    Reserve some DDR DRAM for secure use on FVP platforms · 94574b5e
    Juan Castillo authored
    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
