[U-Boot] [PATCH V2 0/9] rely on latest dtc, simplify

[Stephen Warren]

From: Stephen Warren <swarren at nvidia.com>

This is a series of patches which simplifies the rules to build *.dts in
U-Boot by relying on features in the latest dtc. The include rules are
made more consistent between cpp (when processing *.dts) and dtc. The cpp
flags are made more consistent with the way the kernel processes *.dts to
allow better portability of *.dts between the two.

I'm sending V2 now that dtc-1.4.0 has been tagged/released, and hence
there's a version number that patch 1/9 "Validate dtc is new enough" can
check for. I'll leave it up to you whether this series is applicable for
the current or next release.

Stephen Warren (9):
