Arguments for "flash bank" command are already
parsed and put in "bank" struct.
Removed code to parse them again.

Syntax of "flash bank" command requires:
- chip_width as CMD_ARGV[3]
- bus_width as CMD_ARGV[4]
Actual code swaps the arguments.
Bug has no run time impact since wrong variables
are only used to check value and both are checked
against same constraint.

jtag_get/set_end_state() is now deprecated.
There were lots of places in the code where the end state was
unintentionally modified.
The big Q is whether there were any places where the intention
was to modify the end state. 0.5 is a long way off, so we'll
get a fair amount of testing.

Until this time only basic SLC functionality exists when you want to use SLC to access external nand flash.
Basic functionality can be selected with command:
lpc3180 select 0 slc
It is anyway very slow to write/read to/from nand flash.
With the new command, SLC speed improved about 20 times, and hardware ECC info also read/written from/to nand flash OOB area:
lpc3180 select 0 slc bulk
Speed improvement achieved by using working are in SRAM of the LPC3250 chip and controlling DMA controller to interact between SRAM and SLC peripheral.
Here are the patches, and if they are ok than take them.
Tested with hitex LPC3250 usb stick.

Fixes bug that prevented users from specifying a base address of
0x80000000 or higher in image commands (flash write_image, etm image,
xscale trace_image).
image.base_address is an offset from the start address contained in
the image file (if there is one), or from 0 (for binary files). As a
signed 32-bit int, it couldn't be greater than 0x7fffffff, which is a
problem when trying to write a binary file to flash above that
address. Changing it to a 64-bit long long keeps it as a signed
offset, but allows it to cover the entire 32-bit address space.

Add flash algorithm support for the PIC32MX.
Still a few things todo but this dramatically decreases
the programing time, eg. approx programming for 2.5k test file.
- without fastload: 60secs
- with fastload: 45secs
- with fastload and algorithm: 2secs.
Add new devices to supported list.

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.

In the code a single field was all that was ever used. Makes

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.

JEDEC standard reports Vpp integer part encoded as 4 bit HEX value.
To print it using decimal digits, %u is required.
Other voltage values are coded as BCD, so %x is appropriate.
Code already prints one nibble at a time, so no need for field width
and precision in format string.

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.

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.

Stellaris chips have a procedure for restoring the chip to
what's effectively the "as-manufactured" state, with all the
non-volatile memory erased. That includes all flash memory,
plus things like the flash protection bits and various control
words which can for example disable debugger access. clearly,
this can be useful during development.
Luminary/TI provides an MS-Windows utility to perform this
procedure along with its Stellaris developer kits. Now OpenOCD
users will no longer need to use that MS-Windows utility.

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
