U-boot assumes that all FMAN ports have a PHY. Some SoCs (like T1040) have fixed links. This means that the ports are connected MAC to MAc and there is no Ethernet PHY attatched. This patch initializes a FMAN MAC even if it doesn't have a PHY attached.

Some Freescale SoCs like T1020 and T1040 have an integrated L2 Switch. The L2 Switch ports may be connected to Ethernet PHYs over SGMII and QSGMII.

This patch adds a driver for VSC9953 L2 Switch. This Vitesse IP is integrated in Freescale T1040 and T1020 SoCs. The L2 switch has 10 Ethernet ports: 2 internal fixed-links (ports 8 and 9) at 2.5 Gbps and and 8 external ports at 1 Gbps. The external ports may be connected to PHYs over QSGMII and SGMII.

Commands have also been added to enable/disable a port and to check a port's link speed, duplexity and status. The commands are:

ethsw port <port_nr> enable|disable - enable/disable an l2 switch port ethsw port <port_nr> show - show an l2 switch port's configuration

port_nr=0..9; use "all" for all ports

For more detailse please see doc/README.t1040-l2switch

Freescale's T1040qds board may be configured to have up to 5 FMAN ports (FM1@DTSEC1 to FM1@DTSEC5). From these 5 ports, 2 of them may be fixed-links (FM1@DTSEC1 annd FM1@DTSEC2), connected to other two ports from an intergrated VSC9953 L2 Switch (switch ports 8 and 9). These fixed-link ports have no PHYs attatched, so they don't have a corresponding MDIO.
