http://p4web.freebsd.org/@@219924?ac=10 Change 219924 by rwatson@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?)
