0013 * internal registers to 0xf1000000 (instead of the default
0014 * 0xd0000000). The 0xf1000000 is the default used by the recent,
0015 * DT-capable, U-Boot bootloaders provided by Marvell. Some earlier
0016 * boards were delivered with an older version of the bootloader that
0017 * left internal registers mapped at 0xd0000000. If you are in this
0018 * situation, you should either update your bootloader (preferred
0019 * solution) or the below Device Tree should be adjusted.
