Globally rename "jtag_khz" as "adapter_khz", and move it out of the "jtag"
command group ... it needs to be used with non-JTAG transports
Includes a migration aid (in jtag/startup.tcl) so that old user scripts
won't break. That aid should Sunset in about a year. (We may want to
update it to include a nag message too.)

Streamline use of the layout: have the "ft2232_layout" command
look it up and save the result, instead of having a few different
chunks of code looking it up later, and saving just its name (which
is already part of the layout). This
- is cleaner
- reports errors sooner
- facilitates earlier adapter-specific setup
- removes unused "default to "usbjtag" logic

This patch greatly simplifies the Versaloon driver:
- reducing the code size from more than 50K to less than 28K
- adding support for IR/DR scan with unlimited size
- using tap_get_tms_path and tap_get_tms_path_len.

We'll need to be able to work with debug adapter interfaces (drivers)
even when they're not used for JTAG ... for example, while there are
multi-transport drivers which support JTAG *and* several other
transports (or just one more, like SWD) there are also adapters
with more limited goals (and no JTAG support at all).
Start decoupling the two concepts ("debug adapter driver", "jtag")
by having two command groups, which initialize separately.
This will help us support OpenOCD sessions using only non-JTAG
transports, in which JTAG commands should not be registered.
Update docs to mention that the JTAG, SVF, and XSVF commands
won't work without a JTAG transport.
Note that at least commands working with SRST are still inappropriately
coupled to JTAG ... inappropriate because (a) SRST is not part of the
JTAG standard, for all that many platforms (like ARM) expect it; and also
(b) because they're used with non-JTAG debug and programming interfaces,
too. They should perhaps become generic "interface" operations at some
point. (Similarly with the clock rate to be used by a given adapter.)

At the end I have added comments /* FIXME: to be removed */
There are 3 lines in which my simplification is not complete due to
data dependency with LOG_DEBUG() messages visible in the patch.
Such log_debug has been introduced on Jan 22, 2007 with commit
4fc97d3f2726efa147cfdb0c456eace51550e1e3 during development activity
in this file/procedure.
From my point of view, these logs can be removed, since not part of a
consistent flow of information.
Alternatively, could be borrowed in the new cfi_send_command(), but
this will increase verbosity.

jtag_add_dr/ir_scan() now takes the tap as the first
argument, rather than for each of the fields passed
in.
The code never exercised the path where there was
more than one tap being scanned, who knows if it even
worked.
This simplifies the implementation and reduces clutter
in the calling code.
use jtag_add_ir/dr_plain_scan() for more fancy situations.

Get rid of needless and undesirable code duplication for

This partially corrects an inappropriate name choice (and its
associated FIXME).
There are still too many variables named "swjdp", bug little
current code actually relies on them referencing an SWJ-DP instead
of some other flavor of DAP. Only the two new dap_to{swd,jtag}()
calls could behave differently on an SWJ-DP instead of a SW-DP or
a JTAG-DP.

When the beginning or end of the specified range of sectors
already has the requested protection status, don't ask the
flash driver to change those sectors.
This will among other things turn command sequences like
this into the NOPs one would expect:
flash protect_check 0
flash info 0
... reports everything as unprotected ...
flash protect 0 0 1 off
That speeds things up (by whatever work was just avoided).
Also, with Stellaris (which can't unprotect flash at page level)
this can eliminate some undesirable/false error reports. (And
finishes fixing a bug currently listed in our bug database...)

The NOR infrastructure caches some per-sector state, but
it's not used much ... because the cache is not trustworthy.
This patch addresses one part of that problem, by ensuring
that state cached by NOR drivers gets invalidated once we
resume the target -- since targets may then modify sectors.
Now if we see sector protection or erase status marked as
anything other than "unknown", we should be able to rely
on that as being accurate. (That is ... if we assume the
drivers initialize and update this state correctly.)
Another part of that problem is that the cached state isn't
much used (being unreliable, it would have been unsafe).
Those issues can be addressed in later patches.

Give a more accurate failure message when trying to unprotect; don't
complain about pages being write protected, just say that unprotect is
not supported by the hardware ... referencing the new "recover" command,
which is the way to achieve that.
Likewise, when trying to protect, talk about "pages" (matching hardware
doc) not "sectors" (an concept that's alien to these chips).
Also make the helptext for the "recover" command mention that it
also erases the device.

Make ADIv5 internals use the two new transport-neutral calls for reading
and writing DP registers; and do the same for external callers. Also,
bugfix some of their call sites to handle the fault returns, instead of
ignoring them.
Remove most of the JTAG-specific calls, using their code as the bodies
of the JTAG-specific implementation for the new methods.
NOTE that there's a remaining issue: mem_ap_read_buf_u32() makes calls
which are JTAG-specific. A later patch will need to remove those, so
JTAG-specific operations can be removed from this file, and so that SWD
support will be able to properly drop in as just a transport layer to the
ADIv5 infrastructure. (The way read results are posted may need some more
attention in the transport-neutrality interface.)

To support both JTAG and SWD, ADIv5 needs DAP operations which are
transport-neutral, instead being of JTAG-specific. This patch:
- Defines such a transport-neutral interface, abstracting access
to DP and AP registers through a conceptual queue of operations.
- Builds the first implementation of such a transport with the existing
JTAG-specific code.
In contrast to the current JTAG-only interface, the interface adds
support for two previously-missing (and unused) DAP operations:
- aborting the current AP transaction (untested);
- reading the IDCODE register (tested) ... required for SWD init.
The choice of transports may be fixed at the chip, board, or JTAG/SWD
adapter level. Or if all the relevant hardware supports both transport
options, the choice may be made at runtime, This patch provides basic
infrastructure to support whichever choice is made.
The current "JTAG-only" transport choice policy will necessarily continue
for now, until SWD support becomes available in OpenOCD. Later patches
start phasing out JTAG-specific calls in favor of transport-neutral calls.

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.
