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.

The SRST configuration options are not specific to JTAG, so this
command may be needed with non-JTAG debug sessions. Just move
the command to a different group.
(The TRST options are, however, clearly JTAG-specific, but for
compatibility, they're now left alone. The flags they control
could later be disabled in non-JTAG sessions.)

Globally rename "jtag_nsrst_assert_width" as "adapter_nsrst_assert_width",
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.

The default config script will now dynamically setup the BMX registers
in the reset init script.
This will also work if the user overrides the default working area.

These routines apply to non-JTAG debug adapters too. To
reduce confusion, give them better (non-misleading) names.

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

Simple patch that fixes the broken xscale icache and dcache commands.
This broke when the helper functions and macros were changed.

Remove undesirable
- backslashes at end-of-line;
- initializations of BSS data to zero/NULL;
- overlong lines (80+ characters)
- whitespace issues
- brackets around single-line statements

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.)

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.
