From 94796d8544d4248028141bad11c6a74b840e9d6e Mon Sep 17 00:00:00 2001 From: Wolfgang Denk Date: Sun, 24 May 2009 19:17:29 +0200 Subject: Make "usage" messages more helpful. In case of incorrect command invocations U-Boot used to print pretty useless "usage" messages, for example: => nand markbad Usage: nand - NAND sub-system In the result, the user would have to run the "help" command to get the (available) information about correct command usage. Change this, so that this information gets always printed. Note that this changes the user interface of all commands, but hopefully to the better.
