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 #230
`gcc_setup.s` rebases the GOT and copies initialized data into the module data
area, but never applies the relocations the linker records for words inside that
data. A global initialized with a link-time constant -- `char *pBuffer = buffer;`,
a function pointer, a struct member holding a string literal's address -- kept
its link address and pointed outside the loaded module.
`gcc_setup.s` now walks `.rel.dyn` after the data copy and adjusts every
`R_ARM_RELATIVE` entry targeting the module data area, reusing the GOT loop's
base arithmetic and skip rules, and reloading the flash base first because
`crt0_memory_copy` clobbers `r3`.
The table is only emitted with `-pie`, so the example build scripts now pass
`-pie --no-dynamic-linker` and the example linker scripts discard `.dynamic`,
which `-pie` would otherwise place at address zero and inflate the image to
nearly 200 KB. Without `-pie` the table is empty and the loop is a no-op.
Covers Cortex-M3, M4, M7, M33 and M0+. Cortex-M23 ships no module linker or
build script and AArch64 uses a different relocation format; both left for a
follow-up.
Verified on `qemu-system-arm` with a module linked at one address and loaded at
another: char, function, string and struct-member pointers all resolve to the
loaded addresses, and the same module built without `-pie` still runs.

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.

The IAR multithreaded library support code allocates its file lock
mutexes from an array of _MAX_FLOCK entries, but the wrap-around check
and the exhaustion check in __iar_file_Mtxinit() both compared against
_MAX_LOCK, the bound of the unrelated system lock mutex array.
When _MAX_FLOCK is greater than _MAX_LOCK, the free mutex index wrapped
early and the exhaustion check reported failure while free entries
remained, so *m was set to TX_NULL and the application faulted the first
time a file lock was taken. When _MAX_FLOCK is smaller than _MAX_LOCK,
the free mutex index was allowed to run past the end of
__tx_iar_file_lock_mutexes and the exhaustion check could never fire.
Corrected all four comparisons in each of the 27 copies of tx_iar.c.
Fixes #444

This drops a few archive files from the source tree as they belong
to the toolchain.

The Arm Development Studio launch configurations and the IAR project files
carried absolute paths from the machines they were last opened on: four
individuals' home directories, a Broadcom support build tree, and directories
such as C:\release\threadx, C:\temp1702\tx and D:\threadx. They are published in
the repository and none of them resolves for anyone else.
In the launch files all of it is saved session state, which files that were never
opened in a debugger simply do not have:
breakpoints 72 files, saved breakpoints anchored to source
paths under cortex_a35 on one machine. Emptied
rather than deleted, matching the 27 launch files
that already carry an empty list.
scripts_view_script_links 70 files, a scripts view cache. The script the
launch actually runs is named one line earlier
through ${workspace_loc:...}, which is portable.
substitutePath 65 files, source lookup remapping. 30 map a path
to itself, and the rest point at one machine's
copy of libgloss or a build directory.
TREE_NODE_PROPERTIES 39 files, which rows the variables view had
expanded.
DebugCommandLine.History 2 files, the debug console command history,
including a typed absolute path.
The two IAR cases are not session state and are corrected rather than removed:
IarchiveOutput 23 files. The librarian output path pointed at
another machine, so the library was written
outside the project. Set to ###Unitialized###,
which 86 other option blocks already use, letting
IAR derive $EXE_DIR$\$PROJ_FNAME$.a.
IlinkIcfFile 1 file. The linker configuration file is load
bearing, so the file name is kept and the path
made project relative, as 33 other option blocks
spell it.
Seven of the files are ports_arch templates, so the generators would otherwise
have copied the paths back.
Verified: all 162 launch and IAR project files in the tree parse as well-formed
XML afterwards, no tracked launch or project file mentions any of the four user
names, and scripts/check_ports.sh passes, so the templates and their generated
copies still agree.

* 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.

Applied the standard MIT license header to all project-owned C, header,
assembly, shell, and Python files that were missing a copyright notice.
Third-party, toolchain startup, and auto-generated files were excluded.
