u-boot/board/siemens/dxr2/mux.c
Stefan Roese cc07294bc7 arm: am335x: DXR2: Reset SMSC LAN9303 switch via GPIO upon bootup 
Since the switch may be re-configured for VLAN usage in Linux (or any
other OS), lets reset the switch to its default register values upon
power-up. Otherwise network might not be available in U-Boot.
