Antonio Borneo 6a81bad3b9 configure: split build of hla layouts
Current hla driver supports two "layout": stlink and ti-icdi.
The configure script allows to independently enable/disable the
the two layout. But in reality by selecting only one of them the
whole hla driver is built, including both "layouts".
This is currently not a big issue because the dependencies of the
two layout are the same (libusb), so we are sure that selecting
one of them would permit to build both.
This is going to change with the merge of a third "layout" for
Nuvoton Nu-Link, because it would be based on hidapi.
We need, at least, to decouple the build of libusb and hidapi
"layouts". A full decouple of each "layout" is also welcome to
match the selection done during configure.

Introduce a new automake macro for each of the two "layout" and
use them to conditionally build the "layout" files.
Use the existing autoconf macros to conditionally compile the code
that depends by the "layout".

Switch to a time based check, add an explicit yield, and report an

Antonio Borneo 7c88e76a76 target: do not print an error on shutdown in target events
Before commit b3ce5a0ae5 ("target: use LOG_USER to print errors
in events") an error in an event handler was silently lost, while
now the associated message is printed out.

A "shutdown" command in a target event (e.g. in gdb-detach) causes
the event to end with error code ERROR_COMMAND_CLOSE_CONNECTION,
that triggers the error message:
	shutdown command invoked
	Error executing event <event-name> on target <target-name>:

The error code returned by the command "shutdown" is required to
stop the execution in a script/proc and avoid executing any
further command in the script/proc.
It is then normal to get an error code from the "shutdown" command
and it should not be printed out.

Intercept the return code of the event in case of "shutdown", then
skip scheduling other target events and return without printing
the incorrect error message.

Moritz Fischer 64733434e2 jtag: drivers: xlnx-pcie-xvc: Add support for SWD mode.
Add support for SWD debug to the Xilinx XVC/PCIe driver.

This is possible since the device is essentially a shift-register.
So doing SWD vs JTAG is a matter of wiring things correctly on the
RTL side (use TMS for SWDI, TDO for SWDO).

The clang static checker doesn't find any new problems with this change.

Edward Fewell 11116ef6ad target/icepick.cfg: Add support for Test TAPs in ICEPick C
In addition to the debug TAPs, the ICEPick C also supports
a bank of Test TAPs (limited functionality intended for
non-debuggable targets). Added support for Test TAPs to
the icepick_c_tapenable routine. Port numbers of 0 to 15
will continue to be handled as a debug TAP number. Test
TAPs will be port numbers of 16 to 31.

This functionality will be needed for doing a flash
mass erase on CC26xx/CC13xx targets. It is possible
for user application to block even adding the Cortex M
TAP to the scan chain, so the only way to unbrick the
target and erase the flash is using a component on a
test TAP of the device's ICEPick router.

Tarek BOCHKATI 9a690c6bdb openocd: fix issue in WIN32 with TCP adapters
Issue: server_quit is called before adapter_quit:
  In WIN32 only in server_quit we do an WSACleanup,
  which terminates/closes all active sockets.
  So if the adapter is TCP based, the adapter.quit handler
  will fail if it will need to send some commands through TCP.

Example: close_socket in jtag_vpi_quit will fail in WIN32
  because the socket is already closed
  and the errno is set as "Bad File Descriptor"

To fix that we introduced new functions called server_host_os_entry/quit
to manage specific OS setup (hence WSA for sockets in WINDOWS) in order
to delay WSACleanup after adapter_quit().

("armv7m: Fix memory leak in register caching.").

The same allocation is also used by target types "arm7tdmi",
"arm9tdmi", "arm11" and "xscale" but they all lack the deinit
method and I do not have relevant HW to test the fix. For such
reasons they are not addressed in this patch.

Antonio Borneo 061cae171c target/mem_ap: fix two memory leaks
The target mem_ap misses the method 'deinit_target' and does not
free the memory allocated during 'target create' and 'configure'.

Add the missing method and free the allocated memory.
Issue identified with valgrind.

