+ * The 0xf1000000 is the default used by the recent, DT-capable, U-Boot
+ * bootloaders provided by Marvell. It is used in recent versions of
+ * DSM software provided by Synology. Nonetheless, some earlier boards
+ * were delivered with an older version of u-boot that left internal
+ * registers mapped at 0xd0000000. If you have such a device you will
+ * not be able to directly boot a kernel based on this Device Tree. In
+ * that case, the preferred solution is to update your bootloader (e.g.
+ * by upgrading to latest version of DSM, or building a new one and
+ * installing it from u-boot prompt) or adjust the Devive Tree
+ * (s/0xf1000000/0xd0000000/ in 'ranges' below).
