM's MIPS
	FDT support, but probably not quite the right thing.  This is
	inconsistent with regular I/O via the nexus and the generic
	bus_space, which instead perform translation via pmap_mapdev()
	when a resource is activated.  However, it may work while I
	attempt to identify what the right way to reconcile possible
	approaches.
	
	(Another approach might be to make simplebus use Nexus's activate
	routine instead of a generic one?)
