[TF-A] How to trap aborts caused by TZASC?

Hi all,

I want to test how to trap the aborts caused by TZASC. For example, when I use NS-EL1 (e.g., OS) to access a Secure region (configured in TZASC), it will generate an abort.

But I am not sure how to trap it. I think it is an external abort, so I enable the SCR_EL3.EA=1 and write a handler. However I cannot trap it. Also, my other handlers in EL3 still do not report the abort.

Thus, how can I trap a TZASC abort? If I want to route it into EL3 to handle, how can I do it?

Sincerely, WANG Chenxu
