[U-Boot] [PATCH v3 00/11] Add driver for VSC9953 Ethernet Switch

[Codrin Ciubotariu]

This patches add support for VSC9953, a Vitesse L2 Switch IP which is integrated in the T1040/T1020 Freescale SoCs.

About Device:
=============
The Seville Gigabit Ethernet switch core contains eight 10/100/1000 Mbps Ethernet ports and two 10/100/1000/2500 Mbps ports. It provides a rich set of Ethernet switching features such as advanced TCAM-based VLAN and QoS processing as well as security processing using a TCAM.

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 at DTSEC1 and FM1 at 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

=> ethsw port all show
    Port   Status     Link    Speed   Duplex
       0  enabled     down       10     half
       1  enabled     down       10     half
       2  enabled     down       10     half
       3  enabled       up     1000     full
       4 disabled     down        -     half
       5 disabled     down        -     half
       6 disabled     down        -     half
       7 disabled     down        -     half
       8  enabled       up     2500     full
       9  enabled       up     2500     full
=>

Changes for v2:
	- split the bug fix from the implementation of
		SerDes protocols of L2 Switch ports patch;
	- added debug messages if MDIO reads or writes timeout;
	- added debug messages when reset of VSC9953 switch fails;
	- replaced Copyright and license to the generic one;
	- added patch descriptions;

Changes for v3:
	- replaced the arrays type from 'int' to 'u8' int the
		 fix for mapping of Freescale SerDes protocols;
	- removed "Change-id" lines from almost all the patches;
