That is where they came from.  Since the u-boot libfdt is a subset of
the whole dtc.git repository (just the libfdt part), I've been cherry
picking only the libfdt/* patches (with the help of others).

I see David has another patch for the libfdt library that I probably
should pick up so that we stay in sync (18 lines of code by counting
semicolons).

    libfdt: Add helper function to create a trivial, empty tree

    The libfdt read/write functions are now usable enough that it's become a
    moderately common pattern to use them to build and manipulate a device
    tree from scratch.  For example, we do so ourself in our rw_tree1
testcase,
    and qemu is starting to use this model when building device trees
for some
    targets such as e500.

    However, the read/write functions require some sort of valid tree to
begin
    with, so this necessitates either having a trivial canned dtb to
begin with
    or, more commonly, creating an empty tree using the serial-write
functions
    first.

    This patch adds a helper function which uses the serial-write
functions to
    create a trivial, empty but complete and valid tree in a supplied
buffer,
    ready for manipulation with the read/write functions.
