2014-06-11common/cli_hush.c: remove unnecessary double bracesJeroen Hofstee
Clang interpretes an if condition like "if ((a = b) == NULL) as it tries to assign a value in a statement. Hence if you do "if ((something)) it warns you that you might be confused. Hence drop the double braces for plane if statements. Simon Glass <sjg@chromium.org> Signed-off-by: Jeroen Hofstee <jeroen@myspectrum.nl>
2014-06-05Fix hush to give the correct return code for a simple commandSimon Glass
When a simple command like 'false' is provided, hush should return the result of that command. However, hush only does this if the FLAG_EXIT_FROM_LOOP flag is provided. Without this flag, hush will happily execute the empty string command immediate after 'false' and then return a success code. This behaviour does not seem very useful, and requiring the flag also seems wrong, since it means that hush will execute only the first command in a sequence. Add a check for empty string and fall out of the loop in that case. That at least fixes the simple command case. This is a change in behaviour but it is unlikely that the old behaviour would be considered correct in any case.

2014-05-29Rename bootretry functions and remove #ifdefsSimon Glass
Add a bootretry_ prefix to these two functions, and remove the need for the #ifdef around everything (it moves to the Makefile). Signed-off-by: Simon Glass <sjg@chromium.org>
2014-05-29Move bootretry code into bootretry.c and clean upSimon Glass
This code is only used by one board, so it seems a shame to clutter up the readline code with it. Move it into its own file. Signed-off-by: Simon Glass <sjg@chromium.org>
2014-05-29Add cli_ prefix to readline functionsSimon Glass
This makes it clear where the code resides. Signed-off-by: Simon Glass <sjg@chromium.org>
2014-05-29move CLI prototypes to cli.h and add commentsSimon Glass
Move the CLI prototypes from common.h to cli.h as part of an effort to reduce the size of common.h. Signed-off-by: Simon Glass <sjg@chromium.org>
2014-05-29Rename hush to cli_hushSimon Glass
Hush is a command-line interpreter, so rename it to make that clearer. Signed-off-by: Simon Glass <sjg@chromium.org>
