769a499800 New bus.h implementation/interface:
- No more distinction between i/o-mapped and memory-mapped
	  devices.  It's all "bus space" now, and space tags
	  differentiate the space with finer grain than the
	  bus chipset tag.
	- Add memory barrier methods.
	- Implement space alloc/free methods.
	- Implement region read/write methods (like memcpy to/from
	  bus space).
This interface provides a better abstraction for dealing with
machine-independent chipset drivers.

6d9ea4cf59 New device attachment scheme:
- split softc size and match/attach out from cfdriver into
	  a new struct cfattach.

	- new "attach" directive for files.*.  May specify the name of
	  the cfattach structure, so that devices may be easily attached
	  to parents with different autoconfiguration semantics.

2c11ad408c convert to use I/O mapping/access macros in <machine/bus.h>.
Mostly mechanical changes, except for probe/attach, which have
to map (and, in the case of probe, unmap) the I/O space that the
chip will use.

3da4b2a160 The IST_* and IPL_* constants are not bus-specific; don't treat them as such.

8a640328ed clean up several ISA device interfaces: autoconfiguration, header
inclusion, and interrupt configuration.  more work still needs to be done,
but it's getting better...

3a7bbb1acd lip service to making ISA support machine-independent. This is the first
round: moving the drivers into a machine-independent directory.
Some drivers (e.g. fd.c) not moved because they use other pc features (e.g.
CMOS settings), and none of the non-driver files moved, because they're
still pretty much PC specific.  eventually (when other ports with ISA
busses really start using this code), more 'high-level' ISA support will
live here.

a0a7429482 lots of changes: prototype migration, move lots of variables, definitions,

definitions.  standardize clock handling.  More changes than you'd want.
