Add 'license' command to U-Boot command line The 'license' command includes the U-Boot license (GPLv2) into the actual bootloader binary. The license text can be shown interactively at the U-Boot commandline. For products where the commandline can actually be accessed by the end user, this helps to prevent inadvertent GPL violations, since the GPLv2 license text can no longer be 'forgotten' to be included into the product. The 'license' command can be enabled by CONFIG_CMD_LICENSE. Signed-off-by: Harald Welte <laforge@openmoko.org>

Make sure that argv[] argument pointers are not modified. 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) { ...

various cmd_* files: fixed layout a little bit Most of the files have U_BOOT_CMD on a separate line, but a few didn't and had the first line on the same line as U_BOOT_CMD. This changes these files by adding a line break and a tab Signed-off-by: Frans Meulenbroeks <fransmeulenbroeks@gmail.com>

General help message cleanup 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>
