* 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).

* For that reason, it is strongly advised not to
