49d5ae18ba Call pci_1000a_pickintr() like on other platforms, but for 1000a expand 
the iot, memt, and pc in the call so that pci_1000a_pickintr() (and the
other routines in that module) do not need to be aware of the core logic
type just to pass down memory and I/O space tags or to call the decompose
function.

92aafa4a46 Identify ST_DEC_1000A as PCI/EISA. 
New macros:

	LOCATE_PCS(struct rpb *hwrpb, int cpu_number)
	PCS_PROC_MAJORTYPE(struct pcs *)
	PCS_PROC_MINORTYPE(struct pcs *)

Define LOCATE_PCS() to map (hwrpb, cpu_number) -> Per-Cpu-Slot structure.

Replace the PCS_PROC_{MAJOR,MINOR}{,SHIFT} stuff with macros that simply
return the major and minor cpu type codes.

1fbd0b3749 GC the unused `physadr' type, which was not able to hold a complete physical 
address on 2 architectures anyhow.  Also, move the definition of the `label_t'
type inside _KERNEL protection, since it is specific to the in-kernel
setjmp()/longjmp() implementations.

651b44e211 Rework the way kernel include files are installed. In the new method, 
as with user-land programs, include files are installed by each directory
in the tree that has includes to install.  (This allows more flexibility
as to what gets installed, makes 'partial installs' easier, and gives us
more options as to which machines' includes get installed at any given
time.)  The old SYS_INCLUDES={symlinks,copies} behaviours are _both_
still supported, though at least one bug in the 'symlinks' case is
fixed by this change.  Include files can't be build before installation,
so directories that have includes as targets (e.g. dev/pci) have to move
those targets into a different Makefile.

53394a1d41 Change the ISA DMA API to take an isa_chipset_tag_t rather than 
a struct device * corresponding to the ISA bus device.  The ISA DMA
controller driver functions have been renamed and now take a struct
isa_dma_state *, and are called indirectly by machine-dependent code
which provides the DMA state.

These changes allow e.g. `ofisa' (the OpenFirmware configuration
mechanism for the ISA bus, used by e.g. Sharks) to use the MI ISA
DMA controller code.

f5cd6a7736 Add debugging support to the bus_space macros. If BUS_SPACE_DEBUG (or DEBUG) 
is defined, the bus_space macros will check to ensure that the bus address
and the target buffer (if applicable) are aligned properly for the size
of the type being used.  If they are not, a message will be displayed on
the console.

Strict alignment is required by the Alpha architecture, and a trap will
occur of unaligned access is performed.  These changes will aid debugging
of broken device drivers.

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.

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.

may be called in other situations where the memory situation is desperate,
although it's more likely that the pages will simply be needed again the
next time a process runs.

3ac5a77c70 Make pmap_kremove() deal with mappings entered with pmap_enter() as well. 
Prevents stale PV entries from lingering around.  Fixes a nagging
"kernel stack not valid halt" I was seeing with PMAP_NEW.

Idea from Chuck Cranor.

3786a63843 1. Always link at the high address, now that we can use free ram below 
the kernel on most platforms, including all of the entry-level platforms.
2. Kill the comments and options for load address selection.
3. Kill the default -g.

49408401a3 In pmap_destroy_lev1map(), fix a problem where the pmap's ASN wouldn't 
be invalidated if the pmap is not active.  A rare thing (in fact, I'm
having trouble thinking of a scenario where it would happen), but it was
incorrect, nonetheless.

a26a53fbbc Slight hack to allow the MI SCC driver to be used at cdev major 15 
for testing purposes.  Normal kernels still get the Alpha-specific
SCC driver.

ee83014c4d Initial mostly-working ioasic attachment for the MI 8530 SCC driver. It is 
enough to use as a console on my DEC 3000/400 (connected to a VT-520
terminal).

XXX The MI SCC driver needs serious changes to handle platforms which
have muliple SCC attachments (e.g. the Alpha port, which has an ioasic
attachment for TurboChannel systems and a gbus attachment for TurboLaser
systems).

XXX The MI SCC driver also needs changes to deal with the wacky (to put
it mildly) way the chips are wired up on the ioasic (on both TC Alphas
and DECstations).  These are going to come along later.

up front. Do the spacing arithmetic slightly differently.

8e5970917e Redo it slightly so that S/G now appears to work a bit better. This 
version has 2GB direct map starting at 2GB, and either 256MB or 1GB
S/G starting at 1MB. I've done *some* testing on this, but I'm not
quite happy with it yet.

66194d05bc Do a more complete job of figuring out what kind of DWLP? we have- figure 
out how much s/g ram is available. Can't really use the 128K entry S/G
ram yet- but I'll fix that later. More importantly, add in a dwlpx_iointr
handler that will try and figure out what the DWLPX error is and at
least print out what is happening- I actually found it useful in S/G
entry debugging as it could tell me that I had some bad S/G entries.

d3d99a28c9 Update #ifdef'ed-out changes from pmax : 
* Add more #ifdef pmax/#endif, #ifdef alpha/#endif where appropriate.
    Config and heade files need more work (or replacement)
  change TK_NOTYET to HAVE_RCONS
  change commented-out /* && cn_tab.cn_screen */ to && raster_console()
  * Add DDB hooks.
  * Note where Alpha console ignores carrier on consoles.
  * Add pmax-derived console tty-size code inside HAVE_RCONS
  * Fold in gross pmax rcons-input hooks, inside HAVE_RCONS

Untested, but whitespace/ifdef only,  cross-compiles OK,
preprocessing shows no significat differences (famous last words)
