a) add DT node for SW1 as Enter button The SW1 button can be used as a simple one-button keyboard and is connected to PD17. Note: SW1 has a second meaning to change the boot sequence when pressed while powering on. b) give eth0_power a defined voltage. This is a 3.3V power switch (DVNET3.3V). Signed-off-by: H.
