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