| * 0xd0000000). The 0xf1000000 is the default used by the recent, |
| * DT-capable, U-Boot bootloaders provided by Marvell. Some earlier |
| * boards were delivered with an older version of the bootloader that |
| * left internal registers mapped at 0xd0000000. If you are in this |
| * situation, you should either update your bootloader (preferred |
| * solution) or the below Device Tree should be adjusted. |
