Andreas Fritiofson says "If any adapter driver does not work with
arbitrary lengths of individual fields, it's a bug."
https://sourceforge.net/p/openocd/mailman/message/35091945/
Note also that lengths of at least 96 bits are already in use, eg. in
mips_ejtag_add_scan_96().

Just like observed with the General App Kit earlier, it now started to

SWD IDCODE 0x2ba01477
TARGET: xmc4500.cpu - Not halted
in procedure 'reset'
in procedure 'ocd_bouncer'
SWD IDCODE 0x2ba01477
Halt timed out, wake up GDB.
Rely on the target's default sysresetreq behavior to allow flashing to

When using SWD rather than JTAG transport, the lpcspifi driver complains:
Error: Device ID 0x0 is not known as SPIFI capable
Error: auto_probe failed
This is because target's JTAG tap->idcode is zero for SWD.
Drop this check completely and hardcode the addresses for now. Neither
the JTAG TAPID nor the SWD IDCODE are unique enough to detect the exact
chip model and thereby its memory map.

The capability to lock the debug interface on EFM32
controllers was lacking in OpenOCD.
After receiving some pointers by zapb_ and PaulFertser
on IRC (thanks guys!) I have added this capability.
This works by writing the required bits in the debug
lock word to '0'.
Note: there is currently no way to re-enable the debug
interface from OpenOCD as doing this requires specific
pin wiggling that is currently not implemented yet.
However: having the capability to lock the debug interface
is useful when building a volume programming jig.
You can flash the program code, verify and then
lock the debug interface so that the device cannot
be read when it is deployed in the field.

Before this change jim_target_reset() checked examined state of a target
and failed without calling .assert_reset in particular target layer
(and without comprehensible warning to user).
Cortex-M target (which refuses access to DP under active SRST):
If connection is lost then reset process fails before asserting SRST
and connection with MCU is not restored.
This resulted in:
1) A lot of Cortex-M MCUs required use of reset button or cycling power
after firmware blocked SWD access somehow (sleep, misconfigured clock etc).
If firmware blocks SWD access early during initialization, a MCU could
become completely inaccessible by SWD.
2) If OpenOCD is (re)started and a MCU is in a broken state unresponsive
to SWD, reset command does not work even if it could help to restore communication.
Hopefully this scenario is not possible under full JTAG.
jim_target_reset() in target.c now does not check examined state
and delegates this task to a particular target. All targets have been checked
and xx_assert_reset() (or xx_deassert_reset()) procedures were changed
to check examined state if needed. Targets except arm11, cortex_a and cortex_m
just fail if target is not examined although it may be possible to use
at least hw reset. Left as TODO for developers familiar with these targets.
cortex_m_assert_reset(): memory access errors are stored
instead of immediate returning them to a higher level.
Errors from less important reads/writes are ignored.
Requested reset always leads to a configured action.
arm11_assert_reset() just asserts hw reset in case of not examined target.
cortex_a_assert_reset() works as usual in case of not examined target.
