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