This needs to be rebased on top of master as there's a lot of config.h
things that should be in the defconfig.

[U-Boot] [PATCH 14/14] mips: jz47xx: Add Creator CI20 platform

[Marek Vasut]

From: Paul Burton 

Add support for the Creator CI20 platform based on the JZ4780 SoC.
The DTS file comes from Linux 4.6 as of revision
78800558d104e003f9ae92e0107f1de39cf9de9f

So far, there are still a few details which will have to be fixed
once they are fleshed out in Linux:
- pinmux: Thus far, this board just pokes the pinmux registers to
  set the pinmux. For MMC in SPL, this will have to stay.
  But for full u-boot a proper pinmux driver will have to
  be added once the pinmux semantics in DT are in mainline
  Linux.
- ethernet,efuse: DT bindings are missing from mainline Linux.
