Hi all,

I’d like to submit the patches to enable multiple NS PSA client calls feature on dual-cpu system *by this week*, if no more comments.

The patches have been reviewed for several rounds in last two months. Thanks a lot for all your reviews, comments and validation.

The patch set can support NS side to start multiple outstanding PSA client calls concurrently, on dual-cpu system. The feature is enabled and verified on Cypress PSoC 64 platform.

If you are interested, please take a look at https://review.trustedfirmware.org/q/topic:%22dualcpu-multi-client-call%22+(status:open%20OR%20status:merged).

The overall design is discussed in design documents https://git.trustedfirmware.org/trusted-firmware-m.git/tree/docs/design_documents/mailbox_design_on_dual_core_system.rst and https://git.trustedfirmware.org/trusted-firmware-m.git/tree/docs/design_documents/communication_prototype_between_nspe_and_spe_in_dual_core_systems.rst

Comments and suggestions are still and always welcome. 😊

Thank you.

Best regards,

Hu Ziji
