Porting linux on Cortex R52 FVP

The Arm Cortex-R52 processor delivers high performance 32-bit processing offering efficient code density combined with the highest level of integrated capability for functional safety of any Arm processor.

The Cortex-R52 processor meets the rising performance needs of advanced real-time embedded systems. As the first Armv8-R processor, Cortex-R52 introduces support for a hypervisor, simplifying software integration with robust separation to protect safety-critical code.

Cortex-R82 64-bit real-time processor is Linux-capable because it contains MMU while Cortex-R52 doesn't have. 
The default Linux code assumes there is a MMU component in the processor. So if you want to enable Linux for Cortex-R52, you have to do some Linux customization changes by yourselves as there is no generic way.
