This one was a bit of a judgement call. You are absolutely correct in what you say that Kirkwood supports two, but to the best of my knowledge, no one has yet implemented a board using both busses (I am not that familiar with OpenRD, I may have to eat my words). For the sheevaplug, guruplug & dreamplug, it is definitely the case that only one device can be attached. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
