Changes since U-Boot 1.1.1:
======================================================================
* Fix minor network problem on MPC5200: need some delay between
resetting the PHY and sending the first packet. Implemented in a
"natural" way by invoking the PHY reset and initialization code
only once after power on vs. each time the interface is brought up.
* Add some limited support for low-speed devices to SL811 USB controller
(at least "usb reset" now passes successfully and "usb info" displays
correct information)
