Introduce a function to disable SPE feature for Non-secure state and do the default setting of making Secure state the owner of profiling buffers and trap access of profiling and profiling buffer control registers from lower ELs to EL3. This functionality is required to handle asymmetric cores where SPE has to disabled at runtime.
