Does TZASC still work in ARMv9 when RME is implemented?

Recently I have some questions when reading document about CCA:

In ARMv9, when RME is implemented, we can use GPT to divide memory into different regions and manage them. In this scenario, whether TZASC can still be used to do something or not?

Thanks & Regards

  • The design of RME allows that TZ can be still run seperately as before. 

    TZASC can be still used in TZ secure state to provide secure/non-secure access control for Trustzone applications.

    TZASC is not intentedly used for RME Root and Ream secure state.
