12 * Note: this Device Tree assumes that the bootloader has remapped the
13 * internal registers to 0xf1000000 (instead of the default
14 * 0xd0000000). The 0xf1000000 is the default used by the recent,
15 * DT-capable, U-Boot bootloaders provided by Marvell. Some earlier
16 * boards were delivered with an older version of the bootloader that
17 * left internal registers mapped at 0xd0000000. If you are in this
18 * situation, you should either update your bootloader (preferred
19 * solution) or the below Device Tree should be adjusted.
