  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.
