Reserve some DDR DRAM for secure use on FVP platforms
TZC-400 is configured to set the last 16MB of DRAM1 as secure memory and the rest of DRAM as non-secure. Non-secure software must not attempt to access the 16MB secure area. Device tree files (sources and binaries) have been updated to match this configuration, removing that memory from the Linux physical memory map. To use UEFI and Linux with this patch, the latest version of UEFI and the updated device tree files are required. Check the user guide in the documentation for more details. Replaced magic numbers with #define for memory region definition in the platform security initialization function. Fixes ARM-software/tf-issues#149 Change-Id: Ia5d070244aae6c5288ea0e6c8e89d92859522bfe
