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