Sorry, the DT is just a platform description, it can be added later.
What is sorely missing is the hardware support for A10, some of which
was already added previously, some of it is rotting in the 01-arria10
branch and some of it (DDR controller support) is missing altogether.

So what I'd like to see is a patchset that makes the A10 support usable,
such that I can use mainline U-Boot on the A10 devkit without any
additional out-of-tree stuff. I am not interested in picking separate
bits and pieces which in itself are only dead weight.
