For STR7x flash, the device cannot be queried for the protect status.
The solution is to remove the protection on reset init. The driver
also initialises the sector protect field to unprotected.

The default state of the STR7 flash after a reset init is unlocked.
The information in the flash driver now reflects this.
The information about the lock status cannot be read from the
flash chip, so the user is informed that flash info might not
contain accurate information.

Remove more remnants of the old "jtag_device" syntax.
Don't [format "%s.cpu" $_CHIPNAME] ... it's needless complexity.
Remove various non-supported "-variant" target options; they're not
needed often at all.
Flag some of the board files as needing to have and use target files
for the TAP and target declarations.

Behave like OMAP3530: force global software reset. Given the
patch to teach ARM11 how to use these events, and use VCR to
catch the reset vector, this works better than either the
current reset logic or than using SRST.

Rename the "armv4_5" command prefix to straight "arm" so it makes
more sense for newer cores. Add a simple compatibility script.
Make sure all the commands give the same "not an ARM" diagnostic
message (and fail properly) when called against non-ARM targets.

Kick in ETM (and ETB) support for ARM11. Tested on OMAP 2420,
so update that configuration. (That's an ARM1136ejs, ETB,
OpenGL ES1.1, C55x DSP, etc.)
Also update the other ARM11 ETM + ETB targets in the tree
to set up these modules. (Not tested.)

Various cores with an ETB have its TAP misnamed ... either as a
boundary scan TAP or as the iMX "Secure JTAG Controller" (which
is, among other things, a JRC that could be used to shorten
scan chains).
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
is an older module, just called "ETB".
Also shrink the ETB's IR configuration; the default IR-Capture
value is fine, and the mask can specify that all four bits are
safe to check (per ARM documentation).

Here's a patch for the double-reset problem on STM32. I've tested
downloading and debugging with GDB and Eclipse, and everything seems
to work fine.
This effectively sets reset_config to none. trst_only would also
be ok, but that's better left to a board configuration file since
not all boards wire it up.
The NVIC is used to trigger reset, which at least on this chip also
pulses nSRST so the whole system does get rest -- exactly once.

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...

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.
