	Since run_command() and run_command_list() are important and a little confusing, add some basic tests to check that the behaviour is correct. Note: I am not sure that this should be committed, nor where it should go in the source tree. Comments welcome. To run the unit tests use the ut_cmd command available in sandbox: make sandbox_config make ./u-boot -c ut_cmd (To test both hush and built-in parsers, you need to manually change CONFIG_SYS_HUSH_PARSER in include/configs/sandbox.h and build/run again) Signed-off-by: Simon Glass <sjg@chromium.org>
