* cmd_usage(): simplify return code handlingWolfgang Denk2010-07-24-10/+6
| | | | | | | | | | | | | | | | 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 Denk2010-07-04-12/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Tyser2009-09-22-15/+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.

* Add DNS supportRobin Getz2009-07-22-0/+49
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On 04 Oct 2008 Pieter posted a dns implementation for U-Boot. http://www.mail-archive.com/u-boot-users@lists.sourceforge.net/msg10216.html > > DNS can be enabled by setting CFG_CMD_DNS. After performing a query, > the serverip environment var is updated. > > Probably there are some cosmetic issues with the patch. Unfortunatly I > do not have the time to correct these. So if anybody else likes DNS > support in U-Boot and has the time, feel free to patch it in the main tree. Here it is again - slightly modified & smaller: - update to 2009-06 (Pieter's patch was for U-Boot 1.2.0) - README.dns is added - syntax is changed (now takes a third option, the env var to store the result in) - add a random port() function in net.c - sort Makefile in ./net/Makefile - dns just returns unless a env var is given - run through checkpatch, and clean up style issues - remove packet from stack - cleaned up some comments - failure returns much faster (if server responds, don't wait for timeout) - use built in functions (memcpy) rather than byte copy.

* General help message cleanupWolfgang Denk2009-06-12-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* net: Fix download command parsingPeter Tyser2008-12-04-8/+12
| | | | | | | | | | | | | | | | When CONFIG_SYS_HUSH_PARSER is defined network download commands with 1 argument in the format 'tftp "/path/file"' do not work as expected. The hush command parser strips the quotes from "/path/file" which causes the network commands to interpret "/path/file" as an address instead of the intended filename. The previous check for a leading quote in netboot_common() was replaced with a check which ensures only valid numbers are treated as addresses.

* [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>
