* Move console definitions into a new console.h fileSimon Glass2015-11-19-0/+1
| | | | | | | | The console includes a global variable and several functions that are only used by a small subset of U-Boot files. Before adding more functions, move the definitions into their own header file. Signed-off-by: Simon Glass <sjg@chromium.org>
* Add cli_ prefix to readline functionsSimon Glass2014-05-29-10/+10
| | | | | | This makes it clear where the code resides. Signed-off-by: Simon Glass <sjg@chromium.org>
* move CLI prototypes to cli.h and add commentsSimon Glass2014-05-29-0/+1
| | | | | | | 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>

* common: move extern char console_buffer[] to common.hIgor Grinberg2011-11-22-1/+0
| | | | | | | | | Extract all extern declarations for console_buffer[] out of c files into the common.h header. Signed-off-by: Igor Grinberg <grinberg@compulab.co.il> Cc: Frank Gottschling <fgottschling@eltec.de> Cc: Murray Jensen <Murray.Jensen@csiro.au>
* cmd_usage(): simplify return code handlingWolfgang Denk2010-07-24-4/+2
| | | | | | | | | | | | | | | | 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 Denk2010-07-04-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Denk2009-06-12-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* Command usage cleanupPeter Tyser2009-01-28-1/+1
| | | | | | | | 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>
