[PATCH 3.11 133/208] arm64: dts: Reserve the memory used for secondary CPU release address

[Luis Henriques]

3.11.10.3 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Catalin Marinas <catalin.marinas at arm.com>

commit df503ba7f653c590b475ab80bde788edf5af70d5 upstream.

With the spin-table SMP booting method, secondary CPUs poll a location
passed in the DT. The foundation-v8.dts file doesn't have this memory
reserved and there is a risk of Linux using it before secondary CPUs are
started.
