Hi All,


To align with PSA FF 1.0.0, the SPM needs to restart the entire system when some programmer error or panics are detected. So I had upstream a patch to add a system reset HAL function for SPM: https://review.trustedfirmware.org/#/c/trusted-firmware-m/+/2780/.


The basic idea is to add a weak common function so that the platform can use this weak function to do reset. Please note, the platform needs to add its own implementation if there is any different.


Unfortunately, there is no such test to test the system reset function curreetly. So please call psa_panic() in secure services for simple testing based on the top of this link: https://review.trustedfirmware.org/#/q/topic:tfm_panic+(status:open+OR+status:merged).


You can send mail or add comments directly in patches if you have any questions or comments.
