From: Karlheinz Jerg karlheinz.jerg@keymile.com
kmvect1 has a UEC2 connection to the piggy board and a UEC0 connection to the switch MV88E6122. This switch has a connection to a frontport ethernet interface. The ethernet port used for network booting is automatically selected by u-boot. If a Piggy is plugged, the Piggy port is selected (UEC2, eth1). If the Piggy isn't present, the Frontport is selected (UEC0, eth0).
The switch reset is connected to a GPIO on the PRIO3 board FPGA (GPIO28) and released at startup.
