pvlists if they were entered by the fault routine. in this case
we had better call pmap_remove to clear out the pventry structures.
appears to fix some pvlist releated panics people have seen with pmap.new.
Replace all DS5000_* and DS3100 ifdefs with ifdefs on DEC_ options.
* Use MI declarations, not pmax-specific, in model-specific init
that uses baseboard (ioasic) registers.
* Further cleanup of machdep.c. Clock-tick still needs more thought.
* Use 'ibus' names for 3100 baseboard devices in MI code.
* add "Platform" support inpmax/pmax/sysconf.c and pmax/include/sysconf.h
(based on Alpha cpuconf.[ch], with a namechange to avoid clashes with
support for models of MIPS cpus. They differ more than Alphas).
* For each supported model of DECstation, create a separate file
with the support for that model. Use model codenames, since
support is really baseboard-specific and CPU daugherboards can change.
Move code from machdep.c and pmax_trap.c,
Add sysconf (nee "cpuconf") support.
* Rename model-specific functions to match sysconf names.
* Clean up autoconf.c. Use platform callbacks.
* Retire pmax_trap.c.
Leaves I/O bus configuration and console configuration untouched.
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.
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.
as pmax/dev/findcons.c:
* Follow the same logic: look for the device the PROM is using.
* If it's a framebuffer and we don't have a driver for it, try other
* framebuffers in PROM search order.
* If no match found, warn user and fall over to serial console.
* if no serial console found, go back to PROM.
Rework tc/scc.c attach routine to give cleaner initialization semantics.
Prune out old 'braindamage' code.
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.
* Do rcons output properly, using cn_tab->cn_dev which points
at rcons cdevsw entrypoints.
* The pmadx console code was using keyboard (serial) device
(major,minor) for raster consoles with special code in the keyboard
drivers to catch output intended for consoles, pull it off the device
queue, and print them via cnputc().
Ifdef out RCONS_BRAINDAMAGE.
* Other minor cleanup to pmax scc driver.

quite happy with it yet.
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.
certain 17" monitors. Change from Michael R. Zucca, PR 4988.
XXX - This can cause problems on system with the DAFB chip which currently
use only a NuBus-based video adapter. In particular, grf devices may not be
attached properly in this case. This unfortunate situation is less annoying
than not having a reasonable console, however. A reasonable, reliable
monitor sense algorithm for the DAFB would resolve the problem.
