[U-Boot-Users] u-boot on ixdp425

I have just ran the u-boot on ixdp425 dev board (thanks to all the friends on this list that have supported me) and now i'm trying to write a device driver to use the internal eth interface of ixp425 to allow the tftp boot of linux image. Before starting I would like to know if anybody has already written such driver (i don't want to re-invent the wheel!).

Any idea?

many thanks
