    dts/Makefile: simplify dtc invocation · cc4f427b
    Stephen Warren authored
    The invocation of dtc is significantly more complex that it could be,
    in order to work around an issue on old versions of dtc, which print
    a message to stdout every time they run.
    Remove this workaround, on the assumption that people have or will
    upgrade to a newer version of dtc. This simplifies the build rule
    Related, split the invocation of cpp and dtc into separate commands
    rather than a pipeline, so that if either fail, it is detected. This has
    the nice benefit of saving off the result of the pre-processing step,
    allowing it to be easily inspected.
    Assuming a new enough dtc (which an earlier patch enforces), dtc will
    parse #line directives in its input file, and generate correct file and
    line numbers in error messages, even though cpp is unconditionally
    applied to its input file.
