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: 1.3.30; 1.3.38; 1.3.48; 1.3.50; 1.3.52; 1.3.54;

branches: 1.2.16;
Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22364, verified by myself.

branches: 1.1.2; 1.1.26;
Support for the Motorola Sandpoint reference platform using the
MPC8240 processor module. See the README for more information.

__KERNEL_RCSID()

branches: 1.4.6; 1.4.22;
- Change default time frequency to 100MHz from 66MHz.
- Support the serial mode interrupts (with a kernel configuration option)
on the Sandpoint X3.
- Initialize cpu_timebase.
- Enable tulip driver.

branches: 1.3.2; 1.3.6;
Keyboard, mouse, ws*

Enable devices on the SuperIO chip.

Support for the Motorola Sandpoint reference platform using the
MPC8240 processor module. See the README for more information.

Replaced enable/disable_intr by splhigh/splx.

ANSIfy another 1261 function definitions.
The only ones left in sys are beyond by sed script!
(or in sys/dist or sys/external)
Mostly they have function pointer parameters.

Change about 4500 of the K&R function definitions to ANSI ones.
There are still about 1600 left, but they have ',' or /* ... */
in the actual variable definitions - which my awk script doesn't handle.
There are also many that need () -> (void).
(The script does handle misordered arguments.)

Remove all the __P() from sys (excluding sys/dist)
Diff checked with grep and MK1 eyeball.
i386 and amd64 GENERIC and sys still build.

Merge some of the less invasive changes from the vmlocking branch:

- kthread, callout, devsw API changes
- select()/poll() improvements
- miscellaneous MT safety improvements

branches: 1.8.10; 1.8.12; 1.8.18;
Convert sandpoint to GENERIC todr, including breaking of the clock handling
out into its own driver. (NB: mcclock should really, really be an MI driver
to avoid this kind of pasteware, but it is "nontrivial" to cope with the
fact that some machines have different ideas of mcclock.)

branches: 1.7.20;
Remove leading __ from __(const|inline|signed|volatile) -- it is obsolete.

Use char* with mtod() when doing pointer arithmetic on the result.

Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.

mc146818's sc_flag indicates the time is stored in binary format, not BCD.
So we should configure the chip's REGB for binary format as well.
This makes the BeBox RTC finally work reliable for me.

#include <sys/bus.h> instead of <machine/bus.h>.

Don't forget to initialize sc_dev.

Split device_t and softc for MI mc146818 clock,
and other related misc cosmetics.

Move todr_attach(9) calls from each MD attachment to MI mc146818_attach().
