- * Fixed PHY (PHY-less) support for Ethernet Ports.

- * Copied from arch/powerpc/cpu/ppc4xx/4xx_enet.c
- *--------------------------------------------------------------------
- *
- * Some boards do not have a PHY for each ethernet port. These ports are known
- * as Fixed PHY (or PHY-less) ports. For such ports, set the appropriate
- * CFG_SYS_UECx_PHY_ADDR equal to CONFIG_FIXED_PHY_ADDR (an unused address)
- * When the drver tries to identify the PHYs, CONFIG_FIXED_PHY will be returned
- * and the driver will search CONFIG_SYS_FIXED_PHY_PORTS to find what network
- * speed and duplex should be for the port.
- *
- * Example board header configuration file:
- * #define CONFIG_FIXED_PHY 0xFFFFFFFF
- * #define CONFIG_SYS_FIXED_PHY_ADDR 0x1E (pick an unused phy address)
- *
- * #define CFG_SYS_UEC1_PHY_ADDR CONFIG_SYS_FIXED_PHY_ADDR
- * #define CFG_SYS_UEC2_PHY_ADDR 0x02
- * #define CFG_SYS_UEC3_PHY_ADDR CONFIG_SYS_FIXED_PHY_ADDR
- * #define CFG_SYS_UEC4_PHY_ADDR 0x04
- *
- * #define CONFIG_SYS_FIXED_PHY_PORT(name,speed,duplex) \
- * {name, speed, duplex},
- *
- * #define CONFIG_SYS_FIXED_PHY_PORTS \
