18883bf3fc In itematch(), check to see if the framebuffer PA matches either the 
$Fssxxxxx 1MB slot space documented in the old Inside Macintosh, or the
$Fs0xxxxx 1MB slot space documented in the new IM and Guide to Macintosh
Family Hardware.

ed2ec4869c Update for Chris Demetriou's changes made to the bus.h interface: 
- bus_space_copy -> bus_space_copy_region (for consistency)
- "cacheable" argument becomes a "flags" argument instead, with
  BUS_SPACE_MAP_CACHEABLE and BUS_SPACE_MAP_LINEAR flags currently
  defined.

998d79d26a Add support for DDB (in-kernel debugger) to NetBSD/alpha, based on 
such code for Mach 3's Alpha port.  Initially reworked for NetBSD/alpha
by Chris Demetriou, and then heavily hacked on by me.  Works, but is still
a little rough around the edges.  Known problems:

- Error recovery could be improved a bit.
- Back traces don't work.
- Single-stepping can be flaky, at times.  (Alpha doesn't have hardware
  support for single-stepping, and I'm not entirely convinced the
  MI DDB software-emulated single-stepping logic is 100% correct.)
- Logic for when to drop into DDB needs some improvement.

6f4f08b8b2 Add a few more PALcode operations, as documented in pages (II-B) 2-1 through 
(II-B) 2-33 of the Alpha AXP Architecture Reference Manual, Second Edition:

* rdps - Read Processor Status, needed by spl* functions.
* cflush - Cache Flush
* rdval - Read System Value
* wripir - Write Interprocessor Interrupt Request
* wrval - Write System Value

cflush, rdval, wripir, and wrval are used in multi-processor environments.

7883fba4bf Two video-related changes: 
- Only set mac68k_vidphys if we're on a machine that we couldn't get
   the Mac OS memory map.
 - If we could get the Mac OS memory map, use the framebuffer size found
   by get_mapping() rather than the size calculated using the Booter
   environment.

80e3db443f Apply a change made to other PCI chipsets: 
don't expect/provide pci_decompose_tag to be a MI, public function.  It
wasn't intended to be to begin with, and uses of it (e.g. the one in the
'de' driver) are quite likely to be incorrect.
