    target: cortex-m: fix support for armv8m caches
    
    Scan-build is unable to correctly follow the deferred loading of
    queued read, finalized by the atomic write, thus it incorrectly
    claims that the arrays d_u_ccsidr[] and i_ccsidr[] could carry
    not initialized values:
    
            armv7m_cache.c:154:31: warning: 1st function call argument
            is an uninitialized value [core.CallAndMessage]
               cache->arch[cl].d_u_size = decode_ccsidr(d_u_ccsidr[cl]);
    
            armv7m_cache.c:172:29: warning: 1st function call argument
            is an uninitialized value [core.CallAndMessage]
               cache->arch[cl].i_size = decode_ccsidr(i_ccsidr[cl]);
    
    Initialize the arrays to zero to hide these false positive.

    helper/log: mark 'fmt' argument of alloc_*printf() as not NULL
    
    Even after commit e12ceddd5ee4 ("helper/log: mark `fmt` argument
    of `alloc_vprintf()` as format string"), the GCC compiler still
    reports that alloc_vprintf() could call vsnprintf() with a NULL
    format parameter.
    
    Inform the compiler that alloc_vprintf() cannot accept NULL as
    format string.
    Add an assert() in alloc_vprintf() so even compilers that do not
    use the function attribute 'nonnull' will play safe.
    While there, extend the same fixes to alloc_printf() too.

    openocd: don't test 'debug_level' directly
    
    Use the macro 'LOG_LEVEL_IS()' to test 'debug_level'.
    
    While there, use the macro 'LOG_LVL_*' in place of the numeric
    value.
    
    Skip all riscv code, as it is going to be updated soon from the
    external fork.

    adapters/cmsis-dap: Fix build without libusb
    
    The cmsis-dap core driver depends on libusb-related code which breaks
    the build when libusb is not available.
    
    Remove libusb dependency of the core driver to fix the build issue. For
    now, use an own timeout #define with the value of LIBUSB_TIMEOUT_MS but
    timeout handling should be better moved to the backends. However, this
    should be addressed in a dedicated patch.

    configure.ac: rename 'adapterTuple' as 'adapter_driver'
    
    Commit ce3bf664c815 ("configure.ac: rename M4 macro 'adapter' to
    prevent accidental conflicts") renames the macro as 'adapterTuple'
    but since the macro name is printed in error messages, this
    creates cryptic errors like:
            configure: error: header sys/mman.h is required
            for adapterTuple "Bitbanging on EP93xx-based SBCs".
    
    Rename it as 'adapter_driver'. It keeps valid the purpose of the
    former renaming, while keeping readable the error message.

    configure.ac: add adapter dependency from sys/mman.h
    
    The adapter's driver that require the header file sys/mman.h
    should check for it and don't compile if it is not present.
    
    Add the check for sys/mman.h in configure.ac and prevent the
    build of the adapter's driver that depend on it.

    adapter/parport: Add device file support
    
    Allow to specify the parallel port by its device file. Deprecate port
    number support but keep it for backward compatibility.
    
    This is one necessary step to remove direct I/O support for the parallel
    port driver.
    
    While at it, consistently return ERROR_JTAG_INIT_FAILED in case of a
    failure in parport_init().

commit 39ed0b0bbaac63c88d1e4b9ffe85e209bdb6b059
Author: Marc Schink <de...@za...>
Date:   Sun Aug 17 14:11:39 2025 +0000

    adapter/parport: Deprecate direct I/O support
    
    We deprecate direct I/O support in favor of ppdev for the following
    reasons:
    
      - Linux supports ppdev since ~2.4 (released ~24 years ago) and it is
        enabled by default on major distros (Ubuntu, Fedora). So it is
        effectively ubiquitous
      - FreeBSD provides no direct I/O support, so ppdev (ppi) is the only
        viable option
      - Direct I/O requires root/elevated privileges which is inadvisable
      - Removing direct I/O reduces build and driver complexity and yields
        a smaller, easier-to-maintain codebase
      - Supporting only ppdev allows us to simplify the codebase by using
        device files (e.g., /dev/parport0) instead of numeric identifiers
    
    Windows is the only rationale to keep direct I/O, but the user base
    appears minimal to nonexistent and no active contributors can test the
    Windows driver.

commit 382f067b6ee51229d8b502362722fa22d36edcfe
Author: Marek Kraus <gam...@ou...>
Date:   Sat Mar 22 15:36:45 2025 +0100

    tcl/target: add Bouffalo Lab BL616 chip series support
    
    Adds support for BL616 series of chips, BL616 and BL618.
    No flash bank support yet.
    
