This patch fixes a segfault when TDO was not received in XXR command:
- allocate space for the value and mask anyway
- clear the mask to zero to effectively skip the output comparison step

Add svf_get_mask_u32 to generate a mask according to bitlen.
Fix this bug in other functions except for svf_check_tdo.

Update the "Reset Configuration" information in the User's guide:
- Convert to @deffn syntax
- Move tutorial text from command descriptions into new sections
- Describe several different types of JTAG-visible reset
- Expand descriptions of configuration tweaks for SRST and TRST
- Link to the "reset" command, and vice versa
- Bugfix the "reset_config" description (it didn't match the code)
Plus, be more proscriptive: do it in board config files, except for
the oddball cases where that won't work. (Current target.cfg files
seem to have much goofage there; several seem board-specific.)

Doc (mostly) update for jtag_khz:
- switch to @deffn syntax
- add entry for "jtag_rclk"
- move deprecated "jtag_speed" into collection of deprecated calls
And for ft2232, don't be the only adapter to *log* an error if RTCK
is requested; it's already reported properly, like any other nonfatal
command parameter. "jtag_rclk" just works as expected, without any
scarey messages.

Make startup for the various server ports be quiet, unless
debugging is active: don't emit needless scarey messages.
Update the relevant documentation and its references:
- For these port commands ... cover the default values;
convert to @deffn syntax; include their use outside of
the configuration stage; and alphabetize.
Similar updates to the rest of that small chapter:
- Highlight that there even *IS* a configuration stage, after
which some command functionality is no longer available.
- For GDB commands ... convert to @deffn syntax; alphabetize;
include a missing command (!); add missing helptext (!) for
one non-missing command; update relevant cross-references
and index entries.

The "Illegal mode for command" diagnostic is deeply useless.
Say "Command '%s' only runs during configuration stage" instead,
letting users know what the real issue is.

Fix a bug that joined us at the last minute, when an efficient
alloca() call got swapped out for a more portable malloc().
Also log one error, to give a clue in case it appears "in the wild".

This was forgotten here. All other LPC targets use
this option.

When the CPU is in the WFI state, the JTAG interface simply doesn't
respond at all and initial tap examination simply fails. Let's simply
do it again when we come around to assert nSRST.

Update two oddball NAND commands to work with {offset, length}
instead of block numbers, matching the other commands as well
as usage in U-Boot and the Linux-MTD utilities.
Document them accordingly. Update the single in-tree use of
those commands (sheevaplug).
ALSO:
(a) Document the current 2 GByte/chip ceiling for NAND chipsize.
(32 bit offset/length values can't represent 4 GBytes.) Maybe
after the upcoming release, the code can switch to 64-bits.
(b) The "nand check_bad_blocks" should report "bad" blocks. They
are not "invalid" blocks; they're "bad" ones.
(c) Tweak the "nand info" command to handle the "no arguments"
case sanely (show everything, instead of showing garbage) and
not listing the blocksize in hex kbytes (duh).

NAND support for DaVinci-family drivers, with HW ECC support.
Declare the NAND chip on the DM355 EVM board.
Currently tested on DM355 for Linux interop using the standard
large page (2KB) chip in the EVM socket; "hwecc1" and "hwecc4"
work fine. (Using hwecc4 relies on patches that haven't quite
made it through the Linux-MTD bottlenecks yet.)
Not yet tested: 1-bit on small-page (although it's hard to see
how that could fail); 4-bit on small page (picky layout issues);
the "hwecc_infix" mode (primarily for older boot ROMs; testing
there is blocked on having new bootloader code).

- Fix minor issues with xrefs not liking parentheses around them.
- Change 'Building' section to 'Building OpenOCD'. It reads better.

- move Doxyfile to Doxyfile.in: type 'make Doxyfile' to recreate it
- create Doxyfile from Doxyfile.in with make rule:
- use sed substitution of $(srcdir) to location directories
- delete all doxygen created files with 'make distclean'
- include all required files (including logger.pl) in distribution

Changes svf_check_tdo function (checks tdo output matches desired values):
- call buf_cmp_mask function to do comparison instead of using a loop.
- fixes a bug when data length is equal to sizeof(int).

- 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.

the key command_*() helper functions, fixng the bugs that turned up.
Several of these bugs were from misuse of PRIi64; that's for 64-bit
integers, NOT for "long long" or "u64" (which work best with %lld).

-jtag.c, interface_jtag_add_dr_out():
- use pointer 'field' instead of scan->fields[field_count]
- restructure the main loop to clearly separate the two cases: TAP is not bypassed / TAP is bypassed
(this is to keep the function similar to interface_jtag_add_dr_scan())
- fix bug where only the first output field has its tap field set
- add asserts to verify that target_tap points to the one not bypassed TAP

-jtag.c, interface_jtag_add_dr_scan():
- use pointer 'field' instead of scan->fields[field_count]
- restructure the main loop to clearly separate the two cases: TAP is not bypassed / TAP is bypassed

- add an assert that checks that no superfluous input fields were passed
