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