Enable Bluetooth support.
usbdevices.config includes support for USB Bluetooth.
Tested on an o2 with a PCI USB adapter and Broadcom BCM20702A0 dongle.

switch sgimips to common bus_dma and bus_space in arch/mips/
Tested on O2 and Indy.
Things that are compile-tested only for lack of hardware:
- GIO ethernet cards with PCI bridges
- IP2x hardware not found on Indy
- IP1x

Deal with arcbios calls being O32 and kernels being N32/N64.

Use bus_dmamem_common.

Enable Personal IRIS 4D/20 and 4D/25 support:
- Adapt int(4) to handle the INT1 chip
- Move generic rtc clocks out of hpc/ and into dev/
- Handle the very strangely wired eeprom and other bits in arcemu
- Sprinkle MACH_SGI_IP6 as necessary
- Enable IP6/IP10 devices in GENERIC32_IP12. Yes, the naming is poor but
there's no winning with kernel/hw compatibility on sgimips...

Tested on my 4D/25. Doesn't (appear to) break macallan@'s IP22.

Since files.wscons et al. are included by ~all ports anyway, include
them in the mi "files" file, and remove include statements from md files.
These shouldn't pull in additional kernel code when not in use, so it
shouldn't do any harm except a risk of namespace collisions which
should be easy to fix.

Interrupt handling changes, in discussion since February:

- Reduce available SPL levels for hardware devices to none, vm, sched, high.
- Acquire kernel_lock only for interrupts at IPL_VM.
- Implement threaded soft interrupts.

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: 1.44.8; 1.44.10;
make the delay()s and spl*()s in bus_space*() functions optional

sgimips converted to timecounters. Systems that can do them get mips_cp0
based logic. We also use the common mips3_clock functions for those systems,
removing some port-specific code.

Abstract the interface between pckbc(4), and the pckbd(4) and pms(4)
drivers that attach to it. This allows for other host interface chips
that use the same keyboards and mice, such as the ones in the ARM
IOMD20, ARM7500, and SA-1111. The PC-compatible driver is still
called pckbc(4), and the new abstraction layer is "pckbport", so the
child devices have moved from sys/dev/pckbc to sys/dev/pckbport, which
also contains some code shared between all host controllers. To avoid
incompatibility, pckbdreg.h is still installed in
/usr/include/dev/pckbc.

In theory, this shouldn't cause any behavioural changes in the drivers
concerned. Thy just use rather more function pointers than before. Tested
on i386 and (with a new host driver) acorn32. Compiled on several other
affected architectures.

Completely remove IP2X and IP32, which renders opt_machtype.h obsolete.

Attach int0 at mainbus (precedent being the ip32 CRIME device, which handled
interrupts and timer calibration yet is also attached at mainbus).

Introduce the INDY_R4600_CACHE config option, which more accurately describes
the code enabled by this option.

This renders #ifdef IPxx completely obsolete, thus we theoretically can unify
the GENERIC files if a workable load address relocation scheme can be found.

Following the example of the hpc/, gio/, and ioc/ directories, move the
mace devices to their own mace/ directory. Alter conf/files.sgimips to
reflect this change in a sane manner (i.e., pull in dev/files.dev and
mace/files.mace when appropriate).

At the same time, allow crime_intr_establish() to fall through to
mace_intr_establish(). mace devices now call cpu_intr_establish().

ip2x.c and ip32.c are no more.

Add pic attached at mainbus (for IP12).

Part two in the Great Renaming. ip22.c becomes ip2x.c, and all generic ip2x
routines become ip2x_*.

Change all IP22 preprocessor conditionals to IP2X preprocessor conditionals.

Part one of two -- part two will be renaming ip22_*() to ip2x_*().

Add ioc driver to IP2x config file, pull in ioc/files.ioc as well. Note that
IP2x now has blinkenlitzen.

Compile sgimips/ip[23]2.c iff the corresponding IP[23] is defined in the
config file.

Add ip20.c

Rationalize config file scheme. Discussed at length with rafal@, pooka@, soren@.

Apply a bunch of patches written by Christopher SEKIYA
(with several cosmetic changes by me) which fixes O2 (IP32) support.

Now my R5000 O2 works fine in multiuser with on-board AIC7880 SCSIs
and several PCI network cards (but only on serial console yet).
L2 cache on R5000/Rm5200 is still disabled for now, but it will be
fixed later, hopefully.

See recent discussion on port-sgimips for details.

Use common mips generic software interrupt routines.

Changes from Izumi Tsutsui, tested by Havard Eidnes.

Since everyone uses clock_subr.c (or should, if they don't currently),
list it in conf/files instead of in every port's files.*.

now that mem_no is emitted by config(8), there is no reason to keep
copy of more or less identical iskmemdev() for every arch; move the function
to spec_vnop.c, and g/c machine-dependant copies

Merge the gehenna-devsw branch into the trunk.

This merge changes the device switch tables from static array to
dynamically generated by config(8).

- All device switches is defined as a constant structure in device drivers.

- The new grammer ``device-major'' is introduced to ``files''.

device-major <prefix> char <num> [block <num>] [<rules>]

- All device major numbers must be listed up in port dependent majors.<arch>
by using this grammer.

- Added the new naming convention.
The name of the device switch must be <prefix>_[bc]devsw for auto-generation
of device switch tables.

- The backward compatibility of loading block/character device
switch by LKM framework is broken. This is necessary to convert
from block/character device major to device name in runtime and vice versa.

- The restriction to assign device major by LKM is completely removed.
We don't need to reserve LKM entries for dynamic loading of device switch.

- In compile time, device major numbers list is packed into the kernel and
the LKM framework will refer it to assign device major number dynamically.

* Move the mii_bitbang attribute into dev/mii/files.mii
* Pull in dev/mii/files.mii from conf/files, rather than playing
the magic "files include order" dance in N machine-dependent
configuration definitions.

All the mips ports had an identical procfs_machdep.c, so use a common
file under arch/mips/mips.

- convert usage of "defopt" to "defflag" where the relevant option does
not support a value (e.g., it's to be used as "options FOO" instead of
"options FOO=xxx"). options that take a value were converted to
defparam recently.
- minor whitespace & formatting cleanups

O2 RTC attachment, based on code from Antti Kantee.

- replace "defopt" with "defparam" for options which must take a value,
as config(8) will warn for value-less defparam options
- minor whitespace/formatting cleanup
- consolidate opt_tcp_recvspace.h and opt_tcp_sendspace.h into opt_tcp_space.h

cleanup:
options SPACE TAB
makeoptions TAB
psuedo-device TAB
remove trailing whitespace
replace multiple spaces -> tabs
options "FOO" -> options FOO
options "FOO=bar" -> options FOO=bar
options "FOO=\"bar\"" -> options FOO="\"bar\""
