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.
Please add a dtc-version Makefile variable and corresponding tools/dtc-version.sh script, ala gcc/binutils so that we can error out gracefully if dtc isn't supporting the options we need.
For clarity, we need some sort of graceful error-out, be it version check or flag-is-supported check. I fear this is going to lead to a lot of people not being able to compile and I'd like to be able to give a clear error message.
