Subject: [PATCH] omap3beagle: register SD interface
Thanks for updating it. I've pushed it now, but I had to apply some
parts manually because of recent changes. Can you please check it
got applied OK?
I compiled an booted latest git and see this:

I suspect it's somewhere in i2c, but I have no proof for that. Any
quick guesses what might be causing this?
Can you try if reverting following helps?

That doesn't seem to make a difference.
regards,
Koen
