  47  * Note: this Device Tree assumes that the bootloader has remapped the
  48  * internal registers to 0xf1000000 (instead of the default
  49  * 0xd0000000). The 0xf1000000 is the default used by the recent,
  50  * DT-capable, U-Boot bootloaders provided by Marvell. Some earlier
  51  * boards were delivered with an older version of the bootloader that
  52  * left internal registers mapped at 0xd0000000. If you are in this
  53  * situation, you should either update your bootloader (preferred
  54  * solution) or the below Device Tree should be adjusted.
