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.

Some platforms don't have valgrind support, and sometimes you simply might
not want to use valgrind. But at present, dtc, or more specifically its
testsuite, won't compile without valgrind because we use the valgrind
client interface in some places to improve our testing and suppress false
positives.
This adds some Makefile detection to correctly handle the case where
valgrind is not available.

At present we have a build check that python-dev and swig are available.
If they are not, we print a message and skip building pylibfdt.
However this check is not currently present with 'make install'. The
install is attempted, and fails. See crbug.com/789189
Split the check out into a separate script and use it twice, once for the
build and once for the install. This corrects the error.

For adoption into systems that may have additional arguments to be passed into
install(1) upon install, split out INSTALL into the different types of files to
be installed and use them appropriately. This allows, for instance, passing -s
to strip binaries and libs while not botching directory installs or data/script
installations.

The pylibfdt code is written for Python2, not Python3. So, it's safer to
explicitly request Python2 in our scripts and when checking pkg-config.
On Arch Linux at least, there isn't actually a plain "python" link, just
"python2" and "python3", so the current setup won't work at all.
According to https://www.python.org/dev/peps/pep-0394/ using "python2"
should work, and is preferred.
Updating pylibfdt to work with Python3 would be nice, but is a problem for
another day.

The host compiler on MSYS2 and Cygwin does not allow the -fPIC option,
issuing a warning that is treated as an error and stops the build.

At present we require that setup.py is executed from the Makefile, which
sets up various important things like the list of files to build and the
version number.
However many installation systems expect to be able to change to the
directory containing setup.py and run it. This allows them to support (for
example) building/installing for multiple Python versions, varying
installation paths, particular C flags, etc.
The problem in implementing this is that we don't want to duplicate the
information in the Makefile. A common solution (so I am told) is to parse
the Makefile to obtain the required information.
Update the setup.py script to read a few Makefiles when it does not see
the required information in its environment. This allows installation
using:
./pylibfdt/setup.py install

This simple utility allows writing of values into a device tree from the
command line. It aimes to be the opposite of fdtget.
What is it for:
- Updating fdt values when a binary blob already exists
(even though source may be available it might be easier to use this
utility rather than sed, etc.)
- Writing machine-specific fdt values within a build system
To use it, specify the fdt binary file on command line followed by the node
and property to set. Then, provide a list of values to put into that
property. Often there will be just one, but fdtput also supports arrays and
string lists.
fdtput does not try to guess the type of the property based on looking at
the arguments. Instead it always assumes that an integer is provided. To
indicate that you want to write a string, use -ts. You can also provide
hex values with -tx.
The command line arguments are joined together into a single value. For
strings, a nul terminator is placed between each string when it is packed
into the property. To avoid this, pass the string as a single argument.
Usage:
fdtput <options> <dt file> <<node> <property> [<value>...]
Options:
-t <type> Type of data
-v Verbose: display each value decoded from command line
-h Print this help
<type> s=string, i=int, u=unsigned, x=hex
Optional modifier prefix:
hh or b=byte, h=2 byte, l=4 byte (default)
To read from stdin and write to stdout, use - as the file. So you can do:
cat somefile.dtb | fdtput -ts - /node prop "My string value" > newfile.dtb
This commit also adds basic tests to verify the major features.

This simply utility makes it easy for scripts to read values from the device
tree. It is written in C and uses the same libfdt as the rest of the dtc
package.
What is it for:
- Reading fdt values from scripts
- Extracting fdt information within build systems
- Looking at particular values without having to dump the entire tree
To use it, specify the fdt binary file on command line followed by a list of
node, property pairs. The utility then looks up each node, finds the property
and displays the value.
Each value is printed on a new line.
fdtget tries to guess the type of each property based on its contents. This
is not always reliable, so you can use the -t option to force fdtget to decode
the value as a string, or byte, etc.
To read from stdin, use - as the file.
Usage:
fdtget <options> <dt file> [<node> <property>]...
Options:
-t <type> Type of data
-h Print this help
<type> s=string, i=int, u=unsigned, x=hex
Optional modifier prefix:
hh or b=byte, h=2 byte, l=4 byte (default)

The freetype package already installs a binary named "ftdump", so the dtc
package conflicts with that. So rename the newer dtc tool to "fdtdump".

fdtdump: [F]lat [D]evice [T]ree [dump]

The libfdt shared library is only installed by its unversioned name.
Including it properly in a distribution requires installation of both
the versioned name (used in the binary-only package) and the unversioned
name (used in the development package). The latter is just a symbolic
link, so you need to change the soname in turn to include the version.
While at it, use Makefile variables to shorten some lines and avoid
cut-and-paste typos; and clean up remnants of when shared libraries were
not supported on Darwin.

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).

We are almost clean already with the -Wredundant-decls warning. The
only exception is a declaration for isatty() inside the flex-generated
code. This can be removed by using flex's "never-interactive" option,
which we probably should be using anyway, since we never parse
interactively in the sense that this option implies.

This patch turns on a bunch of extra gcc warnings, most of which are
probably a good idea. Of the new warnings -Wnested-externs and
-Wstrict-prototypes need no code changes, we're already warning-clean.
The remaining one, -Wmissing-prototypes requires trivial changes in
some of the tests (making functions local).
This patch also rearranges the warnings flags into a separate make
variable for convenience, and turns on -Werror, to really encourage
people to keep the code warning-clean.
