drivers/qe/uec_phy.c: Added PHY-less (fixed PHY) driver.
Copied over the fixed PHY driver as used in pp4xx/4xx_enet.c. This adds support for PHY-less MAC connections to the UEC. Signed-off-by: Richard Retanubun <RichardRetanubun@RuggedCom.com> Signed-off-by: Ben Warren <biggerbadderben@gmail.com>

+/*
+ * 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_PHY_ADDR equal to CONFIG_FIXED_PHY and
+ * then define CONFIG_SYS_FIXED_PHY_PORTS to define what the speed and
+ * duplex should be for these ports in the board configuration
+ * file.
+ *
+ * For Example:
+ * #define CONFIG_FIXED_PHY 0xFFFFFFFF
+ *
+ * #define CONFIG_PHY_ADDR CONFIG_FIXED_PHY
+ * #define CONFIG_PHY1_ADDR 1
+ * #define CONFIG_PHY2_ADDR CONFIG_FIXED_PHY
+ * #define CONFIG_PHY3_ADDR 3
+ *
+ * #define CONFIG_SYS_FIXED_PHY_PORT(devnum,speed,duplex) \
+ * {devnum, speed, duplex},
+ *
+ * #define CONFIG_SYS_FIXED_PHY_PORTS \
+ * CONFIG_SYS_FIXED_PHY_PORT(0,SPEED_100,DUPLEX_FULL) \
+ * CONFIG_SYS_FIXED_PHY_PORT(2,SPEED_100,DUPLEX_HALF)
