f15491e9d3 Move the declarations of blockio.S functions from katelib.h to a new, exciting 
<arm/blockio.h>.  katelib.h includes it for compatibility.

7d9a4dbad7 Move blockio.S from sys/arch/arm32/arm32 to sys/arch/arm/arm, since I want to 
start using it on arm26.

hpcarm gets to keep its own version, since it's not identical and I haven't
got an hpcarm box to test.

cbf8e0eb95 Add a files.footbridge for inclusion by cats and netwinder. This is to make moving of the footbridge dir easier (when it eventually moves from arm32) 
Also remove EBSA285 defopt from the netwinder file as the netwinder isn't an eval board.

f9087c439b Move cpufunc stuff from arm32/arm32 to arm/arm. The only change involved is

6a511e05e2 Be consistent with limit constants: 
- use "U" suffix for unsigned constants
 - use "L" suffix for long constants
 - use "UL" suffix for unsigned long constants

mips, powerpc and arm platforms.

fe3c9ceaf7 * Move definitions of exact-width integer types from <machine/types.h> 
to <sys/types.h> and <sys/stdint.h>.
* Add a new C99 <stdint.h> header, which provides integer types of
  explicit width, related limits and integer constant macros.
* Extend <inttypes.h> to provide <stdint.h> definitions and format
  macros for printf() and scanf().
* Add C99 strtoimax() and strtoumax() functions.
* Use the latter within scanf().
* Add C99 %j, %t and %z printf()/scanf() conversions for
  intmax_t, pointer-type and size_t arguments.

1c3a62e066 Sprinkle pmap_update() calls after calls to: 
- pmap_enter()
- pmap_remove()

c3c5158d00 Change the value of tf_pc in undefined-instruction handlers on arm32. It now 
always points to the undefined instruction in question.  It's up to the

continue there.  This is how things have always worked on arm26.

ce5529eabf Change undefined instruction handler to use a linked list for each 
co-processor.  This is necessary so we can have several handlers for
CP0 (used as a catch-all for non-CP instructions).

Handlers are now removed using remove_coproc_handler(), rather than by calling
install_coproc_handler() with a NULL handler.

Because install_coproc_handler() can now allocate memory, there's a version
for use at boot time that doesn't.

3fb058011a Move arm32 ports over to using <arm/armreg.h>, so <cpu.h> mostly contains 
NetBSD-specific definitions.

This also entails some changes to the way CPU identification is done.  I hope
I've got it right.

6f2aa0d0ba Allow "cpu" to have children. In the long term, this may be the best way to 
handle co-processors.  In the short term, it's a necessary hack to get arm26

Note that I'm using __VFP_FP__ to indicate compilation with VFP-format

for this purpose.  __VFP_FP__ was suggested by Richard Earnshaw.

e4cacac41c Storing four-byte pointers to two-character strings is silly. All the 
auxilliary tables used by the disassembler are now char[][].

The main table still uses pointers because:
 - the longest instruction name, "imbrange" is >7 characters long, which would
   make the field length wasteful.
 - GCC spots that most of the formats are shared and makes them pointers to the
   same string, so turning them into char[8] would be counter-productive.
