Really a Cortex-A specific option, but there is no
system in place to support target specific options
currently and there has been no need for such a system
until now.

The patch below fixes step <address> on mips_m4k.
Spencer Oliver <spen@spen-soft.co.uk>:
The current code is used on all other arch's - is
there a underlying issue with those aswell ?
I don't think dsp563xx_once_read_register() would ever
be called with len==0, but it would have been broken in
that case.

Problem is, trying to print "Hello, world!\n" just prints endless H's, because r1 is never incremented.
One way to fix it would be to add a "++" after "r1".
Fix a bunch of typos.
Most are in code comments, so nothing should break. UNKOWN_COMMAND and
CMD_UNKOWN are not used elsewhere, so correcting the spelling should
also not break anything.
This patch add rudimentary gdb support. The gdb register list
order is corrected. All registers are now 32bit width. Events are
send to signalize gdb the current target status. Resume and step
function was corrected to consider a modified pc register. Read/write
memory now support L memory type, this means a memory with alternating
y/x memory words. The memspace variable, used by gdb, is now observed
before a default memory access is initiated. Dummy functions for breakpoint
and watchpoint are added.
This patch tries to make some order in "apsel" mess.
"dap apsel" command was quite useless (and broken) by itself.
With this patch we can use it to select between AHB or APB memory access
(previous patch 05ab8bdb81 was somehow broken).
- moves member apsel (in struct adiv5_dap) to ap_current
- adds apsel member
this strange choice is made trying to keep coherence in "dap apsel" command
and to keep compatibility with other code (for example cortex_a8).

This patch move the dsp563xx_target_create function to the
related code block. Also the target examine function was added
and the register cache is initialized in a separate function. The
missing functionality to invalidate the x memory context on memory
writes was also added.
This patch change the return value on a jtag communication error
to TARGET_UNKNOWN because this function should return the current
target status and not a error code from the underlying api call.
Also the validity of the jtag_status is extended to all static
bits in this value.
I've been working on Rodrigo on adding support to flash
Freescale dsp56800e devices and have been looking at the
dsp563xx code. I think the define for the JTAG CLAMP
instruction in dsp563xx_once.c is incorrect. It should
be 0x05 according the Freescale AN2074 (and is also
0x05 in the dsp568xx according to AN1935). It won't
actually change anything in OpenOCD since this define
is not used anywhere (as far as I can tell).
dap_ap_select was used in the code at various points, but that can lead to
confusion, without any knowledge of what AP is really selected at some
points.
Some bugs derive from this (for example md/mw doesn't work well after
issueing "dap apsel" command).
Moving it to arm_adi_v5.c (using mem_ap_sel* functions instead of mem_ap_*)
make the code more clear and more easier to maintain.
In the future it should be made "static" to avoid its use outside arm_adi_v5
One further benefit is the various goto has been removed as well

This patch adds read/write capability to memory addresses not
accessible through AHB-AP (for example "boot ROM code").
To select AHB or APB, a "dap apsel" command must be issued:
dap apsel 0 -> following memory accesses are through AHB
dap apsel 1 -> following memory accesses are through APB
NOTE: at the moment APB memory accesses are very slow, compared
to AHB accesses. Work has to be done to get it faster (for
example LDR/STR instead od LDRB/STRB)

Save, select and restore AP in cortex_a9_step and cortex_a9_init_debug_access.
Fixes a bug where the wrong AP is selected after a reset.

Hello,
this patch add commands to access to x,y and p memory. For run time optimization some local jtag
function was changed to static inline.

Hello,
this patch adds the missing cpu registers and the correct read/write register functions and fixed
most of the halt/step/resume issues. The complete missing error propagation was added.
+ fix tab/spaces

If a handler for the reset-assert event it present, skip the usual reset
handling. This is needed, for example, for board-level resets.

ARM Cortex-A9 multi-core chips expose a single TAP/DAP which connects
to both cores. The '-coreid' option selects which core the target
should connect to.
Note that at present, OpenOCD can connect to either core, but not both
simulatenously, until ADI contexts can be shared.

ahbap_debugport_init was queueing reads to a local stack variable but
didn't execute the queue before returning. Since the result of the reads
are not used anyway, it's better to pass NULL as the destination instead of
a dummy variable. I changed this throughout the function, even for the
reads that were actually executed.

Remove extra \n from LOG_DEBUG, LOG_INFO, and LOG_WARNING messages
Remove LOG_INFO_N
LOG_INFO_N was only used once and had a \n at the end
Change LOG_USER_N calls that end with \n to LOG_USER
Add a working area that is preserved between calls to
mips_m4k_bulk_write_memory - this gives us a speed increase
of approx 3kb/sec during flash writes to the pic32mx.
This area is released during a resume/reset.

We only use the struct working_area member 'free' as a
true/false type so might as well use a bool data type.
