ThreadX still declares 6.5.1.202602 with hotfix 'a', which is the previous
release rather than the one being cut.
prepare_release.sh updated the five version constants in tx_api.h and the
version string in 211 port headers across ports, ports_smp, ports_arch and
ports_module. The hotfix letter is cleared, since the target has none. Nothing
else changed: every line in the port commit carries a version, and no file
outside an inc/tx_port.h was touched.
The port consistency checks passed before the branch was cut, which is what the
script gates on. Host regression 113/113 with zero warnings, and the AI
disclosure check passes.

The per-edit disclosure named the product and model, so every agent and every
model version appended another line. 74 files carried two to four of them, and
the same five products had accumulated 13 spellings -- Copilot against GitHub
Copilot, Claude Sonnet 4.6 against claude-sonnet-4.6, four spellings of Codex.
Twenty assembly lines carried a doubled comment marker, `; //` or `@ //`.
Every file now carries exactly one line, fixed text naming no product:
Portions of this file were generated with AI assistance.
It is written with the comment character that file already uses, so the `;`
and `@` assembly files keep theirs and the doubled markers are gone. Precise
attribution stays on the commit, where the Assisted-by trailer is per-change,
dated and attached to the diff it describes. A header line cannot hold that
record honestly, because the code it names gets rewritten and the line stays.
A file-level flag answers whether; the history answers who.
Comment-only. 455 files, 455 insertions and 574 deletions: every removed line
was a disclosure line, every added line is the fixed text, and no file is left
with zero or with more than one. `scripts/check_ports.sh` passes, including the
reproducibility check that would catch a ports_arch master and its generated
copies drifting apart. Recompiled against dev, every file that builds without a
vendor toolchain gives a byte-identical object: 19 of 19 C files under common,
100 of 100 GNU assembly files, and all 16 assemblable files whose comment
marker changed. The 10 remaining marker changes are ac5 and IAR sources where
`;` already started the comment and only the redundant `//` was removed.

Fixes #551
`_tx_thread_system_return_inline()` in the Cortex-M `tx_port.h` headers spells
its barriers `dsb 0xF` and `isb 0xF`. A bare hexadecimal operand is a GNU
assembler extension, and IAR rejects it with `operand syntax error`, so the
header cannot be included at all. The block is guarded for GCC, armclang and IAR
together, so every IAR user of an affected port hits it -- four independent
reports on Cortex-M33 and M7 with EWARM 9.50 and 9.70.
Both operands become `sy`, the Arm UAL name for exactly what `0xF` encodes. The
generated instruction is unchanged. Applied to the two `ports_arch` masters and
all 32 copies under `ports`, covering M0, M23, M3, M33, M4, M52, M55, M7 and M85
across ac5, ac6, gnu, iar and keil, plus the `scripts/check_ports.sh` probes that
matched the old spelling.
`check_ports.sh` passes, the copy scripts still reproduce every generated port
byte for byte, and `arm-none-eabi-gcc -O2` compiles a caller for every patched
header, emitting `dsb sy` and `isb sy`. Three headers that need toolchain
intrinsics GCC does not ship fail identically on `dev`.

the Cortex-M low-level initialization (#714)
_tx_initialize_low_level wrote VTOR and derived _tx_thread_system_stack_ptr from
the reset vector on every Cortex-M port. Programming VTOR is the job of the
low-level startup code that runs before the kernel is entered, and doing it again
inside ThreadX silently overrode a vector table that the application, a
bootloader or a firmware update had already installed. It also forced every
application to export a vector table symbol that the kernel itself never needed.
_tx_thread_system_stack_ptr is never read by any Cortex-M port, so the value
copied out of the reset vector served no purpose.
Both blocks are removed from all Cortex-M ports, together with the now-unused
symbol declarations. The GreenHills files keep the NVIC base address load that
the removed block used to leave in r0 for the SysTick setup that follows.
Applications that relied on ThreadX programming VTOR must now set it in their
startup code. The bundled examples link their vector table at address zero and
run on the reset default.

