- Add jtag_execute_queue in jtag_add_reset after interface_jtag_add_reset.
- Use tap_set_state to demark TAP_RESET, instead of cmd_queue_cur_state
- cmd_queue_cur_state needs to be retired.

Updates to the J-Link interface driver to support more device versions:
- Add capability detection:
- if capable, detect protocol version; otherwise, assume v2 protocol.
- if capable, detect buffer size; otherwise, assume minimal.
- Disable command result queries for devices using v2 protocol.
- Defined and use JTAG2 command with v2 protocol; JTAG3 is v3 protocol.
- Add TCL command to allow explicit setting of J-Link protocol version.
With approval, I revised the patch to make the following changes:
- add static keywords to new jlink-specific variables
- factor calculation of major_version to be more readable
- remove braces around simple one-line statements in if/else clauses
- remove (rather than #if 0) duplicate reset code; it is in SVN
- use &function to be clearer when passing function pointers
- add symbols for EMU_CMD_GET_CAPS bits; do not hard-code constants!
- almost renamed jlink_handle_jlink_hw_jtag_command (seriously?!?!)
- rewrote that function using a switch statement.
- made version request processing easier to understand and modify
- improve alternate endpoint detection:
- make code easier to read by using temporary variables
- eliminate extra level of indentation and redundant logging
- use ternary conditional to select JTAG2 or JTAG3 command
- reverse version test in jlink_usb_message to reduce indentation
- this had the biggest effect in cleaning up this patch
- use C99's ability to declare new/changed variables with less scope
- add spaces around binary operators in new/changed code
- revert other superfluous whitespace/comment style changes

Remove un-implemented and dubious "nand copy" command.
Doing this efficiently would mean doing the copying on
the target CPU, instead of back and forth through JTAG.
If anyone ever needs this functionality, that's what
they should implement.
Also, update on-line "help" for "nand dump" to display
its two optional flags; and for "nand write" to display
a recently added flag.

Improve support for the DM355 EVM board, and eventually other boards based
on DaVinci chips:
- Provide generic "davinci.cfg" to hold utilities that can be reused by
different chips in this family. Start with PINMUX, PSC, and PLL setup.
- DM355 chip support updates: provide a dictionary with chip-specific
symbols, load those utilities.
- Create a new dm355evm board file, with a reset-init event handler
which uses those utilities to set up PLLs and clocks, configure the
pins, and improve the JTAG speed limit.
Also a minor tweak: provide a virtual address for the work area, matching
what the very latest kernels do. It's probably unwise to use OpenOCD while
the MMU is active though.
The DRAM isn't yet accessible, but NAND access is mostly ready.

Add a "NAND Commands" section to to the TEXI docs, covering the basic
commands except for those previously discussed as being due for removal
("nand copy") or switching to use byte offsets not block numbers.
This uses the "@deffn..." syntax for defining commands, as somewhat
suggested by the TEXI documentation, and adds a new "Command Index".
We might prefer to merge those indexes for the near term, but I think
the "@deffn" approch is probably worth switching to.
Updates a few other bits to clarify that "flash" doesn't just mean NOR.
And to fix one niggling falsity: the "reset-init" event *is* used, and
in fact it's quite important.
