Holger Hans Peter Freyther 3fd2eddce5 sysmobts-v2: Introduce a recovery command to reflash the system image 
When pressing the reset button on boot the system will enter the
recovery mode, this is done by setting a preboot command. Inside the
preboot command we will sleep and then check if the button is still
pressed, then tftp will be used to download the image and flash it. If
something fails after the DHCP state the network console will be
enabled.
