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).
Eliminate redundant check that gets covered by using unsigned type.
Created to eliminate noise from subsequent patches, but this kind of
conversion will be beneficial in similar ways throughout the tree.
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).
Add the 'nand verify' command to perform a dump and fake-write
simultaneously, checking the read bits against those generated by the
write process. Appropriate user documentation for this command has
been added to the user guide as well.
The algorithm presently makes a relatively naive comparison. Some chips
that use ECC may not verify correctly using this implementation, but the
new documentation provides details about this limitation.
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.
This patch eliminates duplicated code in the the NAND 'dump' and 'write'
by using the new static helper functions.
These changes also fix a possible memory leak in nand dump command, in
the case that the dump file failed to open.
Overall, the changes should be functionally equivalent, but the
resulting code will be easier to improve and extend further.
This patch provides helpers APIs that will eliminate duplicated code in
the the NAND 'dump' and 'write' commands by factoring their common code
into static helper functions. These helpers may be useful for creating
new commands, as shown in the final patch to 'verify' flash from a file.
Several previously unreported error conditions now generate messages and
propogate the return codes, such as when the file fails to open and bad
arguments are given. These changes will fix a possible memory leak in
nand dump command, in the case that the dump file failed to open.
Overall, the changes should be functionally equivalent, but the
resulting code will be easier to improve and extend consistently.
Rewrite buf_cmp to use memcpy for bulk of comparison. Add static
helper to perform comparison of trailing byte, which uses another

Previously this flag was stored in "target_type", so that for example
if there were two ARM7TDMI targets in a scan chain, both would claim
to have been examined although only the first one actually had its
examine() method called.
Move this state to where it should have been in the first place, and
hide a method that didn't need exposure ... the flag is write-once.
Provide some doxygen. The examine() method is confusing, since it
isn't separating one-time setup from the after-each-reset stuff. And
the ARM7/ARM9 version is, somewhat undesirably, not leaving the debug
state alone after reset ... probably more of an issue for trace setup

The hello module provides the 'hello' command, printing a greetings
to the command console. It can grow to serve as pedagogical example
of services that OpenOCD developers should use: a runnable style guide.
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.
By using CALL_COMMAND_HANDLER, parameters can be reordered, added, or
even removed in inherited signatures, without requiring revisiting
all of the various call sites.
The FLASH_BANK_COMMAND_HANDLER provides an extended command handler
using the __COMMAND_HANDLER macro, whereby changing that macro is
sufficient to update flash handlers with the new signature. It also
enforces uniform style and scope when implementing this handler.
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.
The "remove (forward) declarations" patch goofed indentation on the
"cortexa8_target" struct; fix.

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.
Add 'const' keyword to 'char *' parameters to allow command handlers to
pass constant string arguments. These changes allow the 'args' command
handler to be changed to 'const' in a subsequent patch.
Subsequent patches expect all command handlers to use a uniform
parameter naming scheme. In the entire tree, these two files used
standard 'argv' instead of our non-standard 'args'. This patch opts
to reduces the noise required to unify the command handlers, using
dominant 'args' form.
A future patch may be used to convert us back to the standard argv, but
that requires coordination with all developers to minimize disruptions.
Separates various groups of files to be built in logical succession.
In each layer, the core module (target.c, nand.c, etc.) is built _after_
their helper modules (e.g. image.c, nand_ecc.c) but _before_ any of
their drivers (e.g. arm966e.c, mx3_nand.c).
This allows problems introduced at the bottom of the stack to result
in build failures as soon as possible, as the helpers and core should
wrap portions of them.

- Saner error return paths
- Simplify arm7_9 init ... no need for extra zeroing!

This patch introduced a bug preventing flash writes from working
on Cortex-M3 targets like the STM32. Moreover, it's the wrong
approach for handling no-MMU targets.
The right way to handle no-MMU targets is to provide accessors
for physical addresses, and use them everywhere; and any code
which tries to work with virtual-to-physical mappings should use
a identity mapping (which can be defaulted).
And ... we can tell if a target has an MMU by seeing if it's
got an mmu() method. No such methood means no MMU.

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.

Provide a cleaner way to handle single inheritance of targets
in C, using the same model Linux does: structs containing other
structs, un-nested via calls to a "container_of()" macro that
are packaged in typesafe inline functions.
Targets already use this containment idiom, but make it much
more complicated because they un-nest using embedded "void *"
pointers ... in chains of up to five per target, which is all
pure needless complication. (Example: arm92x core, arm9tdmi,
arm7_9, armv4_5 ... on top of the base "target" class.)
Applying this scheme consistently simplifies things, and gets
rid of many error-prone untyped pointers. It won't change any
part of the type model though -- it just simplifies things.
(And facilitates more cleanup later on.)
Rule of thumb: where there's an X->arch_info void* pointer,
access to that pointer can and should be removed. It may be
convenient to set up pointers to some of the embedded structs;
and shrink their current "*_common" names (annoyingly long).
