While discussing at the U-Boot mailing list about i.MX6Q USB host
support for U-Boot, there was the question what's about the same for
mainline Linux. See below.
I'd like to continue this discussion with a new subject and adding the
Linaro mailing list.

Do you have any pointers to the discussion about this? Hopefully we
could learn from that.

I think the good news is at least that Linaro is working on a more or
less recent kernel (atm 3.2). So, as mentioned above, porting it from
the Linaro kernel to the mainline kernel shouldn't be that hard. The
next step would be to clean them up, hopefully learning from the mx28
experience mentioned above.
What do you think?
