[U-Boot] [PATCH v2] net: Add fixed phy driver

[Christian Gmeiner]

This patch is needed if the MAC is directly connected to a ethernet switch.
In my case the FEC MAC is connected to a Micrel KSZ8895. All I need to to
is configure my fixed phy/link like:

#define IMX_FEC_BASE                    ENET_BASE_ADDR
#define CONFIG_FEC_XCV_TYPE             MII100
#define CONFIG_ETHPRIME                 "FEC"
#define CONFIG_FEC_MXC_PHYADDR          0x5
#define CONFIG_PHYLIB
#define CONFIG_PHY_FIXED
#define CONFIG_PHY_FIXED_SPEED		SPEED_100
#define CONFIG_PHY_FIXED_DUPLEX		DUPLEX_FULL
