* jtagdp: remove #if 0'd kludges and explain why the code is correctØyvind Harboe2010-09-211-16/+24
| | | | | | | | | short story: if the JTAG clock is too high, then the behavior will be flaky and kludging the code may seem to make things beter, but really it's just a red herring. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>

* jtag: do not use jtag_get_error()Øyvind Harboe2010-06-211-5/+2
| | | | | | | normal code should not call jtag_get_error(), but rather check the return code from jtag_execute_queue(). Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>

* jtag: retire jtag_get/set_end_state()Øyvind Harboe2010-03-191-2/+0
| | | | | | | Voila! This get rids of mysteries about what what state the TAP is in. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
* ADI_v5 - it's not always an "SWJ-DP"David Brownell2010-03-181-35/+35
| | | | | | | So don't use the name "swjdp" for all DAPs; rename to plain old "dap", which *is* always correct. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* jtag: retire one instance of jtag_get_end_state() usageØyvind Harboe2010-03-181-4/+3
| | | | | | Less global variables.... Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
* jtag: cut down on usage of unintended modification of global end stateØyvind Harboe2010-03-181-3/+3
| | | | | | | | | | | | | jtag_get/set_end_state() is now deprecated. There were lots of places in the code where the end state was unintentionally modified. The big Q is whether there were any places where the intention was to modify the end state. 0.5 is a long way off, so we'll get a fair amount of testing.

* ADIv5 transport support moves to separate filesDavid Brownell2010-03-161-0/+481
Unclutter arm_adi_v5.c by moving most transport-specific code to a transport-specific files adi_v5_{jtag,swd}.c ... it's not a full cleanup, because of some issues which need to be addressed as part of SWD support (along with implementing the DAP operations on top of SWD transport): - The mess where mem_ap_read_buf_u32() is currently coded to know about JTAG scan chains, and thus needs rewriting before it will work with SWD; - Initialization is still JTAG-specific Also move JTAG_{DP,ACK}_* constants from adi_v5.h to the JTAG file; no other code should care about those values.
