    ARM: dts: bcm283x: Reserve first page for firmware
    
    The Raspberry Pi startup stub files for multi-core BCM27XX processors
    make the secondary CPUs spin until the corresponding mailbox is
    written. These stubs are loaded at physical address 0x00000xxx (as seen
    by the ARMs), but this page will be reused by the kernel unless it is
    explicitly reserved, causing the waiting cores to execute random code.
    
    Use the /memreserve/ Device Tree directive to mark the first page as
    off-limits to the kernel.
    
    See: raspberrypi/linux#1989
