* Note: this Device Tree assumes that the bootloader has remapped the
|
|
* internal registers to 0xf1000000 (instead of the old 0xd0000000).
|
|
* The 0xf1000000 is the default used by the recent, DT-capable, U-Boot
|
|
* bootloaders provided by Marvell. It is used in recent versions of
|
|
* DSM software provided by Synology. Nonetheless, some earlier boards
|
|
* were delivered with an older version of u-boot that left internal
|
|
* registers mapped at 0xd0000000. If you have such a device you will
|
|
* not be able to directly boot a kernel based on this Device Tree. In
|
|
* that case, the preferred solution is to update your bootloader (e.g.
|
|
* by upgrading to latest version of DSM, or building a new one and
|
|
* installing it from u-boot prompt) or adjust the Devive Tree
|
|
* (s/0xf1000000/0xd0000000/ in 'ranges' below).
