2a304686e6 Minor cleanup.
Make the initializer for BAUDLO depend on PCLK directly; it was incorrect on
some ports where PCLK is not 4.9152MHz.
XXX Is the default value actually used?

be1af660c0 Don't set DCD_IE in the frontends. KGDB doesn't even use DCD, and the tty
frontends get it from zsparam() anyway.

3e40b6ff15 A simple, obvious optimization, now that the loop has been
removed from zshard().  Pointed out by Bill Studenmund.

7d09ad09b4 New framework for handling processor interrupts, derived in part from
the hp300 port.

 - Interrupts 3-6 use this immediately.  Interrupt 7 is a special case,
   and the VIA interrupts (1 and 2) will be addressed when that code is
   rototilled.

 - Modify the zs front end to register with the appropriate interrupt
   controller:  through the PSC on the AV Quadras, and direct to
   interrupt 4 on the rest.  Arrange to have the appropriate zsc_softc
   supplied to us at interrupt time.

 - Modify the direct ADB driver (and its PowerManager cousin) to call
   intr_dispatch(), rather than zshard().  XXX This is a kludge, but at
   least limits the brokenness to the ADB drivers, now.

As a side effect, this should fix PR 5590.  Thanks to Bill Studenmund for
correctly determining the cause of the problem reported there.

29f991cc2f Fixup last revision to zs.c. Keep a lot of the comment cleanup, and
keep the explicit clearing of interupts in zscnprobe.

67b0c87dc3 Overkill patches to make serial console work again. Should also make
serial echo work, but not sure. Tested by Paul Goyette.

A few of these changes can probably be backed out, but I'm not sure which.
This part should work for now, and get things going again. These fixes
should also get rid of the problem of things crashing just as zstty0 gets
configured.

5a67b7c680 Add initialization code for cs_wr5_dtr as the M.I. layer now tests
it in initializing during autoconfig. Similar to sys/arch/sun3/dev/zs.c
revision 1.47. Ought to fix hangs at first tty access reported by
Johnny Lam, <jlbg+@andrew.cmu.edu>.

affc68cf0c Work around another bogus uninitialized warning, and fix a legitimate one.
Clearly mark the former.

XXX The bogus warnings show up with -O, but not -O2.  Unfortunately,
    NetBSD/mac68k can't (yet) use -O2.

9b4055eb72 Convert all foo_match() functions to use a `struct cfdata *' for their
second argument.  The NuBus autoconfig code had to be reorganized as a
result of this, and looks much more like a directly-attached bus now.
These changes eliminate __BROKEN_INDIRECT_CONFIG.

debc473329 - Add a ZS_CONSOLE_ABORT option to enable a serial console break to
force a drop to the system debugger.  WARNING:  this used to be the
  default behavior!  Modify custom kernel configs accordingly.
- Check for ZS_HWFLAG_CONABRT in zs_abort(), and don't abort if it's
  not set.

2a73ef60b7 change cfprint_t type definition to take a const char *, rather than
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).