link lines (#618)
* Removed generated build output and stopped two scripts naming deleted archives
Three kinds of file in the tree are produced by a build rather than written by
hand, and one pair of scripts still links archives that were deleted years ago.
Keil writes ThreadX_Library.plg on every build; the two committed copies are
HTML build logs from someone's machine. Code Composer generates the makefiles
under ports/c667x/ccs/example_build/tx/Release from the project files beside
them, so makefile, objects.mk, sources.mk, subdir_rules.mk, subdir_vars.mk and
ccsObjs.opt are all regenerated output.
The arm9 and arm11 sample builds link libc.a, libgcc.a and, for arm11,
libnosys.a from their own example_build directories. Those archives were removed
in 6.1.10 under "Removal of unneeded files", and libnosys.a in #594, but the link
lines were never updated, so both examples fail immediately with
arm-none-eabi-ld: cannot find libc.a: No such file or directory
Link through the compiler driver instead, the shape every other example in the
tree uses since #594: the driver supplies libc and libgcc, and SYSCALL_LIB is
already defined in both scripts.
That does not make either example link, and the fix stops short of that on
purpose. With the archives no longer named, both now fail on
undefined reference to `_fini'
because their linker scripts define the .init and .fini sections but not the
_init and _fini symbols, which live in crti.o and crtn.o and are omitted by
-nostartfiles. Making those two old cores build is a separate question from
removing a stale reference, so they stay in EXAMPLES_EXPECTED_TO_FAIL, with the
comment there corrected: it blamed newlib multilib packaging, which is true of
cortex_r4 and cortex_r5 but was never the reason for arm9 and arm11.
Reproduced throughout with arm-none-eabi-gcc 13.2.1.

* Removed the Keil per-user state files and ignored them
Every Keil project in the tree carried a second file holding per-user state:
25 .uvoptx beside the 25 .uvprojx, 9 .uvopt beside the 9 .uvproj, and 3 .uvgui
multi-project workspace files. uVision rewrites all of them whenever a project is
opened, so they record whoever last had it open rather than anything about the
port: debugger selection, breakpoints, watch windows, window geometry.
Nothing in the tree references them, and every affected directory keeps its
.uvprojx or .uvproj, which is the file that actually describes the project.
Add ignore rules so they do not come back the next time someone opens a project
and commits.
1.4 MB across 37 files.

The Cortex-M ports under ports/ are generated. scripts/copy_armv7_m.sh copies
one tx_port.h and the per tool sources to fifteen M3, M4 and M7 targets, and
scripts/copy_armv8_m.sh does the same for nine M33, M55 and M85 targets. The
ports_arch_check workflow runs both scripts and fails if the tree is not
reproducible, so those copies are meant never to be edited directly.
They were. Every Cortex-M fix since #523 was applied to the generated copies
and not to the source, so the source fell behind and the check went red:
running the three scripts on dev changes 35 files. The check triggers only on
pull requests targeting master, which is why nothing caught it while the fixes
were merged into dev.
Left alone, the next run of these scripts would have reverted three separate
pieces of work: the memory barriers and clobbers from #523, the correction of
the IAR assembly header to use the assembler's own comment syntax, and the move
of tx_initialize_low_level.S into example_build for the M33, M55 and M85 GNU
ports from #514.
Bring the sources up to what the ports carry today, and regenerate. Two
behavioural changes come with that, both deliberate. The barriers from #523
reach the ac5 and keil variants of M3, M4 and M7, which were outside the scope
of that fix and never received it. The barrier that follows restoring the
interrupt posture, which #523 gave only to the GNU ports because GNU was the
only toolchain that could be tested, now applies to every tool; the identical
asm statement already shipped in the AC6 and IAR ports, so this adds a pipeline
flush rather than any new compiler exposure.
Regenerating also drops a stray #endif at the end of the Cortex-M85 IAR
tx_port.h, added by #523, which left that header with one more #endif than #if
and unable to compile. Every other ARMv8-M port was balanced.
Verified that the scripts are idempotent afterwards, that ports_arch_check
would pass, that no port loses a barrier or a clobber, that every regenerated
header is preprocessor balanced, and that every Cortex-M port covered by the
two scripts now carries the entry barrier.

* Add SysTick counter reset in Cortex-M ports
The SysTick counter value (SYST_CVR @0xE000E018) is indeterminate after
reset. Without clearing it prior to enabling the counter, the first tick
interval becomes unpredictable.
* Fixed missing comment and added generated-by header in Cortex-M0/AC6 port
Added the missing inline comment on the LDR r1, =0 instruction
(Build value for SysTick reset) and the required AI-generated
attribution comment under the copyright header.
