Provide new helper proc that can set up either an SWD or JTAG DAP
based on the transport which is in use -- mostly for SWJ-DP.
Also update some SWJ-DP based chips/targets to use it. The goal
is making SWD-vs-JTAG transparent in most places. SWJ-DP based chips
really need this flexible configuration to cope with debug adapters
that support different transports, without needing new target configs
for each transport or adapter.
For JTAG-DP, callers will use "jtag newtap" directly, as today; only
one chip-level transport option exists.
For SW-DP (e.g. LPC1[13]xx or EFM32, they'll use "swd newdap" directly
(part of an upcoming SWD transport patch). Again, only one transport
option exists, so hard-wiring is appropriate there.

Fix some issues with the generic LPC1768 config file:
- Handle the post-reset clock config: 4 MHz internal RC, no PLL.
This affects flash and JTAG clocking.
- Remove JTAG adapter config; they don't all support trst_and_srst
- Remove the rest of the bogus "reset-init" event handler.
- Allow explicit CCLK configuration, instead of assuming 12 MHz;
some boards will use 100 Mhz (or the post-reset 4 MHz).
- Simplify: rely on defaults for endianness and IR-Capture value
- Update some comments too
Build on those fixes to make a trivial config for the IAR LPC1768
kickstart board (by Olimex) start working.
Also, add doxygen to the lpc2000 flash driver, primarily to note a
configuration problem with driver: it wrongly assumes the core clock
rate never changes. Configs that are safe for updating flash after
"reset halt" will thus often be unsafe later ... e.g. for LPC1768,
after switching to use PLL0 at 100 MHz.

It has an integrated bootloader and can boot from a variety of sources:
external SPI or I2C non-volatile memory, an image loaded over UART1,

Use the correct name for these TAPs, which we can recognize since
their IDs were assigned by ARM and these chips all document the
presence of an ETB. The 0x2b900f0f is ETB11; the 0x1b900f0f

The semantics of "-work-area-virt 0" (or phys) changed with
the patch to require specifying physical or virtrual work
area addresses. Specifying zero was previously a NOP. Now
it means that address zero is valid.
This patch addresses three related issues:
- MMU-less processors should never specify work-area-virt;
remove those specifications. Such processors include
ARM7TDMI, Cortex-M3, and ARM966.
- MMU-equipped processors *can* specify work-area-virt...
but zero won't be appropriate, except in mischievous
contexts (which hide null pointer exceptions).
Remove those specs from those processors too. If any of
those mappings is valid, someone will need to submit a
patch adding it ... along with a comment saying what OS
provides the mapping, and in which context. Example,
say "works with Linux 2.6.30+, in kernel mode". (Note
that ARM Linux doesn't map kernel memory to zero ...)
- Clarify docs on that "-virt" and other work area stuff.
Seems to me work-area-virt is quite problematic; not every
operating system provides such static mappings; if they do,
they're not in every MMU context...

Gets rid of the runtime warning "stm32.bs: nonstandard IR mask"

This gets rid of runtime warnings from the use of numbers.
STM32 and LPC2103 were tested. Other LPC updates are the
same, and so are safe. The CFI updates match other tested
changes now in the tree.

Now I can issue "reset halt" and have everything act smoothly;
the vector_catch hardware is obviously not kicking in, but the
rest of the reset sequence acts sanely.
- TAP "setup" event enables the DAP, not omap3_dbginit
(resolving a chicken/egg bug I noted a while back)
- Remove stuff from omap3_dbginit which should never be
used in event handlers
- Cope better with slow clocking during reset
Also, stop hard-wiring the target name: use the input params in
the standard way, and set up $_TARGETNAME as an output param.

Startup now mostly works, except that the initial target state
is "unknown" ... previously, it refused to even start.
Getting that far required fixing the ircapture value (which
can never have been correct!) and the default JTAG clock rate,
then providing custom reset script.
The "reset" command is still iffy. DCSR updates, and loading
the debug handler, report numerous DR/IR capture failures.
But once that's done, "poll" reports that the CPU is halted
(which it shouldn't be, this was "reset run"!), due to the
rather curious reason "target-not-halted".
Summary: you still can't debug these parts, but it's closer.

Without some extra delay after releasing SRST, we seemed to
be trying to talk to the TAP before it was ready to respond.

The model is that this fires after scanchain verification, when it's
safe to call "jtag tapenable $TAPNAME". So it will fire as part of
non-error paths of "init" and "reset" command processing. However it
will *NOT* trigger during "jtag_reset" processing, which skips all
scan chain verification, or after verification errors.
ALSO:
- switch DaVinci chips to use this new mechanism
- log TAP activation/deactivation, since their IDCODEs aren't verified
- unify "enum jtag_event" scripted event notifications
- remove duplicative JTAG_TAP_EVENT_POST_RESET

It can be sped up later, once it's known the PLLs are active.
Note that modern tools from TI all use adaptive clocking; and
that if that's done with OpenOCD, "too fast" is also a non-issue.
