This helper eliminates significant amount of redundant code in command handler functions throughout the system. It wraps the lower-level parse_* macros to implement a policy for reporting parse errors to the active command context (cmd_ctx). If errors do occur, this macro causes the calling function to abort with the proper return code.

Highlight that the "-expected-id" probably comes from vendor documentation, and that it *should* be used where possible. Don't use ircapture/irmask in examples, to help discourage use of those params when they're not required. Explain a bit better about why/when those params get used. Signed-off-by:

Fail watchpoint_add() if it's the same address but the parameters are different ... don't just assume having the same address means the same watchpoint! (Note that overlapping watchpoints aren't detected...) Handle unrecognized return codes more sanely; don't exit()! And describe command params right. Signed-off-by:

Expose most DWT registers via Tcl; there are a few more, but those are mostly for profiling along with the ITM. Having this set available enables operations which aren't possible with just the standard watchpoint operations. The cycle counter may be interesting. Turn it on after reset by setting the LSB of the dwt_ctrl register, and it counts CPU clocks. You can program the comparator 0 watchpoint to trigger on a given cycle count, rather than a data address. Likewise, comparator 1 may be able to match data values given address matches from one or two other comparators. (Not all hardware supports this capability though; try it. That is something the standard watchpoint methods should eventually handle, for the single address case.) Minor cleanup: remove needless functional indirection for exposing the v7m architctural registers. Signed-off-by:

There's no reason to read which interrupts are enabled from the NVIC; that state isn't used. Plus, it's highly dynamic since firmware can change it at any time; remove the support for those state records. Remove duplicate definition of DWT_CTRL address; shrink a line. Signed-off-by:

Fix the watchpoint error checks, and do them in add(), not later in set() when it's mostly too late. Support the full range of watchpoint sizes (1 to 32K bytes each), and check alignments. Minor cleanup of DWT access: shrink lines, use "+" for address calculations, comment a few issues. Add debug message reporting DWT capabilities, matching the message for FBP, and some minor code and spec review comments. Signed-off-by:

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. Signed-off-by:

We currently do something unusual: version codes in config.in get updated after the release, which means that "git describe" won't match up to development version labels. Comment that trouble spot. We can fix this by switching away from the major/minor/micro type release numbering, as various other projects have done. The major numbers basically don't tend to change, and doing a good job with micro versions is so annoying that they rarely change either.

Contrast releases to git snapshot tarballs. Mention that releases have some quality-improvement focus, with special non-"dev" version IDs. Explain more about version IDs, using "openocd -v" to see them, etc; Make release milestone info be less specific about timing, and presume we have both a merge window and an RC stage. Rework the release process information to match reality a bit more closely. Reference the version.sh script (in one place the wrong script was referenced). Bugfix branches get special treatment, while non-bugfix releases are more or less what *defines* being the mainline branch. Signed-off-by:

The "source" command isn't accepted by ASH; easy to fix. Failures with "-e" are harder to fix. Remove the "-e" (for now) and force bash, for safety. Un-obfuscate the release steps, by using names instead of numbers. Comment the version-number manipulation. Signed-off-by:
