* zy1000: embedded ice dcc tweakØyvind Harboe2010-03-081-21/+48
| | | | | | | | | | How many bits to shift out before/after enabled tap not in bypass is calculated outside the loop. This is more of a demonstration of principle and to clarify code than a performance optimisation as such. Follows up a bit on the simplification work in jtag interface.

* jtag: simplify jtag_add_plain_ir/dr_scanØyvind Harboe2010-03-081-4/+14
| | | | | | | These fn's now clearly just clock out/in bits. No mystical fields are involved. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
* jtag: jtag_add_ir_scan() now takes a single fieldØyvind Harboe2010-03-081-4/+2
| | | | | | | | 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>
* jtag: retire tap fieldØyvind Harboe2010-03-081-53/+19
| | | | | | | | | | | | | | | | | 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>
* zy1000: faster jtag_add_ir_scan()Øyvind Harboe2010-03-011-9/+3

* zy1000: arm11 load is now fasterØyvind Harboe2010-03-011-42/+71

* interface: define TMS sequence commandDavid Brownell2010-02-271-1/+10
| | | | | | | | | | | | | | | | | | | | | | | 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>
* arm11: improve performance using minidriver hookØyvind Harboe2010-02-221-3/+65
| | | | | | | | | | | | | | | | zy1000 performance for GDB load went from 100kBytes/s to 300kBytes/s @ 8 MHz by implementing the inner loop of unack arm11 memory writes directly on top of the hw fifo. Profiling info: 78.57 0.77 0.77 arm11_run_instr_data_to_core_noack_inner 5.10 0.82 0.05 memcpy 4.08 0.86 0.04 jtag_tap_next_enabled 3.06 0.89 0.03 gdb_input Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
* arm11: allow minidrivers to implement inner loop of memory writesØyvind Harboe2010-02-221-0/+8
| | | | | | | | | | | | | | | This allows minidrivers to e.g. hardware accelerate memory writes. Same trick as is used for arm7/9 dcc writes. Added error propagation for memory transfer failures in code rearrangement. Also the JTAG end state is not updated until after the memory write run is complete.

* zy1000: jtag_add_dr_scan() performance improvementØyvind Harboe2010-02-221-8/+15

* zy1000: flush jtag buffer before changing speedØyvind Harboe2010-01-191-0/+3
| | | | | | | | | It is conceivable that there could be commands in the queue when a speed change request comes in. Flush the hw queue before changing speed. Not observed, found by inspection. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
* zy1000: reset bugfixØyvind Harboe2010-01-111-1/+7
| | | | | | | flush JTAG FIFO before reset. Fixes RCLK problems observed w/lpc2148, but really fixes a wider range of problems. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>

* zy1000: keep up with changes to command structureØyvind Harboe2009-11-301-0/+1
| | | | | | | | | | | | | Add missing COMMAND_REGISTRATION_DONE. For now the command syntax for zy1000 needs to be compatible across 0.3/0.4, the world outside OpenOCD interfaces to zy1000 using the old syntax. Post 0.4 release(0.4.1 even) I'll switch to subcommand scheme. Switch to subcommands post 0.3 lifecycle. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
