[TF-A] TF-A 2.5 Release: Code-Freeze 30th April

Hi,

This is to notify that we are planning to target the Trusted Firmware-A 2.5 release during the second week of May 2021 as part of the regular ~6-month cadence. The aim is to consolidate all TF-A work since the 2.4 release. As part of this, a release candidate tag will be created and release activities will commence after the 30th of April. Essentially we will not merge any major enhancements from this date until the release is made. Please ensure any Gerrit Patch Reviews desired to make the 2.5 release are submitted in good time to be complete by last week of Apr 2021. Any major enhancement Gerrit Patch Reviews still open after that date will not be merged until after the release.
