d94f02f9fd Ok, now we _REALLY_ have Pyxis recognition correct. There are two systypes 
that can have Pyxis: EB164 (AlphaPC164LX and AlphaPC164SX) and DEC_550 (Miata),
and these systypes/variations _always_ have Pyxis.

d6041754c2 Allow the DMA tag to specify a boundary contraint. If the device has a 
more strict boundary, the map will use it, otherwise the map will inherit
the tag's, unless the tag's constraint is 0 (no boundary constraint).

1ef3ca572e - Additional rearrangement for the sake of running on the DECstation some 
day.
- Convert to use bus_dma.
- Fix cleaning up unaligned start address.
- Correctly determine if the device supports Fast SCSI, and adjust the
  minimum sync period accordingly.
- Compute minimum sync period correctly on the 25MHz devices.
- Use GPI2 to determine if we're a 25MHz or 40MHz device.
- Currectly determine SCSI ID and "fast mode enabled" for the built-in
  TCDS on DEC 3000 models, using cached information from the PROM environment.

3aa84f9e26 - Make this into a proper attachment (i.e. use asc_tcds) and clean up 
the namespace accordingly.
- Set FCLK in the CFG3 register if we have a > 25MHz clock.
- Indicate that we support Fast mode to the back-end if we're told we're
  fast by the TCDS layer.
- Correctly compute the minimum sync period.

3b9e9634fb - Change the tcds child locator from "slot" to "chip", making it look less 
like a TurboChannel locator, and more like what is actually going on.
- Allow tcds and asc children of tcds to be cloned.

d3ead78027 Several changes to the TurboChannel Dual SCSI driver: 
- Fix the autoconfiguration model; the TCDS children don't attach to
  TurboChannel, so don't make it look like they do.
- Make the driver use bus_space (not bus_dma yet; soon)
- Recognize the PMAZ-FS (baseboard fast SCSI on DEC 3000s) and the
  PMAZB-AA (TCDS option card) and PMAZC-AA (TCDS fast SCSI option card).
- Rearrange it a bit, so that it can eventually be made into an "MI"
  TurboChannel driver (i.e. work on DECstations).

a2f214a443 Add fine-grained locking, using a locking protocol modeled after the i386 
UVM pmap's locking protocol, written by Chuck Cranor.  Not all of the
support for multiple processors is here yet, but the kernel does run
under moderate loads with LOCKDEBUG (all locking operations are no-ops
unless LOCKDEBUG is turned on).

This is by no means complete... there are still some possible snares
to take a look at.

6626878e7b It is no longer necessary for pmap_pinit() and pmap_release() to be 
pmap interface functions, as NetBSD no longer uses statically allocated
pmaps (except for the kernel pmap, which is special-cased anyhow).

95bdb660ed Simple screen attribute handling for wscons. 
The graphics device driver passes a "default attribute" for normal text
output to the wscons framework. If the emulation module needs more
attributes (for different "renditions") it can allocate them via a
callback.
For now, only the "sun" emulation makes use of it.
