Define __HAVE_LEGACY_INTRCNT to indicate this port uses legacy intrcnt
interrupt accounting.

branches: 1.20.110; 1.20.112;
Now that __HAVE_TIMECOUNTER and __HAVE_GENERIC_TODR are invariants,
remove the conditionals and the code associated with the undef case.

branches: 1.19.2; 1.19.8;
Merge the ppcoea-renovation branch to HEAD.

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree. Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches. The work
for this branch was done by a variety of people, too long to list here.

TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.

NOTES:
pmppc was removed as an arch, and moved to a evbppc target.

branches: 1.18.10;
Generic soft interrupts are mandatory.

branches: 1.17.2; 1.17.10;
MI softintr(9)'fy.
Probably problematic, but LC630 is running at single user.

branches: 1.16.4;
Add Timecounter support for mac68k, using the otherwise idle second
timer of VIA1. Passes regression/sys/kern/time regression test.

While we are here, GC leftover prototypes from MI todr integration,
and clean up clockreg.h in the light of "Guide to the Macintosh
Hardware" information.

(Reviewed and okayed by Martin Husemann)

Convert mac68k to generic todr. Thanks to Robert Swindells for testing.

branches: 1.14.20; 1.14.22;
merge ktrace-lwp.

branches: 1.13.8;
mac68k no longer abuses cf_unit.

branches: 1.12.16; 1.12.24;
Use "#define<tab>".

branches: 1.11.8; 1.11.12;
add __BROKEN_CONFIG_UNIT_USAGE #define, becuase these ports do very
wrong things with device configuration data "cf_unit" information.

branches: 1.10.22; 1.10.30;
Remove __BROKEN_INDIRECT_CONFIG, since we are no longer broken.

First step inn removing config_scan() and the hacks that gave devices
on indirect-config busses a (permanent) softc that they could share
between 'match' and 'attach' routines:

Define __BROKEN_INDIRECT_CONFIG so that old autoconfiguration
interfaces are used, until drivers are converted to use the new
interfaces (actually, converted back to use the _older_ interfaces)
which prohibit indirect configuration devices from receiving a softc
in their match routine that they can share with their attach routine.

Prototype for -Wall -Wstrict-prototypes -Wmissing-prototypes -Wno-uninitialized
Also change the device probing scheme to use something a bit more rational.
A current side-effect is that nubus cards are double-mapped. I expect
to fix that shortly.
Also change splclock() to block everything but serial hardware interrupts.

Remove this define--we're using the new dump type.

define __BDEVSW_DUMP_OLD_TYPE for ports where it's true. clean up
some m68k ports inclusion of common header.

new RCS ID format.

add comment for consistency.

Fixup to use m68k headers, now. Thanks, Chris.

Added signal.h for -current. The rest is formatting changes.
