Make Coresight Secure World Only

Hey,

I want to restrict access to the Coresight registers to the secure world, so the normal world OS can not tamper with the tracing. Is this generally possible, and if yes, how? I already tried to use the address space controller (TZC-400) with the memory-addresses of the registers, but that didn’t work, because it is only for protecting DDR-memory regions, as I later found out.

Best regards

Finn
