It is used in recent versions of 48 * DSM software provided by Synology. Nonetheless, some earlier boards 49 * were delivered with an older version of u-boot that left internal 50 * registers mapped at 0xd0000000. If you have such a device you will 51 * not be able to directly boot a kernel based on this Device Tree. In 52 * that case, the preferred solution is to update your bootloader (e.g. 53 * by upgrading to latest version of DSM, or building a new one and 54 * installing it from u-boot prompt) or adjust the Devive Tree 55 * (s/0xf1000000/0xd0000000/ in 'ranges' below). 56 */ 57 58/dts-v1/;
