Not all /bin/echo implementations support the -e option. Instead, use
printf, which appears to be more widely available than /bin/echo -e.
See commit eaec1db "fdtget-runtest.sh: Fix failures when /bin/sh isn't
bash" for history.
I have tested this on Ubuntu 10.04 with /bin/sh pointing to both dash
and bash.

Projects such as linux and u-boot run sparse on libfdt. libfdt
contains the notion of endianness via usage of endian conversion
functions such as fdt32_to_cpu. As such, in order to pass endian
checks, libfdt has to annotate its fdt variables such that sparse
can warn when mixing bitwise and regular integers. This patch adds
these new fdtXX_t types and, ifdef __CHECKER__ (a symbol sparse
defines), includes the bitwise annotation.

The previous definition of for_each_*() would always include the very
first object within the list, irrespective of whether it was marked
deleted, since the deleted flag was not checked on the first object,
but only on any "next" object.
Fix for_each_*() to check the deleted flag in the loop body every
iteration to correct this.
Incidentally, this change is why commit 45013d8 dtc: "Add ability to
delete nodes and properties" only caused two "make checkm" failures;
only two tests actually use multiple labels on the same property or
node. With this current change applied, but commit 317a5d9 "dtc: zero
out new label objects" reverted, "make checkm" fails 29 times; i.e.
for every test that uses any labels at all.

The device tree language as currently defined conflicts with the C pre-
processor in one aspect - when a property or node name begins with a #
character, a pre-processor would attempt to interpret it as a directive,
fail, and most likely error out.
This change allows a property/node name to be prefixed with \. This
prevents a pre-processor from seeing # as the first non-whitespace
character on the line, and hence prevents the conflict. \ was previously
an illegal character in property/node names, so this change is
backwards compatible. The \ is stripped from the name during parsing
by dtc.

Currently each of the semantic checks in checks.c has a "level" between

This patch reworks the code to instead have separate boolean flags for
warning and error. At present having both flags set will have the same

When merging one device tree over the top of a previous tree, it is
possible to define a duplicate label that has the same name and points
to the same property or node. This is currently allowed by the duplicate

capability is maintained.

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.

In device trees in the world, properties consisting of a single 64-bit
integer are not as common as those consisting of a single 32-bit, cell
sized integer, but they're common enough that they're worth including
convenience functions for.
This patch adds helper wrappers of fdt_setprop_inplace(), fdt_setprop() and
fdt_appendprop() for handling 64-bit integer quantities in properties. For
better consistency with the names of these new *_u64() functions we also
add *_u32() functions as alternative names for the existing *_cell()
functions handling 32-bit integers.

Outputing to stderr is best avoided unless there is an error or warning to
display. At present dtc always displays the name of the file it is compiling
and the input/output formats. For example:
DTC: dts->dts on file "-"
This can cause problems in some build systems. For example, U-Boot shows
build errors for any boards which use dtc at present. It is typically the
only message output during such a build. The C compiler does not output
anything in general. The current dtc behaviour makes it difficult to
provide a silent build in the normal case where nothing went wrong.
Remove the message entirely.

On Ubuntu, /bin/sh is dash (at least by default), and dash's echo doesn't
accept the -e option. This means that fdtget-runtest.sh's EXPECT file will
contain "-e foo" rather than just "foo", which causes a test failure.
To work around this, run /bin/echo instead of (builtin) echo, which has
more chance of supporting the -e option.
Another possible fix is to change all the #! lines to /bin/bash rather
than /bin/sh, and change run_tests.sh to invoke sub-scripts using $SHELL
instead of just "sh". However, that would require bash specifically, which
may not be desirable.

It is often inconvenient to place device tree files in the same directory
as their includes, or to specify the full path to include files.
An example of this is in U-Boot where we have a .dtsi file for each SOC
type, and this is included by the board .dts file. We need to either use
a mechanism like:
/include/ ARCH_CPU_DTS
with sed or cpp to perform the replacement with the correct path, or
we must specify the full path in the file:
/include/ "../../arch/arm/dts/tegra20.dtsi"
The first option is not desirable since it requires anyone compiling the
file to first pre-process it. The second is not desirable since it
introduces a path which is project-specific into a file which is supposed
to be a hardware description. For example Linux and U-Boot are unlikely to
put these include files in the same place.
It is much more convenient to specify the search patch on the command line
as is done with C pre-processors, for example.
Introduce a -i option to add to the list of search paths used to find
source and include files.
We cannot use -I as it is already in use. Other suggestions welcome.

Currently run_tests.sh generates several files of text test data. The
procedure it uses for this is somewhat torturous and has several problems:
* Since the test data is derived from a dts file, a cursory glance at the
test output suggests something is wrong with the processing of that dts.
This is misleading since in fact it's just being used as an arbirary
string.
* Since the base input has linefeeds removed, the head and sort commands
used later have no effect.
* Although an attempt is made to get rid of characters which the shell
will mangle, it's not thorough enough. Specifically it leaves in \ which
means that some string escapes found in the input data can get expanded
somewhere along the line in some shells.
This patch, therefore, replaces this generation of test data with a
pre-canned "Lorem ipsum" of approximately 2k. On my system, where /bin/sh
is dash, this fixes a test failure due to the aforementioned string
escapes being evaluated on one but not the other of the two comparison
paths (I haven't tracked down exactly where the expansion is happening).

Currently the fdt{get,put}-runtest.sh scripts invoke diff to check if
fdt{get,put} did the right thing. This isn't great though: it's not
obvious from the diff output which is the expected and which is the
actual result; diff's line by line behaviour is useless here, since all
the results are a single line and finally, when there is a difference
it always prints information even when the tests are supposed to be
running in quiet mode.
This patch uses cmp instead, and explicitly prints the expected results,
when running in verbose mode (the invocation of fdtget itself will have
already displayed the actual results in this mode.

This patch cleans up how the fdtget and fdtput tests are invoked.
Specifically we no longer hide the full command lines with a wrapper
function - this makes it possible to distinguish fdtget from similar
fdtput tests and makes it easier to work out how to manually invoke an
individual failing test.
In addition, we remove the testing for errors from the
fdt{get,put}-runtest.sh script, instead using an internal wrapper
analagous to run_wrap_test which can test for any program invocation
that's expected to return an error.
For a couple of the fdtput tests this would result in printing out
ludicrously large command lines. Therefore we introduce a new
mechanism to cut those down to something reasonable.
