90448f3f3f 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.

63b59c4db4 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().

7f7429081d Large rototill of the lowlevel code: 
* move all device-specific bitbanging to the device drivers in question --
  i.e., the ip32 init code doesn't access the CRIME registers directly but
  instead trusts the CRIME driver to DTRT.  machdep.c is cleaner thereby.
* introduce int.c, which handles the interrupt-controller goo formerly
  in ip2x.c.
* unify the CPU interrupt handler, with CRIME, INT2, and the various timer
  handlers hooked in via pointers in the platform struct.
* eliminate ip2x.c and ip32.c.  After the interrupt handler cleanup, the
  actual platform-dependent code was so minimal (rev identification, mask level
  initialization) that it made sense to move it into machdep.c
* "#ifdef DEBUG printf("foo"); #endif" becomes aprint_debug.

Tested on my ip22 and ip32.  Discussed with pooka@, rafal@.

ffc95bbe6e As the platform-specific bus reset routine varies based on the memory

74e150c7b1 CRIME revision 1.1 has a bug that affects PIO operations to/from the MACE. 
The recommended workaround is a 5-10ms delay before and after accesses.
Therefore, move the affected bus_space_* operations from bus.h to bus.c
and special-case MACE accesses.

CRIME accesses are not affected, so introduce SGIMIPS_BUS_SPACE_CRIME and
use it as the CRIME tag.

My ip32 seems a little bit happier with this change, and my ip22 didn't
notice the change.

c7e23cc3fe Checkpoint if_mec work (just in case I get hit by a bus). This driver is still 
not operational.  The MII code mostly works, DMA data structures are defined
and allocated, but tx/rx logic is missing.

d6fda0fcbb Rework the memory detection routine to handle cases where kernel doesn't 
fit inside one memory chunk.
Leave 1 page before kernel untouched as that's where our initial kernel
stack before we switch to proc0 stack is (fixes boot problems on my Indy
with small kernels).
