I wonder if this patch really is a good idea. We've confirmation from
Allwinner that all of the sun5i SoCs are using the same die. Sure some
peripherals are not connected to the outside but it is still the same
die. This patch feels to me like it just grows the kernel and dts size
without serving any purpose.

Regards,

Hans
