Is that actually the case? I can't find any current support in the kernel for running on these SH4 cores, and I was under the impression that they were being phased out, if not already gone. And the bulk of the driver-related discussion I've seen on linux-sh over the past year does not seem to be related to hardware that's present/usable on boards where you can run Linux/SH. If this is incorrect, I'd like to hear some views on how/why such hardware is relevant to arch/sh. Rich
