+ * Some boards do not have a PHY for each ethernet port. These ports are known
+ * as Fixed PHY (or PHY-less) ports. For such ports, set the appropriate
+ * CONFIG_SYS_UECx_PHY_ADDR equal to CONFIG_FIXED_PHY_ADDR (an unused address)
+ * When the drver tries to identify the PHYs, CONFIG_FIXED_PHY will be returned
+ * and the driver will search CONFIG_SYS_FIXED_PHY_PORTS to find what network
+ * speed and duplex should be for the port.
+ *
+ * Example board header configuration file:
+ * #define CONFIG_FIXED_PHY 0xFFFFFFFF
+ * #define CONFIG_SYS_FIXED_PHY_ADDR 0x1E (pick an unused phy address)
+ *
+ * #define CONFIG_SYS_UEC1_PHY_ADDR CONFIG_SYS_FIXED_PHY_ADDR
+ * #define CONFIG_SYS_UEC2_PHY_ADDR 0x02
+ * #define CONFIG_SYS_UEC3_PHY_ADDR CONFIG_SYS_FIXED_PHY_ADDR
+ * #define CONFIG_SYS_UEC4_PHY_ADDR 0x04
+ *
+ * #define CONFIG_SYS_FIXED_PHY_PORT(name,speed,duplex) \
