NS<->S communication code abstraction
Open, Needs TriagePublic

Description

Current TFM code assumes the veneer to be the default way communication between NSPE and SPE.
The message passing mechanism needs to be abstracted from the core TFM implementation.

[Design: TBD]
Rough flow:

mbox_ISR() {

retrieve_ns_req();
post_ns_req_to_main_thread()

}

secure core main()
{

while (1) {
 wait_for_interrupt();
 dequeue_req();
 tfm_dispatch_req_to_spm();

}
