2011-08-04Convert ISO-8859 files to UTF-8Albert ARIBAUD
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>
2011-07-25autostart: unify duplicated logic into the bootm codeMike Frysinger
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.

2011-01-11Revert "boot cmds: convert to getenv_yesno() with autostart"Wolfgang Denk
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. Signed-off-by: Wolfgang Denk <wd@denx.de>
2010-11-28boot cmds: convert to getenv_yesno() with autostartMike Frysinger
Use the new helper func to clean up duplicate logic handling of the autostart env var. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2010-11-28do_bootm: unify duplicate prototypesMike Frysinger
The duplication of the do_bootm prototype has gotten out of hand, and they're pretty much all outdated (wrt constness).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>
2010-07-24cmd_usage(): simplify return code handlingWolfgang Denk
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. Signed-off-by: Wolfgang Denk <wd@denx.de>
2010-07-04Make sure that argv[] argument pointers are not modified.Wolfgang Denk
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) { ...

2009-06-12General help message cleanupWolfgang Denk
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>
2009-01-28Command usage cleanupPeter Tyser
Remove command name from all command "usage" fields and update common/command.c to display "name - usage" instead of just "usage". Also remove newlines from command usage fields. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>

2007-07-04common/cmd_[a-f]* : Augment CONFIG_COMMANDS tests with defined(CONFIG_CMD_*).Jon Loeliger
This is a compatibility step that allows both the older form and the new form to co-exist for a while until the older can be removed entirely. All transformations are of the form: Before: #if (CONFIG_COMMANDS & CFG_CMD_AUTOSCRIPT) After: #if (CONFIG_COMMANDS & CFG_CMD_AUTOSCRIPT) || defined(CONFIG_CMD_AUTOSCRIPT) Signed-off-by: Jon Loeliger <jdl@freescale.com>
