* Convert cmd_usage() calls in common to use a return valueSimon Glass2012-03-06-1/+1
| | | | | | | | | Change all files in common/ to use CMD_RET_USAGE instead of calling cmd_usage() directly. I'm not completely sure about this patch since the code since impact is small (100 byte or so on ARM) and it might need splitting into smaller patches. But for now here it is.

* cmd_usage(): simplify return code handlingWolfgang Denk2010-07-24-1/+1
| | | | | | | | | | | | | | | | Lots of code use this construct: cmd_usage(cmdtp); return 1; Change cmd_usage() let it return 1 - then we can replace all these ocurrances by return cmd_usage(cmdtp); This fixes a few places with incorrect return code handling, too.

* Make sure that argv[] argument pointers are not modified.Wolfgang Denk2010-07-04-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The hush shell dynamically allocates (and re-allocates) memory for the argument strings in the "char *argv[]" argument vector passed to commands. Any code that modifies these pointers will cause serious corruption of the malloc data structures and crash U-Boot, so make sure the compiler can check that no such modifications are being done by changing the code into "char * const argv[]". This modification is the result of debugging a strange crash caused after adding a new command, which used the following argument processing code which has been working perfectly fine in all Unix systems since version 6 - but not so in U-Boot: int main (int argc, char **argv) { while (--argc > 0 && **++argv == '-') { /* ====> */ while (*++*argv) { switch (**argv) { case 'd': debug++; break; ... default: usage (); } } } ... } The line marked "====>" will corrupt the malloc data structures and usually cause U-Boot to crash when the next command gets executed by the shell. With the modification, the compiler will prevent this with an error: increment of read-only location '*argv' N.B.: The code above can be trivially rewritten like this: while (--argc > 0 && **++argv == '-') { char *arg = *argv; while (*++arg) { switch (*arg) { ...

* Remove deprecated 'autoscr' command/variablesPeter Tyser2009-09-22-18/+0
| | | | | | | | | | | | | | | The more standard 'source' command provides identical functionality to the autoscr command. Environment variable names/values on the MVBC_P, MVBML7, kmeter1, mgcoge, and km8xx boards are updated to no longer refernce 'autoscr'. The 'autoscript' and 'autoscript_uname' environment variables are also removed.

* General help message cleanupWolfgang Denk2009-06-12-8/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many of the help messages were not really helpful; for example, many commands that take no arguments would not print a correct synopsis line, but "No additional help available." which is not exactly wrong, but not helpful either. Commit ``Make "usage" messages more helpful.'' changed this partially. But it also became clear that lots of "Usage" and "Help" messages (fields "usage" and "help" in struct cmd_tbl_s respective) were actually redundant. This patch cleans this up - for example: Before: => help dtt dtt - Digital Thermometer and Thermostat Usage: dtt - Read temperature from digital thermometer and thermostat. After: => help dtt dtt - Read temperature from Digital Thermometer and Thermostat Usage: dtt Signed-off-by: Wolfgang Denk <wd@denx.de>

* Add "source" command; prepare removal of "autoscr" commandWolfgang Denk2009-04-03-3/+4
| | | | | | | | | | | | | | | | | | | | | According to the doc/feature-removal-schedule.txt, the "autoscr" command will be replaced by the "source" command in approximately 6 months from now. This patch prepares this change and starts a 6 month transition period as follows: - The new "source" command has been added, which implements exactly the same functionlaity as the old "autoscr" command before - The old "autoscr" command name is kept as an alias for compatibility - Command sequences, script files atc. have been adapted to use the new "source" command - Related environment variables ("autoscript", "autoscript_uname") have *not* been adapted yet; these will be renamed resp. removed in a separate patch when the support for the "autoscr" command get's finally dropped.

* [new uImage] Add new uImage format support to autoscript routineMarian Balakowicz2008-03-12-2/+9
| | | | | | | | | | | | | | | autoscript() routine is updated to accept second argument, which is only used for FIT images and provides a FIT subimage unit name. autoscript() routine callers must now pass two arguments. For non-interactive use (like in cmd_load.c, cmd_net.c), new environment variable 'autoscript_uname' is introduced and used as a FIT subimage unit name source. autoscript command accepts extended syntax of the addr argument: addr:<subimg_uname> Signed-off-by: Marian Balakowicz <m8@semihalf.com>
