Subject: [PATCH AUTOSEL for-4.9 37/53] arm64: dts: NS2: reserve memory for
 Nitro firmware

From: Jon Mason <jon.mason@...adcom.com>

[ Upstream commit 0cc878d678444392ca2a31350f89f489593ef5bb ]

Nitro firmware is loaded into memory by the bootloader at a specific
location.  Set this memory range aside to prevent the kernel from using
it.
