The crmfb device does not depend on iic; i2cbus and i2c_bitbang is
sufficient, says jmcneill@
Fixes a build problem for (at least) the GENERIC32_IP3x kernel.

crmfb may run in more than 8 bit now so we need the other rasops* as well

crmfb needs edid and friends now

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.

branches: 1.9.20; 1.9.28; 1.9.34;
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.

Add crmfb, a framebuffer console driver for the onboard O2 video (SGI-CRM)

branches: 1.6.8; 1.6.12; 1.6.14;
Add pic and imc-specific functions to alter the GIO bus arbiter
configuration. These are to be used exclusively by a higher interface in
gio/gio.c.

Also add functions to enable, disable and query the state of SysAd bus
parity detection since certain gio(4) cards need to be able to disable
it in order to work around their own buggy implementations.

branches: 1.5.4; 1.5.8; 1.5.18;
merge ktrace-lwp.

TAB/space cleanup.

Add support for keyboard and mouse attachments at zs*, used on IP12 and IP20.
Code written by Steve Rumble; committed with his blessing.

Using a glass TTY as a console on IP20 (IP12 untested) should now be possible.

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.

Add files.dev and files.mace
