General rule, this is all board-specific and doesn't belong
in target config files. Some of these were just cosmetic.

It's been about a year since these were deprecated and, in most
cases, removed. There's no point in carrying that documentation,
or backwards compatibility for "jtag_device" and "jtag_speed",
around forever. (Or a few remnants of obsolete code...)
Removed a few obsolete uses of "jtag_speed":
- The Calao stuff hasn't worked since July 2008. (Those Atmel
targets need to work with a 32KHz core clock after reset until
board-specific init-reset code sets up the PLL and enables a
faster JTAg clock.)
- Parport speed controls don't actually work (tops out at about
1 MHz on typical HW).
- In general, speed controls need to live in board.cfg files (or
sometimes target.cfg files), not interface.cfg ...

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so than the PXA255 itself, this is obsolete.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.
