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.
I've implemented this check and have the patches ready. I'm just waiting for a dtc release that has all the required features, so that there actually is a version number the code can check for.
It sounds like there's agreement to make the dtc release by the end of this week, unless anyone comes forward and objects, and they haven't yet:-)
