Add fdtget utility to read property values from a device tree 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) Signed-off-by: Simon Glass <sjg@chromium.org>

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.

fdtget-runtest.sh: use printf instead of /bin/echo -e 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.

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.

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.
