TZMP1 protected memory regions have been added in the Juno platform to
store sensitive data for the Arm(R) Ethos(TM)-N NPU
This is enabled when building TF-A with ARM_ETHOSN_NPU_TZMP1.
The NPU uses two protected memory regions:
1) Firmware region to protect the NPU's firmware from being modified
from the non-secure world
2) Data region for sensitive data used by the NPU
Respective memory region can only be accessed with their unique NSAID.
