drivers/qe/uec_phy.c: Added PHY-less (fixed PHY) driver.
Copied over the fixed PHY driver as used in pp4xx/4xx_enet.c. This adds support for PHY-less MAC connections to the UEC. Signed-off-by: Richard Retanubun <RichardRetanubun@RuggedCom.com> Signed-off-by: Ben Warren <biggerbadderben@gmail.com>utp

/*
|
||||||
|
* 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 CONFIG_PHY_ADDR equal to CONFIG_FIXED_PHY and
|
||||||
|
* then define CONFIG_SYS_FIXED_PHY_PORTS to define what the speed and
|
||||||
|
* duplex should be for these ports in the board configuration
|
||||||
|
* file.
|
||||||
|
*
|
||||||
|
* For Example:
|
||||||
|
* #define CONFIG_FIXED_PHY 0xFFFFFFFF
|
||||||
|
*
|
||||||
|
* #define CONFIG_PHY_ADDR CONFIG_FIXED_PHY
|
||||||
|
* #define CONFIG_PHY1_ADDR 1
|
||||||
|
* #define CONFIG_PHY2_ADDR CONFIG_FIXED_PHY
|
||||||
|
* #define CONFIG_PHY3_ADDR 3
|
||||||
|
*
|
||||||
|
* #define CONFIG_SYS_FIXED_PHY_PORT(devnum,speed,duplex) \
|
||||||
|
* {devnum, speed, duplex},
|
||||||
|
*
|
||||||
|
* #define CONFIG_SYS_FIXED_PHY_PORTS \
|
||||||
|
* CONFIG_SYS_FIXED_PHY_PORT(0,SPEED_100,DUPLEX_FULL) \
|
||||||
|
* CONFIG_SYS_FIXED_PHY_PORT(2,SPEED_100,DUPLEX_HALF)
