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.

comments that describe what the code actually does (#735)
The context save, vectored context save and system return routines in the
ARMv7-A ports carried pseudo-code comments claiming that they saved the
thread stack pointer and then switched to _tx_thread_system_stack_ptr.
Neither of those things happens, and none of these ports references that
variable outside an unused IMPORT in their example builds.
On ARMv7-A each processor mode has its own banked stack pointer. The IRQ
handler branches to _tx_thread_context_save while still in IRQ mode, so the
core's banked IRQ stack already serves as the system stack, and the thread
stack pointer is stored in the control block by _tx_thread_context_restore,
and only when the interrupt results in preemption. The scheduler runs on the
banked SVC mode stack that the startup code sets up. There is nothing for a
software stack switch to do.
The comments were therefore misleading rather than merely redundant, and had
led at least one user to try to restore the code they described. They are now
replaced by a description of the actual mechanism.
The AArch64 SMP ports keep their comments unchanged, because ARMv8-A does not
bank a stack pointer per processor mode and those ports do reload
_tx_thread_system_stack_ptr[core] explicitly.
This is a comment-only change. Every changed line is a comment, and all
twenty-five GNU variants still assemble cleanly for their target core.
The fourteen files under ports/cortex_a{5,7,8,9,12,15,17} were regenerated
from ports_arch/ARMv7-A/threadx/common/src/tx_thread_system_return.S with
ports_arch/ARMv7-A/update.sh. The ARMv7-A SMP ports have no generator, so
those files were edited directly.
Fixes #734

* Fixed Cortex-A9 SMP time source
Updated Cortex-A9 SMP timestamp reads to use the global timer low counter instead of the decrementing private timer counter. Applied the change to GNU and AC5 ports.
* Fixed remaining Arm SMP time sources
Updated Cortex-A5, Cortex-A7, and Cortex-R8 SMP timestamp hooks so execution profiling uses incrementing time sources instead of the decrementing private timer count register.
Cortex-A5 and Cortex-R8 now read the global timer count low register, matching the Cortex-A9 fix. Cortex-A7 now reads the generic timer physical count register.

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.
