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...

Config for Intel's "Lubbock" PXA255 development board. Even more
so than the PXA255 itself, this is obsolete. AFAIK this was the
first generally available development platform for PXA255. Intel
stopped providing these after other devel boards became available.
One interesting thing about this board from the OpenOCD perspective
is probably its flash configuration. Each bank is 32 bits wide,
built from two 16-bit StrataFlash chips wired in parallel. This
doubles throughput ... it reads/writes 32 bits in the time a single
chip takes to write just 16 bits.
This conf mostly works, given XScale bugfixes, but has some issues
(notably: no access to the on-board SDRAM) flagged by FIXMEs.

This is the very basic board config for the balloon3 board cpu JTAG
channel.
The rest of the config comprises another 14 .cfg files which I suspect
openocd doesn't really want all of. I'm still not sure how to deal
with this. I'll post another mail/patch to discuss.

This is clearly noted in the hardware spec (section 5.2.3); it
works around a chip erratum: "If the MPU_RESET signal is used,
it may cause the EMIFS bus to lock."
I seem to have a board with such an initial build. The chip
is labeled XOMAP. Presumably, parts without that "X" prefix
(eXperimental) resolve this.

Update the board config for the DaVinci DM355 EVM so the reset-init
event handler does the rest of the work it should do:
- minor PLL setup bugfixes
- initialize the DDR2 controller
- probe both NAND banks
- initialize UART0
- enable the icache

defining ntrst_delay is pointless; don't.
At least the LM3S3748 eval board doesn't need nsrst_delay
either; remove that too.

Prepare the DaVinci PLL code to support the version 0x0E module
used in newer chips (e.g. dm365): rename the original code so
it's specific to version 0x02 PLL modules, and update the dm355evm
code to use that new name.
Fix two minor bugs in that version 2 code: sysclk3 setup used
the sysclk2 divider address (affecting video processing on dm355,
no worry for now) and sysclk2 setup had a syntax error.
Also minor fixups to dm355evm, mostly to permit use of RTCK.

This patch adds support for the Luminary Micro LM3S9B90 target and
LM3S9B92 Evaluation Kit. These kits include a new ft2232 adapter, the
Luminary In-Circuit Debug Interface (ICDI) Board, so this is added as a
new ft2232 layout called "luminary_icdi".

Improve the PXA255 target config: move all that board-specific
setup to the pxa255_sst board.cfg, to which it evidently belongs
(it's the only PXA255 board now included).
Provide the PXA255 JTAG id from Intel docs, and add a comment
about how this chip is now EOL'd (last orders taken).
Note that I still can't get my old PXA255 board to work. There's
something broken in the reset sequence, which is preventing the
TAP from coming up at all. Old mailing list posts suggest this
is a longstanding bug...
