Phil Elwell b0804ed0ca ARM: dts: bcm283x: Reserve first page for firmware 
The Raspberry Pi startup stub files for multi-core BCM283X 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.
