From 2e192b245ed36a63bab0ef576999a95e23f60ecd Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sun, 17 Jan 2016 20:53:52 -0700 Subject: Remove the cmd_ prefix from command files Now that they are in their own directory, we can remove this prefix. This makes it easier to find a file since the prefix does not get in the way.
