dsp563xx: rudimentary gdb support
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.

arm_adi_v5: add/move apsel member in struct adiv5_dap
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 05ab8bdb813acdcd74afa71d6656c2df816cb230 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).

lpc32xx: Flash driver
Based on the lpc3180 driver, but released as a separate driver for two reasons:
1) I don't have an lpc3180 to test it against, so it might unintentionally break compatibility.
2) It's using a different OOB layout than lpc3180.
Rewritten so that it no longer borrows code from the NXP CDL library. Instead borrowing code from the u-boot port to lpc32xx, written by Kevin Wells.
Tested on lpc3250 (Hitex LPC3250-Stick). OOB layout is compatible with LPCLinux.

cortex_a9: move dap_ap_select to arm_avi_v5
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

cortex_a9: implement read/write memory through APB-AP
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)

Add '-coreid' target option to support multiple cores per TAP.
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.
fix segfault from stack corruption in ahbap_debugport_init
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.

I took the stm32x NOR flash driver and adapted it for the Ember EM357

Add another level of procedures to LPC2xxx initialization - procedures for specific targets (setup_lpc<number>) take core clock and adapter clock as parameters. This way "constant" parameters (flash size and type, CPUTAPID, etc.) do not need to be copied if one wishes to change the "variable" parameters - like the core clock or adapter clock - in a board config file or somewhere else.
