* interface: define TMS sequence commandDavid Brownell2010-02-271-0/+18
| | | | | | | | | | | | | | | | | | | | | | | For support of SWD we need to be able to clock out special bit sequences over TMS or SWDIO. Create this as a generic operation, not yet called by anything, which is split as usual into: - upper level abstraction ... here, jtag_add_tms_seq(); - midlayer implementation logic hooking that to the lowlevel code; - lowlevel minidriver operation ... here, interface_add_tms_seq(); - message type for request queue, here JTAG_TMS. This is done slightly differently than other operations: there's a flag saying whether the interface driver supports this request. (In fact a flag *word* so upper layers can learn about other capabilities too ... for example, supporting SWD operations.) That approach (flag) lets this method *eventually* be used to eliminate pathmove() and statemove() support from most adapter drivers, by moving all that logic into the mid-layer and increasing uniformity between the various drivers. (Which will in turn reduce subtle bugginess.) Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* change #include "jtag.h" to <jtag/jtag.h>Zachary T Welch2009-12-031-1/+1
| | | | | | | | | | | | Changes from the flat namespace to heirarchical one. Instead of writing: #include "jtag.h" the following form should be used. #include <jtag/jtag.h> The exception is from .c files in the same directory.
* remove register_callbacks from jtag interfaceZachary T Welch2009-11-241-3/+1
| | | | | | | | Changes the jtag_interface->register_callbacks field to a list of commands to be registered. Changes callback to invocation of register_commands() with that command registration list. Removes all JTAG interface driver register_command callback functions, which the previous commits had converted into identical calls.
* command_context_t -> struct command_contextZachary T Welch2009-11-131-1/+1
| | | | Remove misleading typedef and redundant suffix from struct command_context.
* jtag_interface_t -> struct jtag_interfaceZachary T Welch2009-11-131-3/+2
| | | | Remove useless typedef and redundant suffix from struct jtag_interface.
* SVF: clean up, mostly for TAP state name handlingDavid Brownell2009-10-231-3/+0
| | | | | | | | | | | | | | | | | | | | | - Use the name mappings all the other code uses: + name-to-state ... needed to add one special case + state-to-name - Improve various diagnostics: + don't complain about a "valid" state when the issue is actually that it must be "stable" + say which command was affected - Misc: + make more private data and code be static + use public DIM() not private dimof() + shorten the affected lines Re the mappings, this means we're more generous in inputs we accept, since case won't matter. Also our output diagnostics will be a smidgeon more informative, saying "RUN/IDLE" not just "IDLE" (emphasizing that there can be side effects).
