[TF-A] V2.8 Release code freeze notification

Hi all,

As documented in the Release Cadence section of the TF-A documentation (https://trustedfirmware-a.readthedocs.io/en/latest/about/release-information...) the v2.8 release has an expected code freeze date of 3rd week of November 2022.

That equates to the start of that week Monday 14th November which is one calendar month away from tomorrow when the rc0 tag will be applied. Closing out the release takes around 6-10 working days normally over the last few releases.

We want to ensure that planned feature patches for the release are submitted in good time for the review process to conclude.

Preparations for v2.8 release is already underway.

Thanks

Joanna
