Add support for the Sun Enterprise 450
Reduce the size of a GENERIC kernel by ~190k
Remove the nasty pointer/bus_space_handle_t casts
Adds debug bus_space code including the ability to trace
bus operations (it actually works now).
The following rules are now followed (and verfified by the debug
code):
1. A "bus_space_handle_t" may only be used with the
"bus_space_tag_t" that created it.
2. Only "bus_space_map()" may create "bus_space_handle_t"s.
3. A "bus_space_handle_t" may not be modified after it has
been created (other than being destroyed by "bus_space_unmap()").
Thanks to help from mcbride, marc, jason, drahn, to anyone that might
have slipped my mind at the moment.
ok jason@, deraadt@
