Summer,
The email I sent with the attachment was bounced back so I sent another one afterwards that detailed the changes I had to make. I’d rather someone on your team make the corrections to make sure they’re sufficient.

Hi Alan,
Thanks for pointing out this issue.
The patch related to PSA APIs alignment task is the first patch to align the PSA APIs, we will have some following patches to update. In your last email, I didn't see the attachment, maybe blocked by the system. If it is convenient for you, could you push your patch to https://review.trustedfirmware.org , or you can create one ticket in https://developer.trustedfirmware.org and upload your changes as attachment in the new created task. Attached the change under my task T435 is also OK. We can help to submit the changes for you.
Thanks, Summer

I found several other code points in tfm_svcalls.c that need to be enhanced to handle 'type' >= PSA_IPC_CALL.
Attached is my modified tfm_svcalls.c file. With these modifications, the 'type' argument makes its way through the system without causing tfm_panic() to be invoked.

In order to pass along the new ‘type’ argument in psa_call, it seems that this line in tfm_svcalls.c:
msg = tfm_spm_create_msg(service, handle, PSA_IPC_CALL, ns_caller, invecs, in_num, outvecs, out_num, outptr);Should be:
msg = tfm_spm_create_msg(service, handle, type, ns_caller, invecs, in_num, outvecs, out_num, outptr);Otherwise the receiving SP will always see msg.type == PSA_IPC_CALL.
