If the MEM-AP cache is invalid, don't display it; just report that
invalidity as an error. (This bug has been observed with "mdw 0 32"
after just a "reset halt". Some code is being wrongly bypassed...)
If it's valid, display that cache at DEBUG level, not ERROR. Also,
don't assume it's an AHB-AP; it could be another flavor of MEM-AP.

Reject invalid AP numbers (256+) as Tcl operation parameters.

Add my copyright to the ADIv5 code (multiple contributions).

Make messages reference "DAP" if they're actually transport-agnostic, or
"JTAG-DP" when they're JTAG-specific. Saying SWJ-DP is often wrong (on
most Cortex-A8 chips) and is confusing even if correct (since we don't
yet support SWD).
Rename a JTAG-specific routine to jtagdp_transaction_endcheck() to highlight
that it's JTAG-specific, and that identify DAP clients undesirably depending
on JTAG. (They will all need to change for SWD support.)
Shrink a few overlong lines of code. Copy a comment from code removed
in a previous patch (for the ARMv7-M "dap baseaddr" command).

Add space missing after the invalid ACK value. On init, say
which AP is being used, and don't assume it's an AHP-AP.

Don't just complain about an invalid ACK; say what the
value was, to help troubleshooting.

Add doxygen and other comments for what's more or less the lowest
level JDAG-DP primitive, to access JTAG_DP_{A,D}PACC registers.

Provide helptext which was sometimes missing; update some of it
to be more accurate.
Usage syntax messages have the same EBNF as the User's Guide;
there should be no angle brackets in either place.
Don't use "&function"; functions are like arrays, their address
is their name. Shrink some overlong lines, remove some empties.
Add a couple comments about things that should change: those
extra TCK cycles for MEM-AP reads are in the wrong place (that
might explain some problems we've seen); the DAP command tables
should be shared, not copied.

JTAG has only two possible JTAG ack codes for APACC and DPACC
register reads/writes. Define them, and remove empty "else"
clause in the code which now uses those codes.

I think some of these assumptions are not well-founded.
Related, that swjdp_transaction_endcheck() is a bit iffy.

Rename DAP_IR_* as JTAG_DP_* since those symbols are specifically
for JTAG-DP (or SWJ-DP in JTAG mode), and won't work with SWD.
Define the JTAG ABORT and IDCODE instructions for completeness;
add a comment about where to (someday) use ABORT.
Fix messaging which assumes everything is an SWJ-DP; say "JTAG-DP"
instead, it's at least more appropriate for all JTAG transports.

Fix: don't print the BASE address except if it's a MEM-AP;
that's an unlikely error, but there's no point getting it wrong.
Tweaks: comments, capitalization.

Make some private functions "static". Remove their public declarations,
and what is now an obviously unused function. Shrinks this object's size
(about 5% on x86_64) while making the code's scope easier to understand.

Instead of magic numbers, use their AP_REG_* constants. Rename
the ROM address symbol as BASE to match ARM's documentation.
Comment various other symbols in the header; add some missing ones.
Remove an unused struct. Add some doxygen for stuff including the
DAP structure and initialization.

Changes from the flat namespace to heirarchical one. Instead of writing:
#include "time_support.h"
the following form should be used.
#include <helper/time_support.h>
The exception is from .c files in the same directory.
Make the "dap info" output more comprehensible:
- Don't show CIDs unless they're incorrect (only four bits matter)
- For CoreSight parts, interpret the part type
- Interpret the part number
- Show all five PID bytes together
- Other minor cleanups
Also some whitespace fixes, and shrink a few overlong source lines.

Move the dap command handler implementations to arm_adi_v5.c,
leaving just thin wrappers in armv7m.c. There should be no
change in functionality here. (From Magnus.)
Minor style cleanup: whitespace, line length, etc. Update spec
references to use docs which are currently available. (From Dave.)
