20a077eadb jtag/adi_v5_jtag: fix infinite recursion in jtagdp_transaction_endcheck()
Calling ahbap_debugport_init() is wrong here because the actions
performed by it might lead to jtagdp_transaction_endcheck errors thus
leading to infinite recursion.

The removed code is not needed now because target polling should lead
to reexamination automatically, and both cortex_a and cortex_m call
ahbap_debugport_init() as part of their target examine handler.

This was reported as a real life issue on IRC by Weaselweb with
Cortex-A target. Quitte reports similar results in some circumstances
(adapter_khz too high) with LPC17xx.

677b02b475 adi_v5: Remove unused features of the DAP and SWD interfaces
These features are not currently used so remove or disable them before
something starts to. Not having them around simplifies redesign of the
APIs.

13f6c889ab Remove unnecessary (void *)
When pointer casts are needed, cast directly to the correct type, instead
of going via void*.

Don't explicitly cast to void* if it would have been done implicitly.

2a8a89edcb arm_adi_v5: fix mem_ap_read_buf_u32() JTAG nastiness..
Moved JTAG code out of transport-neutral file (arm_adi_v5.c) into
transport specific file (adi_v5_jtag.c).
Added ap_block_read to dap_ops interface (arm_adi_v5.h) to support
the move.

fa93174a56 arm_adi_v5: add/move apsel member in struct adiv5_dap
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 05ab8bdb81 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).

cb0de21d0c jtagdp: remove #if 0'd kludges and explain why the code is correct
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

fc9de56a25 ADI_v5 - it's not always an "SWJ-DP"
So don't use the name "swjdp" for all DAPs; rename to
plain old "dap", which *is* always correct.

36df240cea jtag: cut down on usage of unintended modification of global end state
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.

6f8b8593d6 ADIv5 transport support moves to separate files
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.
