Hello,
Thanks for the patch and the detailed commit message.
For ST boards, we usually treat this kind of issues with watchdog.
But I admit some watchdogs patches are still missing upstream.
I'll try to send them soon.
We are discussing internally to see if this particular use-case could be
done as you proposed.
I'll get back to you next week about this, when one of my colleagues
comes back.
Maybe this could be selected with a compilation flag.
About the patch submission, TF-A uses gerrit, and we do not merge
patches from mailing-list like Linux does.
Please check this page:
https://trustedfirmware-a.readthedocs.io/en/latest/process/contributing.html
Best regards,
Yann

Hi All,
The next release of the Firmware-A bundle of projects tagged v2.15 has an
expected code freeze date of 15/05/2026.
Refer to the release cadence section from TF-A documentation
(https://trustedfirmware-a.readthedocs.io/en/latest/about/release-informatio…).
Closing out the release takes around 6-10 working days after the code freeze.
v2.15 release preparation tasks are on-going and well progressed.
We want to ensure that planned feature patches for the release are submitted in
good time for the review process to conclude.
As a kind reminder and a matter of sharing CI resources, please launch CI
jobs with care e.g.:
*
For simple platform, docs changes, or one liners, use Allow-CI+1 label (no
need for a full Allow-CI+2 run).
*
For large patch stacks use Allow-CI+2 at top of the patch stack (and if
required few individual Allow+CI+1 labels in the middle of the patch stack).
*
Carefully analyze results and fix the change if required, before launching new
jobs on the same change.
*
If after issuing a Allow-CI+1 or Allow-CI+2 label a Build start notice is not
added as a gerrit comment on the patch right away please be patient as under
heavy load CI jobs can be queued and in extreme conditions it can be over an
hour before the Build start notice is issued. Issuing another Allow-CI+1 or
Allow-CI+2 label will just result in an additional job being queued.
Thanks & Regards,
Harrison on behalf of the TF-A team
