Adds support for ethernet networking on the da830evm platform. This platform uses an SoC EMAC interface and a 3 port ethernet switch as a PHY with an RMII interface. The PHY also has a i2c interface for configuring the switch functions. Signed-off-by: Nick Thompson <nick.thompson@ge.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>
