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.

2010-03-08jtag: jtag_add_ir_scan() now takes a single fieldØyvind Harboe

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>

2010-02-27interface: 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>
