sunxi: Move SPL s_init() code to board_init_f()
The current sunxi implementation uses gdata, which is going away. It also
sets up DRAM before board_init_f() in SPL.
There is really no reason to do much in s_init() since board_init_f() is
called immediately afterwards. The only change is that we need our own
implementation of board_init_f() which sets up DRAM before the BSS (which
is in DRAM) is cleared.
The s_init() code runs once for SPL and again for U-Boot proper. We
shouldn't need to init the clock/timer/gpio/i2c init twice, so just have it
in SPL.

net/vsc9953: Add driver for Vitesse VSC9953 L2 Switch IP
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
net/fm: Enable FMAN ports if l2switch ports are connected over SGMII
If SerDes is configured to connect L2 Switch ports from T1040
over SGMII or QSGMII, the two FMAN fixed ports (FM1@DTSEC1 and FM2@DTSEC2)
that are connected to two L2 swtch ports must be enabled. These
ports don't have PHYs and must be treated accordingly.
arch/powerpc: Fix mapping of Freescale SerDes protocols
The number of supported serdes protocols on Freescale SoCs
has increased over time. Until now, an u64 variable have been
initialized on boot with the configured protocols. However,
since this number has increased (enum srds_prtcl has more
than 64 values), 64 bits are no longer sufficient to hold track
of all the configured protocols.
This patch replaces the u64 map values with static arrays.
To keep track of the number of serdes protocols, the
SERDES_PRCTL_COUNT vale has been added at the end of
enum srds_prtcl. This value must always be the last one.
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.
