Help text

When enabled you can select a physical address to load the dtb from. Normally this address is passed by a bootloader such as u-boot but using this you can use a devicetree without a bootloader. This way you can store a devicetree in NOR flash or an onchip rom. Please note that this address is used directly so you have to manually do address translation if it's connected to a bridge. Also take into account that when using an MMU you'd have to ad 0xC0000000 to your address
