* 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.

* Convert ISO-8859 files to UTF-8Albert ARIBAUD2011-08-04-1/+1
| | | | | | | | There was a mix of UTF-8 and ISO-8859 files in the U-Boot source tree, which could cause issues with the patchwork review system. This commit converts all ISO-8859 files to UTF-8. Signed-off-by: Albert ARIBAUD <albert.u.boot@aribaud.net>
* autostart: unify duplicated logic into the bootm codeMike Frysinger2011-07-25-10/+1
| | | | | | | | | | | Rather than having a bunch of random commands handle autostart behavior, unify the logic in a single place. This also fixes building of these different commands when bootm is disabled.

* Revert "boot cmds: convert to getenv_yesno() with autostart"Wolfgang Denk2011-01-11-1/+1
| | | | | | | | | | This reverts commit 5a442c0addc69d0c4b58e98e5aec1cf07576debb. This commit changed the behaviour of getenv_yesno() (both the default behaviour and the documented behaviour for abbreviated arguments) which resulted in problems in several areas.

* boot cmds: convert to getenv_yesno() with autostartMike Frysinger2010-11-28-1/+1
| | | | | | | Use the new helper func to clean up duplicate logic handling of the autostart env var. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* do_bootm: unify duplicate prototypesMike Frysinger2010-11-28-1/+0
| | | | | | | | The duplication of the do_bootm prototype has gotten out of hand, and they're pretty much all outdated (wrt constness). Unify them all in command.h. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* cmd_usage(): simplify return code handlingWolfgang Denk2010-07-24-2/+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 Denk2010-07-04-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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) { ...

* General help message cleanupWolfgang Denk2009-06-12-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
