	  used by applications to set aside private regions (so-called Secure Enclaves) of
	  code and data.

	  PRMRR (Protected Memory Range) is the space in RAM that is used to provide a protected
	  memory area (e.g. for the Intel SGX Secure Enclaves). The memory region is accessible
	  only by the processor itself to protect the data from unauthorized access.

	  This option selects the maximum size that gets reserved. Depending on the SoC a lower,
	  compatible value may be chosen at runtime as not all values are supported on all
	  families.
