Remove misleading typedef from struct struct pending_scan_result.
Future patches need to remove these duplicated types and code.
|
|
Remove useless typedef and redundant suffix from struct armjtatew_jtag.
|
|
Remove useless typedef and redundant suffix from jtag_tap_event_action.
|
|
Remove useless typedef and redundant suffix from jtag_event_callback.
Add documentation for the structure.

Remove useless typedef and redundant suffix from struct jtag_interface.
|
|
Removes another useless typedef and suffix.

Remove useless typedef and redundant suffix.
|
|
Move the bitq_state structure from the header to source file, as it
is used internally.
Also removes its silly typedef.
|
|
Remove useless structure typedef.
|
|
Search and destroy the jtag_tap_t typedef. This also cleans up a
layering violation, removing the declaration from types.h.
|
|
Remove useless structure typedef.
|
|
Removes useless and confusing typedef for log callback structure.
Types with _t should be suitable for passing by-value as arguments.
|
|
Somehow I managed to slip a temporary build file into the tree.
Remove it and update the .gitignore file so it doesn't happen again.

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.
|
|
This patch removes 'cmd' from the list of direct parameters, moving
that pointer to args[-1] (by way of the new CMD_NAME macro).
|
|
This patch prevents command handlers from modifying the strings passed
in the 'args' array.
|
|
Prevents the command name from being modified in command handlers.
Again, this has cascading effects, but the patches are fairly minimal.
|
|
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 introducing the CMD_NAME macro, this parameter may be integrated
as args[-1] in command.[ch], without touching any other call sites.
|
|
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.
|
|
Update virtex module to use abstracted PLD command handling.
|
|
Abstracts the extended NAND command handling to allow the function
signature to be controlled by __COMMAND_HANDLER.
|
|
Defines all flash_bank_command handlers using the new macro.
|
|
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.
|
|
Add S3C24XX_DEVICE_COMMAND macros to abstract common command handler
conventions.
|
|
Rewrites the dap_* command helpers to use the COMMAND_HELPER paradigm.
Uses CALL_COMMAND_HELPER to hide inherited calling conventions.
|
|
Define the numerous helpers that inherit command handler parameters
using the COMMAND_HELPER macro.
|
|
|
|
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.

Add a typedef for command output handler function type, simplifying
the appearance of functions that use it and eliminating duplicate code.
|
|
The "remove (forward) declarations" patch goofed indentation on the
"cortexa8_target" struct; fix.

To be more informative (and consistent with flash and pld trees), change
'device' parameter name to 'nand' in NAND source files. This change
eliminates confusing 'device->device->' instance from the code, and
it simplifies the forthcoming command handler patches.

ARM11 and newer cores include updated ETM modules. Recognize
their version codes and some key config differences. Sanity
checked on an OMAP2, with an ETM11RV r0p1 (ETMv3.1).
This still handles only scan chain 6, with at most 128 registers.
Newer cores (mostly, Cortex) will need to use the DAP instead.
Note that the newer ETM modules don't quite fit the quirky config
model of the older ones ... having more port widths is easy, but
the modes aren't the same. That still needs to change.
Fix a curious bug ... how did the register cache NOT get saved??

Add the khz and speed_div functions to the parport interface driver.
Add the parport_toggling_time function that tells the parport driver
how long (in nanoseconds) it takes for the hardware to toggle TCK.

Now that nothing uses the old ETM handle any more, remove it.
Add minimal header tweaks, letting non-ARM7 and non-ARM9 cores
access ETM facilities.
Now ARM11 could support standard ETM (and ETB) access as soon as
it derives from "struct arm" ... its scanchain 6 is used access
the ETM, just like ARM7 and ARM9.
The Cortex parts (both M3 and A8) will need modified access methods
(via ETM init parameters), so they use the DAP. Our first A8 target
(OMAP3) needs that for both ETM and ETB, but the M3 ETM isn't very
useful without SWO trace support (it's painfully stripped down), so
that support won't be worth adding for a while.

Make ETM itself use the new toplevel ETM handle, instead
of the to-be-removed lower level one. As of this patch,
nothing should be using the old ARM7/ARM9-specific handle.

Make both useful ETM port drivers (etb, etm_dummy) use the new
toplevel ETM handle, instead of the to-be-removed lower level one.
Do the same for the "oocd-trace" prototype too; and fix its
error reporting paths: return failure codes, don't exit(), etc

Rename "struct armv4_5_common_s" as "struct arm". It needs
a bit more work to be properly generic, and to move out of
this header, but it's the best start we have on that today.
Add and initialize an optional ETM pointer, since that will
be the first thing that gets generalized.
The intent being: all ARMs should eventually derive from
this "struct arm", so they can reuse the current ETM logic.
(And later, more.) Currently the ARM cores that *don't* so
derive are only ARMv7-M (and thus Cortex-M3) and ARM11.

Without this patch, running "openocd -c 'jtag interface'" segfaults.
Now, it returns the string "undefined" when the interface is unset.
|
|
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.
|
|
Add helpers to manage adding entries to the helptext list.
Adds support for arbitrarily nested commands.
|
|
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.
|
|
Use continuation characters to wrap the help command into 80 columns.
|
|
Documenting command handler parameters is redundant and pointless.
|
|
Removes forward declarations by moving command registration after
defintion of the command handlers.
|
|
|
|
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.
