Nonetheless, some earlier boards 12 * were delivered with an older version of u-boot that left internal 13 * registers mapped at 0xd0000000. If you have such a device you will 14 * not be able to directly boot a kernel based on this Device Tree. In 15 * that case, the preferred solution is to update your bootloader (e.g. 16 * by upgrading to latest version of DSM, or building a new one and 17 * installing it from u-boot prompt) or adjust the Devive Tree 18 * (s/0xf1000000/0xd0000000/ in 'ranges' below). 19 */ 20 21/dts-v1/;
