Hmm, I thought I addressed these: >> --- a/include/config_cmd_defaults.h >> +++ b/include/config_cmd_defaults.h > > updating these files is not sufficient and will break boards. drop the hunks to > these files and update include/config_defaults.h instead. The "mkconfig" program automatically includes both config_defaults.h and config_cmd_defaults.h, so this is sufficient to not break boards. This is exactly how CONFIG_CMD_GO works. Since it's always on, there's no need to add it to config_cmd_all.h either (which is why I removed that hunk). > would be a good time to split this into a dedicated common/cmd_reset.c, > we can also then fix cmd_boot.c to only build when CONFIG_CMD_GO is enabled The only references to CONFIG_CMD_GO are in config_cmd_defaults.h, README, and common/cmd_boot.c, there is nothing that ever turns it off, so perhaps the config symbol should just be removed? Cheers, Kyle Moffett

This new #define is set in config_cmd_defaults.h (which is automatically included on every board by "mkconfig"), but this allows boards to elect to omit the "reset" command if necessary with "#undef CONFIG_CMD_RESET".
