Preparing for OP-TEE 4.6.0

[BCC all OP-TEE maintainers]

Hi OP-TEE maintainers & contributors,

OP-TEE version 4.6.0 is scheduled to be released on 2025-04-25. So, now is a good time to start testing the master branch on the various platforms and report/fix any bugs.

The GitHub pull request for collecting Tested-by tags or any other comments is https://github.com/OP-TEE/optee_os/pull/7359.

We will create the release candidate tag 4.6.0-rc1 this Friday, allowing for a two-week testing period before the planned release.

You can find more information related to releases here: https://optee.readthedocs.io/en/latest/general/releases.html

Thanks, Jens
