Split up using BWX for PCI config and bus access. Default to using BWX for
...
the former, but not the latter. Hopefully, this will address some problems
people have been experiencing w/ some devices on Pyxis systems when BWX
is used for bus access. (If it's not used for PCI config access, we can
get fatal machine checks while probing behind PCI-PCI bridges!!)

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.

Use flags instead of a bunch of booleans. Add a "use bwx" flag.

Rework ALCOR/ALCOR2/Pyxis recognition Yet Again. (Actually, just the
...
way it's displayed, and mask off the revision once we've determined
which chip we're talking to.)

If the CIA revision is >= 2, read the CIA configuration register, and
...
remember its contents. Print out a bit of information about the chip,
including whether or not it supports the EV56 BWX instructions.

Treat bus space tags more like pci chipset tags and bus dma tags: allocate
...
them statically within a chipset's state structure, and pass them to
the *_bus_{io,mem}_init() functions.

wholesale update from my NetBSD/Alpha source tree. Includes:
...
Support for AXPpci CPUs,
Support for AlphaStation 600 CPUs,
new boot block structure, which requires an 'installboot'
program and works a lot like the NetBSD/sparc boot blocks.
