Ultimately my goal is to communicate between them via pci-e (is > there anything out there that does this already?). 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. Ira
