Subject: [PATCH] ARM: sun7i: Add Cubieboard2 Device Tree

The Cubieboard2 is the successor of the first Cubieboard, and shares the
same hardware, except that the Allwinner A10 found initially has been
replaced by an Allwinner A20.

Hi,

This patch depends on the v3 of the patchset "ARM: sunxi: Introduce Allwinner A20
support" I sent previously.
