CONFIG_COMMANDS
Most monitor functions can be selected (or
de-selected) by adjusting the definition of
CONFIG_COMMANDS; to select individual functions,
#define CONFIG_COMMANDS by "OR"ing any of the
following values:
Monitor commands can be included or excluded
from the build by using the #include files
"config_cmd_all.h" and #undef'ing unwanted
commands, or using "config_cmd_default.h"
and augmenting with additional #define's
for wanted commands.
#define enables commands:

If you don't define CONFIG_COMMANDS it defaults to
CONFIG_CMD_DFL in include/cmd_confdefs.h. A board can
override the default settings in the respective
include file.
EXAMPLE: If you want all functions except of network
support you can write:
#define CONFIG_COMMANDS (CFG_CMD_ALL & ~CFG_CMD_NET)
#include "config_cmd_all.h"
#undef CONFIG_CMD_NET
