Hi all,

As you may be aware, implementing the PSA Internal Trusted Storage (ITS) APIs is on the TF-M roadmap for this quarter (https://developer.trustedfirmware.org/w/tf_m/planning/). We plan to implement these APIs with a new TF-M Internal Trusted Storage service.

The design proposal for the new TF-M ITS service is now available for design review here: https://review.trustedfirmware.org/c/trusted-firmware-m/+/1604 . The design is currently in "draft" state, which means further refinements are to be expected, and feedback is welcome.

For more information about the PSA ITS APIs themselves, the PSA Storage API document may be downloaded from here: https://pages.arm.com/PSA-APIs

Kind regards, Jamie
