This patch adds the ARM_LPAE and ARCH_PHYS_ADDR_T_64BIT Kconfig entries
allowing LPAE support to be compiled into the kernel.

Execute-In-Place allows the kernel to run from non-volatile storage
directly addressable by the CPU, such as NOR flash. This saves RAM

help
Say Y if you have an ARMv7 processor supporting the LPAE page
table format and you would like to access memory beyond the
4GB limit. The resulting kernel image will not run on
processors without the LPA extension.
If unsure, say N.
