YAML encoded DT is useful for validation of DTs using binding schemas.
The YAML encoding is an intermediate format used for validation and
is therefore subject to change as needed. The YAML output is dependent
on DTS input with type information preserved.

This is missing at present and the fdtput tool could use a litle more
information than just its help text.
This might be useful for distributions which want to provide a man page.

This is missing at present and the fdtget tool is no-longer trivial. Add
a little bit of information.

Since libfdt support overlay application on FDT blobs, provide
a command line tool that applies an arbitrary number of
overlays, one after another to a base fdt blob and output
the result in the given file.

This patch enable the generation of symbols & local fixup information
for trees compiled with the -@ (--symbols) option.
Using this patch labels in the tree and their users emit information
in __symbols__ and __local_fixups__ nodes.
The __fixups__ node make possible the dynamic resolution of phandle
references which are present in the plugin tree but lie in the
tree that are applying the overlay against.

The freetype package already installs a binary named "ftdump", so the dtc
package conflicts with that. So rename the newer dtc tool to "fdtdump".
This even makes a bit more sense:
ftdump: [F]lat device [T]ree [dump]
fdtdump: [F]lat [D]evice [T]ree [dump]

Updated a jdl.com URL reference.
Generalized the new section IV to be "Utility Tools"
and added a small blurb about ftdump as well.

This large patch removes all trailing whitespace from dtc (including
libfdt, the testsuite and documentation). It also removes a handful
of redundant blank lines (at the end of functions, or when there are
two blank lines together for no particular reason).
As well as anything else, this means that quilt won't whinge when I go
to convert the whole of libfdt into a patch to apply to the kernel.

This is the new location for technical descriptions of the DTC.
Derived from the kernel's Documentation/powerpc/booting-without-of.txt.
The booting-without-of.txt that was here was very old and out of date.
