[U-Boot] [U-Boot PATCH v2 10/12] keystone2: net: add keystone ethernet driver

Murali Karicheri
2014-02-20T17:55:12Z

From: Vitaly Andrianov <vitalya@ti.com>

Ethernet driver configures the CPSW, SGMI and Phy and uses
the the Navigator APIs. The driver supports 4 Ethernet ports and
can work with only one port at a time.

Port configurations are defined in board.c.
