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