A prototype PSA API implementation was pushed into ‘feature-ipc’, which showcases PSA API usage. This implementation did not considerate real secure partition usage; and only partial PSA APIs were implemented.
An updated Full IPC implementation is required. In updated implementation:
• IPC secure partition has its own thread and call PSA APIs in thread entry.
• A scheduler and message buffer are implemented in SPM.
• IPC secure partition is generated from manifest (Partial with some handcraft, since still need deep modification within manifest part but ideas are not totally gathered).
• All PSA APIs implemented.
