Angus Gratton f701c0cbeb newdap: Ignore -irlen/-irmask/etc newdap params on SWD or CMSIS-DAP
Previously the -irlen parameter was required even though it is not
a part of the SWD or CMSIS-DAP transports.

This may eventually need to be changed for CMSIS-DAP once that
supports JTAG as well.

Andreas Fritiofson f75345b915 drivers/jlink: Revert old workaround
This workaround broke usage with at least the I.MX6Q.

The comment implies that talking to the J-Link dongle itself should
fail if the target isn't reset, which sounds really strange. I'm
guessing it just triggered another bug in OpenOCD or Segger FW which
might have been fixed since. Revert and wait and see if there are any
failure reports.

Tested with Kwikstik (J-Link + Kinetis K40), not with the mentioned
adapter.

Andreas Fritiofson 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.

Andrey Smirnov 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/

Andreas Fritiofson 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.

Andreas Fritiofson 9ec211de1c adi_v5: Remove strange IDCODE check from dap info handler
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
at all with the result, other than not setting the return values despite
returning ERROR_OK.

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