Hi All,

This is a follow-up email to the OP-TEE 3.19 release, highlighting the updates to the SPMC and related components.

Short summary of introduced changes: - Added support for running SPs loaded from the FIP (by TF-A). This is an alternative to the current embedded SP loading mechanism [1]. - Added a new suite to xtest (ffa_spmc) to enable testing the SPMC as part of the normal OP-TEE test procedure [2].

For more details on how to get, build and test the SPMC, please see [3]. Our 3.19 release related test results are captured on this page [4].

Regards, Balint
