      Make sure that argv[] argument pointers are not modified. · 54841ab5
      Wolfgang Denk authored
      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 cleanup · a89c33db
      Wolfgang Denk authored
      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

      Add "source" command; prepare removal of "autoscr" command · 74de7aef
      Wolfgang Denk authored
      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.

      Command usage cleanup · 2fb2604d
      Peter Tyser authored
      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.

      Big white-space cleanup. · 53677ef1
      Wolfgang Denk authored
      This commit gets rid of a huge amount of silly white-space issues.
      Especially, all sequences of SPACEs followed by TAB characters get
      removed (unless they appear in print statements).
      
      Also remove all embedded "vim:" and "vi:" statements which hide
      indentation problems.

      [new uImage] Add new uImage format support to autoscript routine · 424c4abd
      Marian Balakowicz authored
      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>

      [new uImage] Add dual format uImage support framework · d5934ad7
      Marian Balakowicz authored
      This patch adds framework for dual format images. Format detection is added
      and the bootm controll flow is updated to include cases for new FIT format
      uImages.
      
      When the legacy (image_header based) format is detected appropriate
      legacy specific handling is invoked. For the new (FIT based) format uImages
      dual boot framework has a minial support, that will only print out a
      corresponding debug messages. Implementation of the FIT specific handling will
      be added in following patches.
