Don't use diff to check fdt{get,put} results 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.

Clean up invocation of fdt{get,put} tests 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.

Factor signal checks out of test scripts Several test scripts now have some code to check for a program returning a signal, and reporting a suitable failure. This patch moves this duplicated code into a helper function in tests.sh. At the same time we remove a bashism found in the current copies (using the non portablr $[ ] construct for arithmetic).

Use 'trap' builtin to clean up temporaries in test scripts Some of the test scripts create temporary files, which we remove at the end. Except that we usually forgot to remove them on some exit paths. To avoid this problem in future, this modifies the scripts to use the shell's trap 0 functionality to automatically remove the temporaries on any exit.

Remove unused variable from test scripts Several of the test scripts remove $TMPFILE, without ever having set the TMPFILE variable. This patch fixes it. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>

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. Signed-off-by: Simon Glass <sjg@chromium.org>
