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.
