bf96df255e jtag/drivers/ftdi: require defining SWD_EN signal for SWD mode
Use a special signal instead of a dedicated swd mask. Amend
jtag-lock-pick_tiny_2 config accordingly.

64d02ccf82 jtag/drivers/ftdi: declare standard JTAG signals on SWD init
Unfortunately, this means they're available for config files only
after selecting swd transport.

335bafbb25 Auto-select JTAG transport when appropriate
I looked through all the target configs after stripping comments and
such from them with sed to see what jtag-specific commands can appear
first, and it looks like all the meaningful combinations should be
covered.

12e9f6292b Relax polling check if not in JTAG mode
Polling was disabled based on global variables jtag_trst and jtag_srst
which were never touched in non-JTAG mode. Modify the check and remove
the ugly workaround to avoid calls to a possibly uninitialized JTAG
subsystem.

cdd8928a56 Add FTDI SWD driver
This is usable on most or all FTDI adapters using a small hardware tweak.

TCK goes to SWCLK as expected. TDO should be wired to SWDIO. For TDI there
are two options:

Either add a 74HC126 or similar tri-state buffer between TDI and SWDIO,
with OE controlled by a signal named SWDIO_OE. Or simply connect TDI and
SWDIO together via a suitable resistor (220-470 ohms or so depending on
the drive capability of the target and adapter).

nSRST (and of course Vcc, GND) may be connected too but all other signals
should be NC.

ccf4d6d648 cortex_m: Do additional initialization during reset
SAM4L requires additional steps to be taken right after SYSRESETREQ is
issued in order to function robustly:

       - CMSIS-DAP DAP driver needs to explicitly check for sticky bit
         errors since it is possible for adapter to perform successful
         write opration, report no errors and then, under the hood, do
         some other things that will result in sticky bit being set.

       - Debugger needs to wait for security system to finish
         intialization and assert CDBGPWRUPACK before proceeding

This change is related to commit http://openocd.zylin.com/#/c/1995/

0e95ec4070 adi_v5_swd: Separate sticky error clearing from AP abort
Swd_queue_ap_abort should set DAPABORT, not only clear sticky errors.
However, DAPABORT should not be set as soon as there is a single
FAULT/WAIT response. It's an "emergency only" operations for use only when
the AP have stalled the transfer for a long time. So these need to be
separate functions.

Otherwise it breaks SWD targets. The check seems really weird anyway since
it loops through *all* TAPs after the ADIv5 target but doesn't do anything

returning ERROR_OK.

Remove a bogus initialization that was needed because of the odd
behaviour of this routine when an IDCODE wasn't found.
