re: bus_space_physload(9)

i don't understand why you think framebuffers are mapped uncacheable.

your proposal appears to provide no benefit for anything currently
supported, and i'm not sure why bus_space_physload() needs to be
in the bus_space domain, rather than plain UVM.  your XIP use-case
may be valid -- i haven't considered it heavily -- but the fb one
appears to not be useful.
