2014-01-20Retire jtag_add_dr_outAndreas Fritiofson
The out only version of jtag_add_dr_scan smells like a bogus optimization that complicates the minidriver API for questionable gain. The function was only used by four old ARM targets. Rewrite the callers to use the generic function and remove all implementations.

2010-06-07jtag: rename JTAG_MOVESTATE to JTAG_TLR_RESETØyvind Harboe
JTAG_MOVESTATE is misleading, this cmd is only used for reset. JTAG_PATHMOVE should be used otherwise. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
2010-03-08jtag: simplify jtag_add_plain_ir/dr_scanØyvind Harboe
These fn's now clearly just clock out/in bits. No mystical fields are involved. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
2010-03-08jtag: jtag_add_ir_scan() now takes a single fieldØyvind Harboe
In the code a single field was all that was ever used. Makes jtag_add_ir_scan() simpler and leaves more complicated stuff to jtag_add_plain_ir_scan(). Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
2010-03-08jtag: retire tap fieldØyvind Harboe
jtag_add_dr/ir_scan() now takes the tap as the first argument, rather than for each of the fields passed in. The code never exercised the path where there was more than one tap being scanned, who knows if it even worked. This simplifies the implementation and reduces clutter in the calling code. use jtag_add_ir/dr_plain_scan() for more fancy situations. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
2010-03-01jtag: the post TAP state is now passed to the driversØyvind Harboe
after clocking out a tms sequence, then the TAP will be in some state. This state is now handed to the drivers. TAP_INVALID is a possible state after a TMS sequence if switching to SWD. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
2010-02-27interface: define TMS sequence commandDavid Brownell
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>
2010-01-05buildfix with -DNDEBUGDavid Brownell
Don't save that state unless its only user, an assertion, is compiled. Saving it broke a cygwin build. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
2009-12-08minidriver: fix inline capability of minidriverØyvind Harboe
Low latency low CPU processing power systems(embedded) will benefit greatly from being able to inline certain jtag_add_xxx() fn's. The trick is that this has to be done in such a way as to allow implementing an OpenOCD API with a shared library(eventually) on a PC hosted OpenOCD.

2009-12-03change #include "minidriver.h" to <jtag/minidriver.h>Zachary T Welch
Changes from the flat namespace to heirarchical one. Instead of writing: #include "minidriver.h" the following form should be used. #include <jtag/minidriver.h> The exception is from .c files in the same directory.

2009-12-02move jtag drivers to src/jtag/driversZachary T Welch
Moves JTAG interface drivers to src/jtag/drivers/, Adds src/jtag/drivers/Makefile.am. Builds libocdjtagdrivers.la. Flattens the rlink driver files into the drivers/ directory, adding the 'rlink_' prefix or '.rlink' suffix as appropriate.
