fdtput: Remove star from value_len documentation
When clang checks the documentation tags (with -Wdocumentation flag), it
reports the following warning:
fdtput.c:70:11: error: parameter '*value_len' not found in the
function declaration [-Werror,-Wdocumentation]
* @param *value_len Returns length of value encoded
^~~~~~~~~~
fdtput.c:70:11: note: did you mean 'value_len'?
* @param *value_len Returns length of value encoded
^~~~~~~~~~
value_len
As this sounds reasonable, remove the star from the documentation tag.

Fix assorted sparse warnings
This fixes a great many sparse warnings on the fdt and libfdt sources.
These are mostly due to incorrect mixing of endian annotated and native
integer types.
This includes fixing a couple of quasi-bugs where we had endian conversions
the wrong way around (this will have the right effect in practice, but is
certainly conceptually incorrect).
This doesn't make the whole tree sparse clean: there are many warnings in
bison and lex generated code, and there are a handful of other remaining
warnings that are (for now) more trouble than they're worth to fix (and
are not genuine bugs).

fdtput: expand fdt if value does not fit
If you try to insert a new node or extend a property with large value,
using fdtput you will notice that it always fails.
example:
fdtput -v -p -ts ./tst.dtb "/node-1" "property-1" "value-1
Error at 'node-1': FDT_ERR_NOSPACE
or
fdtput -v -c ./tst.dtb "/node-1"
Error at 'node-1': FDT_ERR_NOSPACE
or
fdtput -v -ts ./tst.dtb "/node" "property" "very big value"
Decoding value:
string: 'very big value'
Value size 15
Error at 'property': FDT_ERR_NOSPACE
All these error are returned from libfdt, as the size of the fdt passed
has no space to accomdate these new properties.
This patch adds realloc functions in fdtput to allocate new space in fdt
when it detects a shortage in space for new value or node. With this
patch, fdtput can insert a new node or property or extend a property
with new value greater than original size. Also it packs the final blob
to clean up any extra padding.
Without this patch fdtput tool complains with FDT_ERR_NOSPACE when we
try to add a node/property or extend the value of a property.
Testcases for the new behaviour added by David Gibson.

Add fdtput utility to write property values to a device tree
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.
