The SoC memory map view shown in Memory Map is used by A53SS0_CORE0 and A53SS0_CORE1 but there are processors which support only 32-bit addressing and cannot access higher address ranges. For these processors RAT modules are integrated to remap the 32-bit addresses to 48-bit addresses allowing higher address range accesses. The "RAT_REGION" regions shown in R5FSS0/1 Memory Map through MCU_M4FSS) Memory Map are dedicated to RAT remapping.
For more information about the RAT module, see Region-based Address Translation (RAT) Module.
