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>
