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. | |
