Also make TC framebuffer-console search table-driven.
Does not yet include "tcasic" layer; there's no such hardware on DECstations
and nothing for a tcasic layer to do.
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.
a char *, because that's what was really intended, and because
if the print function modifies the string, various things could become
unhappy (so the string should _not_ be modified).
* Add interrupt handler for 3MIN, where we cannot disable TC slot interrupts.
* Change mfbinit() signature to match other (pmax) TC framebuffer init
routines.
* TODO after 1.2: add {cfb,mbf,sfb}var.h. Declare init functions there.
* Eliminate the #ifdef DS5000 and kernel config option DS5000 altogether.
option DS5000 was a hangover from 4.4bsd/pmax; it's never been clear
if it means "support for DS5000/200" or "support for any TC machine".
This implictly fixes pr 1828.
* Use the "tc.h" and NTC generated by config for a "tc? at mainbus"
where appropriate, intsead of #ifdef DS5000.
* Canonicalize the spelling of kernel options that enable support
for particular models. Use
DS5000_25 for the Personal Decstation aka MAXINE aka KN02-ca
DS5000_100 for the 5000/1xx series aka KMIN aka KN02-ba
DS5000_200 for the 5000/200 aka 3MAX aka KN02
DS500_240 for the 5000/240 aka 3MAXPLUS aka KN03
and change DS_5000_xxx to DS5000_xxx everywhere.
* Wrap the interrupt handlers for each model in the appropriate #ifdef,
instead of wrapping all of them with "#ifdef DS5000".
* Wrap the TC autoconfig for each model in the appropriate #ifdef.
the IOASIC attached devices. The DS3100 will now configure properly.
Fix the DS5000/25 IOASIC table entry for the RTC so the RTC interrupts
get enabled.
Fix up a moved include file.
