    rpi3: Add mem reserve region to DTB if present · 5341b42e
    Antonio Nino Diaz authored
    When a device tree blob is present at a known address, instead of, for
    example, relying on the user modifying the Linux command line to warn
    about the memory reserved for the Trusted Firmware, pass it on the DTB.
    
    The current code deletes the memory reserved for the default bootstrap
    of the Raspberry Pi and adds the region used by the Trusted Firmware.
    
    This system replaces the previous one consisting on adding
    ``memmap=16M$256M`` to the Linux command line. It's also meant to be
    used by U-Boot and any other bootloader that understands DTB files.
