Subject: [PATCH 2/5] arch/arm: mioa701 make autoboot of Linux work
Date: Tue, 15 May 2012 23:21:14 +0200	[thread overview]
Message-ID: <1337116877-17657-3-git-send-email-robert.jarzmik@free.fr> (raw)
In-Reply-To: <1337116877-17657-1-git-send-email-robert.jarzmik@free.fr>

Make the autoboot work :
 - if no USB cuable is plugged, continue directly to
   autoboot
 - if an USB cable is plugged, wait for 3 seconds for
   any input on the USB serial gadget, and if none
   happens, continue to autoboot linux kernel
 - else interrupt autoboot and interact on barebox
   console
