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
