| * Note: this Device Tree assumes that the bootloader has remapped the |
| * internal registers to 0xf1000000 (instead of the old 0xd0000000). |
| * 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). |
