da21556c35 Major overhaul. 
Removed all the old code for allocation / management of level 1 page
tables.
Implemented new static / dynamic L1 page table allocation  / management
using vm_page_alloc_memory().
Fixed bug in pmap_page_index() when specifing addresses between memory
banks.
Serious cleanup up of the comments

cc3928cd66 arm32 kernel source restructure 
- Major overhaul.
  - Removed all the RiscPC and RC7500 specific code and moved that into
    separate files for the two machine architectures.
  - This routine now provides support for the machine specific machdep
    code and provides cpu_startup().

6aca6ab9a4 Apply Ian Dall's patch from kern/4004. Ian's comment: 
The following patch employs a smarter adaptive polling
	scheme. It also improves the comments, in particular giving
	due credit to Phil Budne for his efforts in nunderstanding
	the device. It also relaxes the pattern for auto config so
	more devices match.

9065e731d6 arm32 kernel source retructure 
- New versions of the drivers for the devices that really are IOMD
    specific. The old arm32/mainbus drivers have either been rewritten
    and are now child devices of the IOMD or they have been restructured
    and split into generic drivers will IOMD specific attachments.

f26efbb3d5 arm32 kernel source restructure 
- These files are not generic or even really mainbus specific.
    They are IOMD specific device.
  - These devices have been re-written as child devices of the IOMD
    device and the new versions will take up residence in the arm32/iomd
    directory with the other IOMD specific code.