Antonio Borneo f6b4079ce5 libusb_helper: fix memory leak when no adapter is found
When jtag_libusb_open() fails to find the adapter, it returns
error but left libusb initialized causing memory leak of libusb
internal data.
Issue found with valgrind when no adapter or board is connected to
the host, e.g.
	valgrind openocd -f board/st_nucleo_f4.cfg

Close the libusb operations if jtag_libusb_open() has to return
error.

Antonio Borneo 37330f89d7 target/cortex-m: enable C_DEBUGEN during examine
Current code for Cortex M does not set C_DEBUGEN as soon as
possible, (which means during target examine), but later-on either:
1) at command 'halt' (e.g. for 'gdb-attach' event);
2) at command 'soft_reset_halt';
3) at commands 'reset', 'reset halt' or 'reset init';
4) during polling, but only if the target:
    = enter in 'double fault', or
    = exit from a reset, or
    = halts (not possible if C_DEBUGEN is not set)

Plus, if commands in 1) or 2) are executed before the very first
poll of the target, the value of 'cortex_m->dcb_dhcsr' is used not
initialized while writing it back in DCB_DHCSR.

Another side effect of this situation is that it's possible to set
a HW breakpoint with the target running, while C_DEBUGEN is not
set. Accordingly to [1], C1.3.1 "Debug authentication":
    When DGBEN is LOW and DHCSR.S_HALT == 0:
    ...
    FPB breakpoints do not generate an entry to Debug state and,
    if no DebugMonitor exception is generated, will escalate to
    HardFault, Lockup, or be ignored.
On STM32MP15x I get HW breakpoint ignored, while on STM32F411 I
get HardFault.
E.g. following these steps:
- power-on a pre-flashed board that starts running the firmware;
- connect openocd, without halting or resetting the board;
- set a HW breakpoint to some address often executed;
- wait, but the board doesn't halt ...;
- type the command 'halt';
- if the Cortex-M has HardFault it would be visible and the fault
  is at the breakpoint address;
- if no HardFault then type the command 'resume';
- wait and the board will finally halt at the HW breakpoint.

A similar issue has been detected on Cortex-A code and fixed by
commit bff87a7f28 ("target/cortex_a: enable DSCR_HALT_DBG_MODE
during examine").
Follow the same approach and set C_DEBUGEN during examine.
Also, initialize 'cortex_m->dcb_dhcsr' during examine.

Antonio Borneo 1fa66d3633 log: fix kept_alive() and report expired timeout
The kept_alive() function is called to inform the keep-alive code
that a keep-alive as been just kicked through some other path.
But kept_alive() erroneously resets the timeout counter without
checking if it has already expired, thus masking a potential
timeout.

Check if timeout counter has expired during kept_alive().
While there, put the timeout values in macros and explicit the
units in the timeout messages.

Antonio Borneo ffc1ca4b91 nor/kinetis: add keep-alive during flash write
Flashing Kinetis MCU MK22FX512VLH12 takes longer than one second,
thus gdb connection can timeout. Before commit 7f260f5009
("helper/command: Handle Tcl return values consistently") the
openocd timeout warning was masked by a bug in gdb_put_packet()
that resets the timeout counter if any message is logged out.
The commit above removes one log message and the timeout warning
is now triggered.

While the bug in gdb_put_packet() is still to be fixed, the reason
of the timeout is the lack of keep_alive() calls in kinetis flash
driver.

Add keep_alive() call at every iteration in function
kinetis_write_sections(), that is reported as core write function
in chunks of 1024 bytes in the log from the reporter.
Add also a keep_alive() call at every iteration in function
kinetis_write_inner(). This part is not present in the log but, by
code analysis, it represents another critical loop.

For jtag/drivers/bcm2835gpio dev_mem_fd has been updated within
bcm2835gpio_init with the add on of gpio to mem. This permits the
access to memory of GPIO without the need for root access.
For failed attempt, a fallback to original memory follows.
It should be noted that any printed error is relative to original
