[U-Boot-Users] [PATCH] Add Vitesse 8601 support to TSEC driver

["André Schwarz" <Andre.Schwarz@matrix-vision.de>]

Tor,

what a pitty - I've been working on this for 2 days now.
I did not implement the skew since I configured it by hardware strapping.

Very interesting PHY : low power, self calibrating ...... and cheap :-)

Is yor PHY already up and running including data ?

regards,
Andr? Schwarz
