    dtc: Add code to make diffing trees easier · 37c0b6a0
    David Gibson authored
    This patch adds a "dtdiff" script to do a useful form diff of two
    device trees.  This automatically converts the tree to dts form (if
    it's not already) and uses a new "-s" option in dtc to "sort" the
    tree.  That is, it sorts the reserve entries, it sorts the properties
    within each node by name, and it sorts nodes by name within their
    parent.
    
    This gives a pretty sensible diff between the trees, which will ignore
    semantically null internal rearrangements (directly diffing the dts
    files can give a lot of noise due to the order changes).
