Update of /cvsroot/src/sys/arch/mac68k/dev
In directory netbsd1:/var/slash-tmp/cvs-serv18044/dev

Modified Files:
	grf.c grf_mv.c grf_subr.c grfvar.h if_ae_nubus.c if_sn_nubus.c 
	nubus.c nubus.h 
Log Message:
Implement new NuBus slot space mapping/probing code, utilizing bus.h (and
our MD bus_space_probe() extension).  This has several side effects:

 - NuBus drivers must map and unmap slot space, rather than relying
   on this happening before they are attached.
 - Functions exported to NuBus drivers from nubus.c now need to be
   supplied with a bus space tag/handle pair.
 - Old bus map/peek functions can be garbage collected, as can pmap
   support for the same.

Because of some current limitations of the bus space specification, we
are violating the abstraction in grf_mv (NuBus grf driver).  All such
violations are clearly marked /* XXX */, and must be addressed when
the specification is updated.
