Without some extra delay after releasing SRST, we seemed to
be trying to talk to the TAP before it was ready to respond.

The model is that this fires after scanchain verification, when it's
safe to call "jtag tapenable $TAPNAME". So it will fire as part of
non-error paths of "init" and "reset" command processing. However it
will *NOT* trigger during "jtag_reset" processing, which skips all
scan chain verification, or after verification errors.
ALSO:
- switch DaVinci chips to use this new mechanism
- log TAP activation/deactivation, since their IDCODEs aren't verified
- unify "enum jtag_event" scripted event notifications
- remove duplicative JTAG_TAP_EVENT_POST_RESET

It can be sped up later, once it's known the PLLs are active.
Note that modern tools from TI all use adaptive clocking; and
that if that's done with OpenOCD, "too fast" is also a non-issue.

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
git-svn-id: svn://svn.berlios.de/openocd/trunk@2699 b42882b7-edfa-0310-969c-e2dbd0fdcd60
- remove endianness options; these chips hard-wire "little"
- $_TARGETNAME updates:
* don't pass $_TARGETNAME where a TAP label is required
* flash config uses $_TARGETNAME (it might not be target #0)
* simplify one $_TARGETNAME construction
- update work area setup:
* remove VM spec; these chips have no VM!
* fix some wrong sizes (0x4000 == 16K, not 4K)
* simplify: take defaults
- comment fixups

Add flash programming support for NXP LPC1700 cortex_m3 based family

on ARM9 cores, and update the DaVinci config files so they
no longer explicitly specify it.

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".

Minor bugfix ... previous version was tested *with* ICEpick active.
The "-disable" can swap with "-enable"; but not with an empty string.

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...

an improved DM355, integrating much better HD video support,
Ethernet, and other goodies.

Update the Beagle setup:
- OMAP3530 updates:
* split ICEpick TAP enable support to its own file, for
reuse and eventually for storing other utility code
like emulation reset
* clean up, including labeling the tap as for DAP not
for the Cortex-A8 and making endianness non-variable
* add a few FIXMEs
- BeagleBoard cleanup: there's no SRST, "endstate" is gone, etc
I'm not sure I'd say it's further than "barely limping" just yet.
Key issues remain lack of Cortex-A8 support, and more complete
support for resetting.

DM6446 config updates:
- List two more TAPs, as disabled, mostly for doc purposes
- Included basic ICEpick support, still disabled by default
- Shorten line lengths
- Use $_TARGETNAME to configure the ETM and ETB
- This ARM core don't support endianness overriding
For now, boards that can't jumper EMU0/EMU1 will need to tweak
a variable's setting.

Add another board ... OMAP2420 "H4" board. This won't be very widely
used with OpenOCD, but with mainline support in both U-Boot and Linux
it at least makes for a more complete set (and another testcase).
This is incomplete support in several respects. The ARM11 support is
not very deep yet; most registers aren't available, and the ETM can't
be hooked up. Plus, there's no script for OMAP-specific stuff like
setting up the SDRAM controller. Eventually the same NAND controller
driver should work with OMAP2 and OMAP3.

Add configuration for an old AT91rm9200 board, the Cogent CSB 337.
Worth noting from the OpenOCD perspective:
- It got a real hardware trace port connector; wired up here as
much as we can, lacking inexpensive trace-aware dongles.
- This is the first in-tree use of the "arm920t cp15" command.
It adjusts the CPU clocking and enables i-cache, which gives
more than 4x speedup after booting Linux; it's visible even
just running U-Boot.

Split out OSK5912 board support from the omap5912 target config, and make
it pass sanity checks on my (Rev C/original) hardware:
- Fix syntax error ("-irlen" not "irlen")
- Provide real TAP ids for the ARM926ejs and the C55x dsp
- Label both CPUs appropriately (DSP, ARM)
- List both flash chips
The scan chain looks like this (note truncated DSP instruction code):
TapName | Enabled | IdCode Expected IrLen IrCap IrMask Instr
---|--------------------|---------|------------|------------|------|------|------|---------
0 | omap5912.dsp | Y | 0x03df1d81 | 0x03df1d81 | 0x26 | 0x00 | 0x00 | 0xffffffff
1 | omap5912.arm | Y | 0x0692602f | 0x0692602f | 0x04 | 0x01 | 0x00 | 0x0c
2 | omap5912.unknown | Y | 0x00000000 | 0x00000000 | 0x08 | 0x00 | 0x00 | 0xff
I still don't know what that third TAP is; maybe an early version of
an ICEpick JTAG router.