    BL616 in comparison with BL602-series have new architecture,
    using T-Head E907 RISC-V cores, instead of SiFive ones.
    
    As BL602-series, the ndmreset bit in RISC-V Debug Module
    does not reset the chip as it should, so we need to do it
    manually with registers almost the same way as in BL602.
    
    Additionally, JTAG Debug Transport Module in the chip have wrongly
    implemented Test-Logic-Reset state, causing automatic chain scan
    not working at all after initial JTAG usage. This is because
    Test-Logic-State do not set IR instruction to IDCODE,
    as it should by JTAG spec. We can fix this by getting state machine
    to known state and configure IR instruction manually to IDCODE.
    This bug was so far found in T-Head C906 and E907 IP cores.
    
    This patch was tested heavily and works reliably on
    BL616, BL618 and QCC74X.

    README: add instructions for missing INSTALL file
    
    The file INSTALL has been dropped in 2009 with [1] and it has been
    replaced by the INSTALL file generated by automake.
    The file INSTALL is only present in official releases of OpenOCD
    and not in the code cloned from git.
    
    Add a note in README to report this inconsistency.

    jtag/ch347: Refine driver and configs for EasyDevKits adapters
    
    This commit improves support for CH347-based JTAG adapters:
    
    - configure.ac: removed "Mode3" restriction (CH347F does not require mode).
    - configs: added board config for ESP32-WROVER-E WCH JTAG DevKit and
      ESP32-WROVER-E FTDI JTAG DevKit
    - ch347 driver: removed `ch347 activity_led` command; activity LED
      is now controlled via the generic `adapter gpio led` command.
    - doc/openocd.texi: updated documentation accordingly.

    target: cortex-m: add support for armv8m caches
    
    Cores like Cortex-M7, Cortex-M55 and Cortex-M85 can have either
    D-Cache and/or I-Cache.
    Using SW breakpoints in RAM requires handling these caches.
    
    Detect the presence of cache at examine.
    Detect cache state (enable/disable) at debug entry.
    Take care of caches synchronization through the PoC (usually the
    SRAM) while setting and removing SW breakpoints.
    Add command 'cache_info' to check cache presence and size.

commit 2abf8daa80d31dc78877943ad580af7a6fbbbe3f
Author: Marc Schink <de...@za...>
Date:   Mon Apr 15 07:48:31 2024 +0200

    target/cortex_m: Remove echo of 'reset_config' command
    
    Do not echo the selected reset config. This is one of many changes to
    make the behavior of Tcl commands more consistent.
    
    This also avoids stray and confusing messages in the output of OpenOCD.
    For example, the "reset_config" line here:
    
      Open On-Chip Debugger 0.12.0+dev-00802-gb7f0145fc-dirty
      Licensed under GNU GPL v2
      For bug reports, read
            http://openocd.org/doc/doxygen/bugs.html
      cortex_m reset_config sysresetreq
      Info : Listening on port 6666 for tcl connections
      Info : Listening on port 4444 for telnet connections
    
    While at it, fix some coding style and command handling issues.

commit e5888bda38f4952e2ae92f7dc5b25fc9a2d1c2b3
Author: Samuel Obuch <sam...@es...>
Date:   Mon Aug 18 22:05:55 2025 +0200

    target/breakpoints: drop duplicate breakpoint/watchpoint "clear_target" functions
    
    We need to cleanup watchpoints on all targets in SMP group when GDB
    connects. Otherwise, the targets will not be consistent.
    Once thats fixed, both *_clear_target functions clearly duplicate
    the corresponding *_remove_all functions.

    jtag/drivers/cmsis_dap_tcp: fix socket handling for Windows
    
    Windows does not support socket recv() with a combination of MSG_PEEK
    and MSG_WAITALL flags. Work around this limitation in a way that works
    for both Windows and other platforms.

    jtag: linuxgpiod: use libgpiod v2 API for gpiod_line_request()
    
    Work in progress. Target is to replace v1 gpiod_line_request()
    
    Define and use dummy functions from v2 for v1:
    - gpiod_line_config_new(),
    - gpiod_line_config_free(),
    
    Not yet used:
    - gpiod_line_config_add_line_settings(),
    - gpiod_chip_request_lines().

    jtag: linuxgpiod: wrap gpiod_request_config from libgpiod v2
    
    Reorganize the code of helper_get_line() for label err_out.
    Define and use dummy functions from v2 for v1:
    - gpiod_request_config_new(),
    - gpiod_request_config_free(),
    - gpiod_request_config_set_consumer().

    Some target, like aarch64, has more than one bank of registers.
    
    Let the commands 'get_reg' and 'set_reg' to search the register
    name in all banks, as is already done in command 'reg'.
