Subject: arm64: dts: NS2: reserve memory for Nitro firmware
From: Jon Mason <jon.mason@xxxxxxxxxxxx>
[ 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.
