I can't help you with that exact board, but I've written an "ethernet
over PCI" driver for Linux and U-Boot. The Linux driver has been posted
here on linuxppc-dev and on the lkml. Search for "net: add PCINet
driver" and you'll find it.
It won't work on your board, but it should serve as a good example about
how to communicate over PCI.
You are the third user asking for something like this recently. :) Too
bad the mainline kernel developers seem to be mostly ignoring the
driver I wrote.
Definitely get PCI/PCI-E working and stable before you try to start
communicating between the devices, though.
