Adds start address and size config options for setting aside a portion of the EMIF memory space for usage by security software (like a secure OS/TEE). There are two sizes, a total size and a protected size. The region is divided into protected (secure) and unprotected (public) regions, that are contiguous and start at the start address given. If the start address is zero, the intention is that the region will be automatically placed at the end of the available external DRAM space. Signed-off-by: Daniel Allred <d-allred@ti.com>

using hardware memory firewalls. This value must be smaller than the
