Koudai Iwahori d0436b0cda armv8: Add support of pointer authentication
When pointer authentication is enabled, some upper bits of the link
register (LR[63:VA_SIZE]) are used to store a signature. Therefore, GDB
need to remove the signature to get backtraces.
GDB has support of pointer authentication. When pointer authenticaion is
enabled, GDB requests 8-bytes mask to the target to remove the
signature. mask[63:VA_SIZE] should be all set and mask[VA_SIZE-1:0]
should be all cleared. GDB removes the signature by addr&~mask or
addr|mask.
I added a feature to provide the mask for pointer authentication.

Antonio Borneo da34e36cdb nds32: drop it, together with aice adapter driver
The target nds32 and its companion adapter aice have not received
any real improvement since 2013.
It has been hard to keep them aligned during the evolution of
OpenOCD code, with no way for maintainers to really check if they
are still working.
No real documentation is present for them in OpenOCD.
The nds32 code triggers ~50 errors/warnings with scan-build.

The arch nds32 has been dropped from Linux kernel v5.18-rc1.

For all the reasons above, this code has been deprecated with
commit 2e5df83de7 ("nds32: deprecate it, together with aice
adapter driver") and tagged to be dropped before v0.13.0.

Let it r.i.p. in OpenOCD git history.

While there, drop from checkpatch list the camelcase symbols that
where only used in this code.

Antonio Borneo cc75aa37c5 openocd: add post-init and pre-shutdown helpers
It is a common requirement to automatically execute some command
after "init".
This can be achieved, either in scripts or through OpenOCD command
line, by explicitly calling "init" followed by the commands.
But this approach fails if the request for post-init commands is
spread across configuration files; only one of the files can split
pre-init and post-init status by calling "init".
The common workaround is to "rename" the command "init" and
replace it with a TCL proc that calls the original "init" and the
post-init commands. E.g. in Zephyr script [1].

To simplify and formalize the post-init execution, use a TCL list
that contains the list of commands to be executed. Every script
can contribute adding new commands, e.g. using "lappend".

In the same way, formalize the pre-shutdown execution with a TCL
list of user commands to be executed before OpenOCD exit.

Document them and add trivial examples.

Drop from documentation the suggestion to rename "shutdown".

Antonio Borneo b4f8d99c8d smp: deprecate legacy SMP core switching support
The deprecation was already in the documentation since v0.11.0
through commit 85ba2dc4c6 ("rtos/hwthread: add hardware-thread
pseudo rtos") but OpenOCD was not informing the user printing a
runtime message.

Remove the deprecated method from the documentation and print a
deprecated message at runtime.
There is no reliable way to print the same message in GDB console,
so we have to rely on user noticing it in the OpenOCD log.
Target is to remove the functionality after v0.12.0.

The device has compatible flash macro with STM32F1 family, reuse
stm32f1x driver code.

Detect non-ARM target - for simplicy test target type name 'riscv'
and the address has 32 bits.

In case of RISC-V CPU use simple chunked write algo - async algo
cannot be used as the core implemented in this device doesn't
allow memory access while running.

Antonio Borneo 2e5df83de7 nds32: deprecate it, together with aice adapter driver
The target nds32 and its companion adapter aice have not received
any real improvement since 2013.
It has been hard to keep them aligned during the evolution of
OpenOCD code, with no way for maintainers to really check if they
are still working.
No real documentation is present for them in OpenOCD.

The arch nds32 has been dropped from Linux kernel v5.18-rc1.

Deprecate both nds32 target and aice adapter with the target of
dropping them for v0.13.0.
Remove automatic build of aice, forcing user to select it.

Tarek BOCHKATI b9526f1401 semihosting: permit redirection of semihosting I/O to TCP
This command permits the usage of a TCP port to perform debug and stdio
operations:
 - debug : READC, WRITEC and WRITE0
 - stdio : READ, WRITE

This will permit the separation of semihosting message from OpenOCD log,
and separate semihosting messages per core.

syntax: arm semihosting_redirect (disable | tcp <port> [debug|stdio|all])

this allows to select which operations to be performed via TCP (debug,
stdio or all (default)).

Note: for stdio operations, only I/O from/to ':tt' file descriptors are
redirected.

tested using netcat on ubuntu

Marc Schink 38183dc856 target/tcl: Add 'read_memory' and 'write_memory'
These functions are meant as replacement for 'mem2array' and
'array2mem'.

The main benefits of these new functions are:

 * They do not use Tcl arrays but lists which makes it easier
   to parse (generate) the data. See the Python Tcl RPC code
   in contrib as a negative example.

 * They do not operate on Tcl variables but instead return (accept)
   the Tcl list directly. This makes the C and Tcl code base
   smaller and cleaner.

 * The code is slightly more performant when reading / writing
   large amount of data. Tested with a simple Python Tcl RPC
   benchmark.

Zoltán Dudás 5ab74bde06 semihosting: User defined operation, Tcl command exec on host
Enabling a portion (0x100 - 0x107) of the user defined semihosting
operation number range (0x100 - 0x1FF) to be processed with the help of
the existing target event mechanism, to implement a general-purpose Tcl
interface for the target available on the host, via semihosting
interface.

Example usage:
- The user configures a Tcl command as a callback for one of the newly
	defined events (semihosting-user-cmd-0x10X) in the configuration
	file.
- The target can make a semihosting call with <opnum>, passing optional
	parameters for the call.

If there is no callback registered to the user defined operation number,
nothing happens.

Example usage: Configure RTT automatically with the exact, linked
control block location from target.

Doug Brunner aad8718058 flash/nor/efr32: fixed lockbits and user data
Changed flash driver to support writing to the user data page, as well as to any portion of the lockbits page above 512 bytes (the amount used for the actual page lock words). The top part of the lockbits page is used on at least the EFR32xG1 chips for the SiLabs bootloader encryption keys.

As presented to the user, the lockbits page is the same size as the other pages, but any attempt to write to its low 512 bytes is an error. To enforce this, efr32x_write is renamed to efm32x_priv_write and a wrapper function is provided in its place. If the user erases the lockbits page, the driver rewrites the cached lock words after the erase. When the driver erases the lockbits page in order to update the lock words, it first takes a copy of anything stored in the top part of the page, and re-programs it after the erase operation.

There are now multiple instances of flash_bank for each target, and the flash_bank instances must share their cached lock words to operate as intended. Therefore, when a bank is created, the global flash bank list is used to find any other banks that share the same target. Since some banks in the global list are invalid at the time free_driver_priv is called, reference counting is used to decide when to free driver_priv.

To avoid the need to find the lockbits flash_bank from another flash_bank, efm32x_priv_write and efm32x_erase_page now take an absolute address.

There didn't seem to be any reason to prohibit unprotecting individual flash pages, so that limitation is removed from efm32x_protect().

This addresses ticket #185.

Valgrind-clean, except for 2x 4kiB not freed/still reachable blocks that were allocated by libudev.
No new Clang analyzer warnings, no new sanitizer warnings.
