in my mail to Ross, I guess...)

bb362059ac On Pass 1 Pyxis, disable PCI Read Prefetching, and warn the user about 
the DMA bug that exists on this Pyxis revision.

29977868a7 What was called CNFG in ALCOR and ALCOR2 is actually called PYXIS_CTRL1 
in Pyxis.  Add a comment to this fact.

8f455480ef Tweak the copyrights a little bit. pci_550.h gets a TNF copyright, not 
CMU, and pci_550.c keeps TNF but gets "Andrew Gallatin and Jason R. Thorpe".

cbaedc8675 Support for the Digital Personal Workstation [456]xx, a.k.a. Miata (systype

from myself, and a few more from Andrew Gellatin.

3249813e11 For whatever reason, the firmware seems to enable PCI loopback mode if it 
also enables BWX.  Make sure it's enabled if we have an old, buggy firmware
rev.

d4d49905dd Add support for using BWX for PCI config space and PCI i/o and mem space 
on the ALCOR2 and Pyxis.  BWX is enabled iff:
- It hasn't been disabled by the user (patch `cia_use_bwx' or build cia.o
  with the option "CIA_USE_BWX=0"),
- it's enabled in CIA_CSR_CNFG,
- we are running on an EV5-family processor,
- BWX is in the processor's capabilities mask.

616125f8d1 Deal with a hardware bug in Pass 1 and Pass 2 Pyxis chips. Basically, 
the scatter/gather TLB cannot be invalidated on these chips.  So, to
work around this, we configure the otherwise unsed DMA Window 2 as a
2M SGMAP window at 128M, point all of its page table entries at the
DMA spill page, and, when the TLB is to be invalidated, put the PCI bus
into loopback mode, and create a target hit on Window 2 every 64k for
the number of TLB entries (plus a few ... it seems to not work unless
we read a few extra times), forcing out old TLB entries to make room for
the new, dummy target hits.

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.

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).
