1d9c166f51 - removed obsolete ppc_exit/ppc_boot functions 
- OpenFirmware returns overlapping memory regions. Use a simple
  brute force algorithm to merge these into non-overlapping
  regions. This fixes bugs in reporting of available memory
  and also prevents pages from being added twice in the VM system.

eaa53cc8fc Use the "shut-down" and "reset-all" Forth procedures to halt and 
reboot, as calling OF_exit() just hangs a mac.

FreeBSD on my G4 800Mhz mac behaves identically to OSX for halt
and reboot now.

31c82d0332 Get the correct memory regions from OpenFirmware. We were getting the 
"available" ranges, not the "physical" ranges.  Clean up some of the
bootstrap code in the process.

5244eac968 Complete rework of the PowerPC pmap and a number of other bits in the early 
boot sequence.

The new pmap.c is based on NetBSD's newer pmap.c (for the mpc6xx processors)
which is 70% faster than the older code that the original pmap.c was based
on.  It has also been based on the framework established by jake's initial
sparc64 pmap.c.

There is no change to how far the kernel gets (it makes it to the mountroot
prompt in psim) but the new pmap code is a lot cleaner.

Obtained from:	NetBSD (pmap code)
