The Central Security Unit (CSU) allows secure world software to change the default access control policies of peripherals/bus slaves, determining which bus masters may access them. This allows peripherals to be separated into distinct security domains. Combined with SMMU configuration of the system masters privileges, these features provide protection against indirect unauthorized access to data.
For now we configure all the peripheral access permissions as R/W.
