* arm_adi_v5: add/move apsel member in struct adiv5_dapLuca Ellero2011-02-171-1/+1
| | | | | | | | | | | | | | | This patch tries to make some order in "apsel" mess. "dap apsel" command was quite useless (and broken) by itself. With this patch we can use it to select between AHB or APB memory access (previous patch 05ab8bdb813acdcd74afa71d6656c2df816cb230 was somehow broken). - moves member apsel (in struct adiv5_dap) to ap_current - adds apsel member this strange choice is made trying to keep coherence in "dap apsel" command and to keep compatibility with other code (for example cortex_a8).

* 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>

* 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: 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.
