Appended devicetree

Append devicetree

Append the devicetree to zImage to make a single Image which contains the kernel and the devicetree. This allows to use simpler bootloaders and minimizes errors that the bootloader can make.
cat ./arch/arm/boot/zImage ./arch/arm/boot/dts/tegra30-microsoft-surface-rt.dtb > ./arch/arm/boot/zImage
Your kernel with appended devicetree should be located at ./arch/arm/boot/zImage
