gdb_server: set current_target from connection's one
In a multi-target environment we are supposed to have a single
gdb server for each target (or for each group of targets within
a SMP node).
By default, the gdb attached to a server sends its command to
the target (or to the SMP node targets) linked to that server.
This is working fine for the normal gdb commands, but it is
broken for the native OpenOCD commands executed through gdb
"monitor" command. In the latter case, gdb "monitor" commands
will be executed on the current target of OpenOCD configuration
script (that is either the last target created or the target
specified in a "targets" command).
Fixed in gdb_new_connection() by replacing the current target
in the connection's copy of command context.

gdb_server: only trigger once the event gdb-detach at gdb quit
When GDB quits (e.g. with "quit" command) we first execute
gdb_detach() to reply "OK" then, at GDB disconnect (either TCP

In case GDB is killed or it crashes, OpenOCD only executes the
latter when detects the disconnection.
Both gdb_detach() and gdb_connection_closed() trigger the event
TARGET_EVENT_GDB_DETACH thus getting it triggered twice on clean

Do not trigger the event TARGET_EVENT_GDB_DETACH in gdb_detach()

individually removing targets from the list.

Add gdb_report_register_access_error command
With this option enabled (it's disabled by default) errors accessing
registers are returned to gdb. Otherwise they are ignored and success is
reported to gdb. (This is the current behavior.)
We want this for RISC-V, but there's still some cleanup that needs to be
done before that can be upstreamed.

arm_adi_v5: Add ability to ignore the CSYSPWRUPACK bit
The CTRL/STAT register in the ARM DAP DP has a debug power up
ack bit and a system power up ack bit. Some devices do not set
the system power up ack bit until sometime later. To avoid having
the initial target examination fail due to this or to have a
sticky bit error report claim power failure due to this a user
can now specify that this bit should be ignored.

drivers/kitprog: workaround KitProg firmware bug of missing ZLP
KitProg firmware does not send a zero length packet at the end of the bulk-in
transmission of a length divisible by a bulk packet size. This is inconsistent
with the USB specification and results in jtag_libusb_bulk_read()
waits forever when a transmission of specific size is received.
Limit bulk read size to expected number of bytes for problematic tranfer sizes.
Use 1 second timeout as the last resort.

target/cortex_m: avoid dwt comparator overflow
Avoid ever overflowing the DWT_COMPARATOR array by allocating space for
16 comparators (the field is masked by 0xf).
On a stm32f767zi chip (on a nucleo-767zi board) I've been seeing crashes
with address sanitizer enabled due to its (apparent) 10 present
comparators. This appears to be due to
https://sourceforge.net/p/openocd/tickets/178/.
In non-address sanitizer builds, this would likely cause some random
memory to be written to in some cases. (see above bug for observations).

xilinx-dna.cfg: generic tools for reading Xilinx Device DNA
Most Xilinx FPGA devices contain an embedded, unique device identifier.
The identifier is nonvolatile, permanently programmed into the FPGA, and is
unchangeable providing a great serial / tracking number.
This commit adds generic support for reading the Xilinx Spartan 6 and 7
Series (Kintex, Artix, Ultrascale) Device DNA. The code is similar to
the function in fpga/xilinx-xc6s.cfg for Spartan 6 but the register
addresses are different and the logic has been simplified.
The code was not placed in xilinx-xc7.cfg. The approach of defining taps
in the same file as library code to use them is fundamentally broken on
boards that have more than one FPGA or other chips. This commit (like
the addition of support for Xilinx XADC) starts to remedy that by
splitting library code from board-specific fixed definitions.
The support code is sourced in the Kasli and KC705 board support files
as it was tested on these boards.

Kasli is an open hardware FPGA board. It is part of the Sinara family of

Xilinx Artix 7 100T FPGA, DDR3 RAM, a clock reconstruction and
distribution network, four 6 Gb/s transceiver links (three SFP and
one SATA) as well as interfaces to up to 12 Eurocard Extension Modules

xilinx-xcu: add Xilinx Ultrascale tap data
The Ultrascale series is a bit more complicated to handle since with the
stacked and interconnected dies the IR gets longer. This adds support
for all currently known chips from the Ultrascale family.
- add 'dap create' command to create dap instances
- move all dap subcmmand into the dap instance commands
- keep 'dap info' for convenience
- change all armv7 and armv8 targets to take a dap
instance instead of a jtag chain position
- restructure tap/dap/target relations, jtag tap no
longer references the dap, daps are now independently
created and initialized.
- clean up swd connect
- re-initialize DAP also on JTAG errors (e.g. after reset,
power cycle)
- update documentation
- update target files
Extend the CTI abstraction to be accessible from TCL and
change the 'target' command to accept a cti 'object' instead of a
base address. This also allows accessing CTI instances that are not
related to a configured target.
If we enter debug state from EL0, some registers are not accessible.
Temporarily move to EL1H and back to gain access. Also, fix
armv8_dpm_modeswitch() to not immediately restore the previous state
on elevating the privilege level.
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.
