Tomas Vanek 390c9aca1f tcl at91samdXX.cfg: partially revert change 3722
Commit 25d7ba19c9 introduced a problem
with 'reset halt' due to setting srst_pulls_trst:

Error: cortex_m.c:595 cortex_m_halt(): can't request a halt while
  in reset if nSRST pulls nTRST

Sorry, I don't know why I overlooked it when I tested #3722.

Tomas Vanek 25d7ba19c9 tcl at91samdXX.cfg: update config to current OpenOCD status
Remove comment about workaround of not working 'reset halt' - not needed
as 'reset halt' is working as expected @ EDBG with srst_only.
Add srst_pulls_trst to reset_config as it no more triggers an error.

Andreas Färber 0c8ec7c826 Fix spelling of ARM Cortex
It's Cortex-Xn, not Cortex Xn or cortex xn or cortex-xn or CORTEX-Xn
or CortexXn. Further it's Cortex-M0+, not M0plus.

Cf. http://www.arm.com/products/processors/index.php

Consistently write it the official way, so that it stops propagating.
Originally spotted in the documentation, it mainly affects code comments
but also Atmel SAM3/SAM4/SAMV, NiietCM4 and SiM3x flash driver output.

Found via:

  git grep -i "Cortex "
  git grep -i "Cortex-" | grep -v "Cortex-" | grep -v ".cpu"
  git grep -i "CortexM"

Tomas Vanek 751e2454bf at91samd: handle reset run/halt in DSU
Atmel introduced a "Device Service Unit" (DSU) that holds the CPU
in reset if TCK is low when srst (RESET_N) is deasserted.
Function is similar to SMAP in ATSAM4L, see http://openocd.zylin.com/2604

Atmel's EDBG adapter handles DSU reset correctly without this change.

An ordinary SWD adapter leaves TCK in its default state, low.
So without this change any use of sysresetreq or srst
locks the chip in reset state until power is cycled.

A new function dsu_reset_deassert is called as reset-deassert-post event handler.
It optionally prepares reset vector catch and DSU reset is released then.

Additionally SWD clock comment is fixed in at91samdXX.cfg and clock is
lowered a bit to ensure a margin for RC oscillator frequency deviation.
adapter_nsrst_delay 100 is commented out because is no more necessary after

Paul Fertser c7384117c6 Allow transports to override the selected target (hla configs unification)
This should allow to share common configs for both regular access and
high-level adapters.

Use the newly-added functionality in stlink and icdi drivers, amend
the configs accordingly.

Runtime-tested with a TI tm4c123g board.

Andrey Yurovsky 215c41c017 add support for Atmel SAMD NOR Flash
This adds a new NOR Flash driver, "at91samd", which supports the
built-in Flash on Atmel's D-series Cortex M MCUs, starting with the D20.
Parts and their geometry are detected automatically using the DSU and
lookup schemes described in the D20 document, 42129F–SAM–10/2013.
Future D-series variants and families should presumably use this
controller as well (possibly with minor changes and improvements).

Tested on the SAMD20 Xplained Pro board, for which we also add the
corresponding Flash configuration.

Spencer Oliver 67f664a068 cfg: add initial Atmel xplained kit support
These kits feature a CMSIS-DAP compliant debugger and so have been added
as part of the pending support.

Currently the flash drivers for the L8 and D20 are wip.

One issue this implementation of CMSIS-DAP raised is that it supports
512byte HID reports, however using the current HIDAPI we have no cross platform
way of querying this info. Long term we plan to add this support to HIDAPI.
