Rewrite arm11_handle_bool to provide a generic on/off command helper.
Refactors COMMAND_PARSE_BOOL to use new command_parse_bool helper,
which gets reused by the new command_parse_bool_any helper.
This later helper is called by the new command helper function to
accepts any on/off, enable/disable, true/false, yes/no, or 0/1 parameter.
Adds several macros similar to COMMAND_PARSE_NUMBER, but for parsing
boolean command arguments. Two flavors are provided to provide
drop-in compatibility with existing code, allow for the elimination
of a lot of code bloat while improving the error checking and reporting.
COMMAND_PARSE_ON_OFF parses "on"/"off" command parameters.
COMMAND_PARSE_ENABLE parses "enable"/"disable" command parameters.
Both print the error and return an error out of the calling function.
Moves definitions for each layer into their own file, eliminating
layering violations in the built-in TCL code. Updates src/Makefile.am
rules to include all files in the final startup.tcl input file, and
others Makefile.am rules to distribute the new files in our packages.
Adds the command_invocation structure to encapsulate parameters for
all COMMAND_HANDLER routines. Rather than passing several arguments
to each successive subroutine, a single pointer may be passed around.
Changes the CMD_* macros to reference the new fields.
Updates run_command to create an instance and pass it to the handler.
Add additional macros to allow command handling to be migrated easily:
CMD_CTX, CMD_ARGC, and CMD_ARGV. Updates CMD_NAME to use CMD_ARGV.
In addition to making the remaining patches of this series cleaner,
this introduces easily sed-able symbols that could allow us to retire
these once the command handler infrastructure matures (i.e. pre-1.0).
Rename the "armv4_5" command prefix to straight "arm" so it makes
more sense for newer cores. Add a simple compatibility script.
Make sure all the commands give the same "not an ARM" diagnostic
message (and fail properly) when called against non-ARM targets.

Use size_t instead of uint32_t when specifying file sizes. Update all
consumers up through the layers to use size_t when required. These
changes should be safe, but the higher-levels will need to be updated
further to receive the intended benefits (i.e. large file support).
Add error checking for fileio_read and file_write. Previously, all
errors were being silently ignored, so this change might cause some
problems for some people in some cases. However, it gives us the chance
to handle any errors that do occur at higher-levels, rather than burying
our heads in the sand.
Uses unsigned type to pass line numbers.
Use uint64_t to pass sleep routines their milliseconds. Updates sleep
routines to use this type and improve whitespace.
The "improve inline binarybuffer helpers" mis-handled bytes
with the high bit set; treat them as unsigned, not signed.

The ARRAY_SIZE macro was defined in several target files, so move it
to types.h.
This patch also removes two other identical macros: DIM (from jtag.h)
and asizeof (from arm11.h).
The container_of macro is useful as a general solution. It belongs
in types.h, rather than target.h where it was introduced. Requires
the offsetof macro, which comes from <stddef.h> (moved as well).
In some cases, the FILEIO_NONE access mode may be useful as a parameter
to indicate that file access should be disabled. High-level routines can
use it to skip file access calls, as 'fileio_open' will fail presently
if called to open a file using this mode.
Rewrite buf_cmp to use memcpy for bulk of comparison. Add static
helper to perform comparison of trailing byte, which uses another
static helper to perform a maksed comparison. The masked comparison
helper is used by the buf_cmp_mask to simplify its loop.
Improve types to use void *, unsigned, and return bool.
Lots of files still include it, often through needless
duplicate inclusion of "log.h"; sigh.
This cleans up the inclusion graph a bunch, so there are
fewer inclusion paths, but it doesn't change much otherwise.

