Secure memory is at the end of memory, separated and reserved from OS, tracked by gd->secure_ram. Secure memory can host MMU tables, security monitor, etc. This is different from PRAM used to reserve private memory. PRAM offers memory at the top of u-boot memory, not necessarily the real end of memory for systems with very large DDR. Using the end of memory simplifies MMU setup and avoid memory fragmentation. "bdinfo" command shows gd->secure_ram value if this memory is marked as secured. Signed-off-by: York Sun <yorksun@freescale.com>
