[U-Boot] [PATCH v4 00/30] ARM: k2g: Add support for new K2G ICE EVM.

[Franklin S Cooper Jr]

This patchset adds support for the new Keystone 2 Industrial Communication
Engine board.

This patchset includes the introduction of embedded FIT images in U-boot.
This creates a FIT image of dtb files that enables board specific code to
select which DTB to use at runtime. Initially during boot a generic DTB is
required that enables board detection to occur and once it has can later be
swapped out for the correct dtb.

Version 4 changes:
Rebased on top of master.
Tweaks done to patches 2 and 3 since functions have been added and tweaked
in spl_fit.c.
Left reviewed by as is since changes weren't drastic.

Version 3 changes:
Fixed minor comments that were missed in rev 2.

Version 2 changes:
Some patches were dropped since equivalent changes have already be
incorporated in upstream already.

The addition davinci i2c device model in upstream resulted in some
patches having to be added or tweaked.

The DT for K2G ICE is based on the version that has been accepted into
Linux mainline https://lkml.org/lkml/2017/5/22/28
