in repository device-tree-compiler.

commit 8eaf5e358366017aa2e846c5038d1aa19958314e
Author: Jon Loeliger <jdl at freescale.com>
Date:   Tue Nov 20 09:14:03 2007 -0600

    Add a script that compares an "old" and "new" dtc results.
    
    Lots of room for improvement here.  Command line options, etc.
    The script iterates over a hard-coded list of kernel DTS files.
