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

+This file contains information for VSC9953, a Vitesse L2 Switch IP
+which is integrated in the T1040/T1020 Freescale SoCs.
+
+About Device:
+=============
+VSC9953 is an 8-port Gigabit Ethernet switch supports the following features:
+       -       8192 MAC addresses
+       -       Static Address provisioning
+       -       Dynamic learning of MAC addresses and aging
+       -       4096 VLANs
+       -       Independent and shared VLAN learning (IVL, SVL)
+       -       Policing with storm control and MC/BC protection
+       -       IPv4 and IPv6 multicast
+       -       Jumbo frames (9.6 KB)
+       -       Access Control List
+       -       VLAN editing, translation and remarking
+       -       RMON counters per port
+
+Switch interfaces:
+       -       8 Gigabit switch ports (ports 0 to 7) are external and are connected to external PHYs
+       -       2 switch ports (ports 8 and 9) of 2.5 G are connected (fixed links)
+               to FMan ports (FM1@DTSEC1 and FM1@DTSEC2)
+
+Commands Overview:
+=============
+Commands supported
+       - enable/disable a port
+       - check a port's link speed, duplexity and status.
+
+Commands syntax
+       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
