gdb_server: fake step if thread is not current rtos thread
gdb assumes that a rtos can make any thread active at will in response
to a 'Hg' packet. It further assumes that it needs to step-over after
setting a breakpoint on frame #0 of any non-current thread. Both
assumptions are not valid for an actual rtos. We fake the step-over to
not trigger an internal error in gdb. See
https://sourceware.org/bugzilla/show_bug.cgi?id=22925 for details.
gdb_server: fix ignored interrupt request from gdb during stepping
Normally, when a ctrl-c is received from gdb, a SIGINT is reported back
unconditionally to tell gdb that the target has stopped in response.
However when a rtos support was configured, the rtos awareness overwrote
the signal with an actual thread state, which gdb then ignored and got
stuck without the user able to interrupt.

target: use correct target in target-prefixed commands and event handlers
This change contains an alternative to Matthias Welwarsky's #4130
(target-prefixed commands) and to #4293 (event handlers).
get_current_target() must retrieve the target associated to the current
command. If no target associated, the current target of the command
context is used as a fallback.
Many Tcl event handlers work with the current target as if it were
the target issuing the event.
current_target in command_context is a number and has to be converted
to a pointer in every get_current_target() call.
The solution:
- Replace current_target in command_context by a target pointer
- Add another target pointer current_target_override
- get_current_target() returns current_target_override if set, otherwise
current_target
- Save, set and restore current_target_override to the current prefix
in run_command()
- Save, set and restore current_target_override to the event invoking
target in target_handle_event()

rtos: run rtos create hook only once on autodetect

function was called. Make sure this happens only once and only
if rtos autodetection is used.
The RTOS handlers present OS threads to gdb but the openocd

This patch allows closing this gap inside the RTOS handler.
The default implementation just returns the current core, but
a RTOS handler can provide its own function that associates a

cortex_a: fix handling of Thumb-2 32bit breakpoints
When debugging Thumb-2 code, Gdb will at times send a

the instruction to break on is 32 bits long. Handle this by
replacing it with two consecutive 16bit Thumb BKPTs and make
sure to save and restore the full, original 32bit
instruction.
Note that this fix is only applicable if you debug a bare-metal program
(like the linux kernel) with the 'wrong' gdb, e.g. use an
"arm-linux" gdb instead of an "arm-eabi" gdb. But since most people
may not know about the subtle differences between gdb configurations
regarding thumb2 breakpoints it's still valid.
The ICEPick-D jtag router has core control registers
that provide the same (or similar) functionality as
the tap control register, for individual cores
accessible through the same tap (e.g. through a DAP).
Core control registers are located at address "0x60 +
core-id" of the ROUTER address space (IR=ROUTER).
It is sometimes helpful or even necessary to modify the
core control register. This patch renames the
"icepick_d_coreid" function to the more appropriate
"icepick_d_core_control" and adds a "value" argument
that allows writing of arbitrary value.
"icepick_d_tapenable" is extended by an optional value

flash Kinetis: make FCF protection more user friendly
The Flash Configuration Field on Kinetis devices requires protection
because it is located in program flash space (at 0x400) and writing
an improper data to it may permanently lock the device. Even an erased
flash sector containing FCF engages security lock (not permanent one)
on the next reset or power cycle.
'kinetis fcf_source protection' mode was introduced in the change #3562.
Flash driver in this mode sets FCF immediately after sector erase to
prevent unintentional security lock. To do so the driver needs to know
FCF values before flash image data is actually processed. Flash
protection bits are available in bank structure, FOPT can be set by
'kinetis fopt' command and securing device by FSEC is not supported.
Nevertheless an inexperienced user flashed the device using an image
with FCF values different from those set in OpenOCD config and
concluded programming did not work as some verify errors showed.
This change tries to write maximum possible from image data
retaining FCF protection.
Check FCF in programmed data and report if some field differs from
values set by OpenOCD flash block protection and 'kinetis fopt' command.
Warn user about verify errors caused by FCF protection.
On devices with ECC flash (K26, K66 and KV5x) it is impossible to change
already programmed FCF - it would result in an ECC error. As FCF was
written just after erase in 'kinetis fcf_source protection' mode
the warning issued during flash write is the only possible action.
On non-ECC flash devices use cumulative flash programming to
set FCF values requested in programmed image data.
Use FSEC from programmed data only if it does not request a secure
mode. Device can be secured only in 'kinetis fcf_source write' mode.
Use FOPT from programmed data if its value was not configured
in OpenOCD config by 'kinetis fopt' command.

jtagspi: new protocol that includes transfer length
This commit contains a rewrite of the jtagspi protocol and covers both
changes in the jtagspi.c openocd driver and the bscan_spi
(xilinx_bscan_spi) proxy bitstreams. The changes are as follows:
1. Always perform IR scan to ensure proper clearing of BYPASSed DRs.
2. Insert alignment cycles for all BYPASSed TAPs:
The previous logic was erroneous. The delay in clock cyles from a bit
written to the jtag interface to a bit read by the jtag interface is:
* The number of BYPASSed TAPs before this (jtagspi) tap
* The length of the jtagspi data register (1)
* The number of BYPASSed TAPs before this one.
I.e. it is just the number of enabled TAPs. This also gets rid of the
configuration parameter DR_LENGTH.
3. Use marker bit to start spi transfer
If there are TAPs ahead of this one on the JTAG chain, and we are in
DR-SHIFT, there will be old bits toggled through first before the first
valid bit destined for the flash.
This delays the begin of the JTAGSPI transaction until the first high bit.
4. New jtagspi protocol
A JTAGSPI transfer now consists of:
* an arbitrary number of 0 bits (from BYPASS registers in front of the
JTAG2SPI DR)
* a marker bit (1) indicating the start of the JTAG2SPI transaction
* 32 bits (big endian) describing the length of the SPI transaction
* a number of SPI clock cycles (corresponding to 3.) with CS_N asserted
* an arbitrary number of cycles (to shift MISO/TDO data through
subsequent BYPASS registers)
5. xilinx_bscan_spi: clean up, add ultrascale
This is tested on the following configurations:
* KC705: XC7K325T
* Sayma AMC: XCKU040
