* 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.