Purge an unused routine from the tree and remove a layering violation.
If this code is needed, it should reappear somwhere in src/jtag/,
where struct scan_field gets defined.
The number of command arguments will always be 0 or more, so use
the right type in handlers. This has a cascading effect up through
the layers, but the new COMMAND_HANDLER macros prevented total chaos.
This patch adds new typedefs for command handler callback functions.
Users of this type signature were updated to use these new types.
It uses the new __COMMAND_HANDLER macro to prevent duplication.
The COMMAND_HANDLER and COMMAND_HELPER macros allow commands to be
defined in a manner that decouples them from the exact order and type of
their parameters. Once converted, incremental changes to the command
handler type can be addressed in incremental patches that do not need to
touch the entire tree.
These macros' implementation, __COMMAND_HANDLER, is used to define the
new command_handler_t type, and additional patches will use it to derive
new macros to define extended command types (e.g. flash, nand, pld).
The CALL_COMMAND_HANDLER provides a means of calling helpers or nested
handlers from withing a command handler.
This patch uses C99 varadic macro expansion. Please report compilers
that cannot handle this code.
Eliminate duplicate code for linking commands into a list.
Adds a check to ensure the command does not already exist;
if it does, return that one instead of creating a duplicate.
Add help for commands regardless of whether a handler is involved.
With this, all sorts of new commands can be found in 'help' text.
Hopefully, all of them have been documented....
Sadly, the lsort function appears to handle nested lists poorly, such
that sub-commands do not group with their parents.
The command_name function returns a malloced string for a given
command and its parents. This can be used to display a message
to the user, but it is used internally to handle registration
and syntax errors. This helps permit arbitrary command nesting.
The "$ocd_HOSTOS" variable was wrongly documented. Fix its
documentation, and its value on Linux.
Shrink a few of the too-long lines.

This patch changes the duration_* API in several ways. First, it
updates the API to use better names. Second, string formatting has
been removed from the API (with its associated malloc). Finally, a
new function added to convert the time into seconds, which can be
used (or formatted) by the caller. This eliminates hidden calls to
malloc that require associated calls to free().
This patch also removes the useless extern keyword from prototypes,
and it eliminates the duration_t typedef (use 'struct duration').
These API also allows proper error checking, as it is possible for
gettimeofday to fail in certain circumstances.
The consumers have all been chased to use this new API as well, as
there were relatively few cases doing this type of measurement.
In most cases, the code performs additional checks for errors, but
the calling code looks much cleaner in every case.
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.
Compilation on cygwin, using gcc v3 with option -mno-cygwin,
currently produces a large number of the following warnings:
warning: `gnu_printf' is an unrecognized format function type
These have been introduced with the recent MinGW GNU C99 printf
compliance patch, as gnu_printf was only introduced with gcc v4.4
and is not recognized with earlier versions.
The attached fix adds gcc version detection to the previous patch
to avoid the problem.
Passing "--std=gun99" is unfortunately not sufficient to make current
MinGW compilers conform with respect to checking printf format strings.
(The C runtime seems not to have problems.)
Fix by using a "gnu_printf" format specifier not "printf".
Use JIM_WIDE_MODIFIER for the sscanf format, and apply it for MINGW32 as
well as other Windows environments. (Microsoft doesn't conform to the
C99 standard, and uses "%I64d" not "%lld" for "long long".)
NB: __MINGW32__ should work on both w32 and w64,.
Generate a C struct with the data, and use that, instead of an
assembly language file. The assembly language causes issues on
Darwin and MS-Windows, which don't necessarily use GNU AS; or
if they do, don't necessarily use its ELF syntax.
It's also better in two other ways: fewer global symbols; and
the init-time size check gets optimized away at compile time.
(Unless it fails, in which case bigger chunks of the file vanish.)

This makes the documentation a closer match to "help" output:
- "pathmove" somehow was not documented in the User's Guide
- "jtag_nsrst_assert_width" and "jtag_ntrst_assert_width"
are new; both needed descriptions.
- Removed two undocumented and fairly useless script mechanisms:
* production/production_info/production_test ... using it,
requires replacing everything; so having it adds no value.
* cpu ... way out of date; hopeless to keep that current
Note that anyone using that "production" stuff already defines
their own procedures, and can keep using them with no change.

This abstracts the "jtag arp_init-reset" call into a method
called from OpenOCD startup and reset processing.
Platforms which have different requirements for how such hard
resets must be performed can now override "init_reset" instead
of needing to rebuild custom hacked versions of the server.

Currently the "debug_level 3" command tracing ignores commands
