The issue is that I'm not sure we can represent in the same DT both MPU and DSP view, since the DT root is supposed to represent a processor. If we need the real DSP viewpoint, we will have to mostly duplicate the MPU view then remove MPU private peripherals and add the DSP private peripherals. Regards, Benoit
