I think I just need to write a new driver from scratch for the new hardware rev. I've also got ehci working for it. I did some pretty ugly stuff in the at91 directory to get it going. I was just hacking to get it working, then I was going to work with Warner to clean up what I had done and get it committed, but both his and my lives got busy and nothing much has happened for 2 months now. But it does sit here on my desk running just fine (and notably not ever crashing or anything). Pretty much I've been using it when I need to see a freebsd 10 manpage, but not much else. :) I heard a rumor that the hardware guys at work are taking a look at using a G45 for an upcoming project. If that happens, that'll ensure a better mci driver gets written. If you need a patchset and are willing to deal with the ugly half-baked nature of what I've got, just let me know. -- Ian
