Fix docs on ARM11 MCR and MRC coprocessor commands:
correct read-vs-write; and describe the params.
(ARM920 and ARM926 have cp15-specific commands; this
approach is more generic. MCR2, MRC2, MCRR, MCRR2,
MRRC, and MRRC2 instructions could also get exposed.)

Provide an "armv7a disassemble" command. Current omissions include
VFP (except as coprocessor instructions), Neon, and various Thumb2
opcodes that are not available in ARMv7-M processors.

lean up some loose ends with the ARM disassembler
- Add a header comment describing its current state and uses
and referencing the now-generally-available V7 arch spec
- Support some mode switch instructions:
* Thumb to Jazelle (BXJ)
* Thumb to ThumbEE (ENTERX)
* ThumbEE to Thumb (LEAVEX)
- Improve that recent warning fix (and associated whitespace goof)
- Declare the rest of the internal code and data "static". A
compiler may use this, and it helps clarify the scope of these
routines (e.g. what changes to them could affect).

By enabling this bit, the processor halts when a debug event
such as breakpoint occurs.

Abstract the orion_nand_fast_block_write() routine into a separate
routine -- arm_nandwrite() -- so that other ARM cores can reuse it.
Have davinci_nand do so. This faster than byte-at-a-time ops by a
factor of three (!), even given the slowish interactions to support
hardware ECC (1-bit flavor in that test) each 512 bytes; those could
be read more efficiently by on-chip code.
NOTE that until there's a generic "ARM algorithm" structure, this
can't work on newer ARMv6 (like ARM1136) or ARMv7A (like Cortex-A8)
cores, though the downloaded code itself would work just fine there.

Almost innocuous; this is value is checked later, this
check being wrong would make it check stack garbage.

Also minor fixes for the message from "fill": the byte
count is unsigned, not signed; and more importantly,
print the real number of bytes written

- Itemize the list of private customization examples
for openocd.cfg
- Add "override defaults" as a customization, specifically
for the work area (back it up or relocate it)
- Highlight some work area location issues

Without this it's impossible to use a private config file which
happens to have the same name as an installed one. Say, because
you're bugfixing a private copy...

defining ntrst_delay is pointless; don't.
At least the LM3S3748 eval board doesn't need nsrst_delay
either; remove that too.

that were added after ARMv5TE was defined:
- ARMv5J "BXJ" (for Java/Jazelle)
- ARMv6 "media" instructions (for OMAP2420, i.MX31, etc)
Compile-tested. This might not set up the simulator right for the
ARMv6 single step support; only BXJ branches though, and docs to
support Jazelle branching are non-public (still, sigh).
ARMv6 instructions known to be mis-handled by this disassembler
include: UMAAL, LDREX, STREX, CPS, SETEND, RFE, SRS, MCRR2, MRRC2

With DCCR we are asking the CPU to halt, we should wait until
the CPU has halted before proceeding with the operation.

the ITR register but it will only be executed when the DSCR[13]
bit is set. The documentation is a bit weird as it classifies
the DSCR as read-only but the pseudo code is writing to it as
well. This is working on a beagleboard.

"next iteration" step with the rest of the loop overhead.
Cleanup: remove spurious whitespace, and an overlong line;
only assign "tap->hasidcode" once.
