From looking at other *.dtsi files I understand one would have to
include the armada-370-xp-u-boot.dtsi in armada-370-xp.dtsi in order to
move the U-Boot-specific properties out. I guess one should then do this
for other boards too. I am not sure if I am confortable with touching
all these boards. Maybe one should do this the next time when syncing
the DTS files with Linux.

If it is OK for you, for this patch, I would simply introduce a
armada-xp-synology-ds414-u-boot.dtsi as Chris suggested.

Cheers,
Ezra.
