-7. CONFIG_SYS_FULL_VA is used to enable 2-level page tables. For cores
-   supporting 64k pages it allows usage of full 48+ virtual/physical addresses

-   Enabling this option requires the following ones to be defined:
-       - CONFIG_SYS_MEM_MAP - an array of 'struct mm_region' describing the

-       - CONFIG_SYS_MEM_MAP_SIZE - number of entries in CONFIG_SYS_MEM_MAP
-       - CONFIG_SYS_PTL1_ENTRIES - number of 1st level page table entries
-       - CONFIG_SYS_PTL2_ENTRIES - number of 1nd level page table entries
-         for the largest CONFIG_SYS_MEM_MAP entry
