commit 2c9e2db72197d8b2d5bcbeaf02b381542e7495d7
Author: Solomon Peachy <pizza@shaftnet.org>

    xduoox3:  More bootloader updates
    
     * Rework the LCD initialization a bit
     * Power off after 5 seconds if we hit a fatal error
     * Turn on verbose output if PLAY is held down on powerup
     * Minor code style cleanups
    
    The goal is to not perform the LCD init unless it's needed; ie
    only if we run into an error or enter USB mode.
