This overlaps with a submission I made the other day (of usb8388
firmware), sorry for the lack of coordination there.

I don't think the OLPC hardware has any quirks or special features
that mean it requires special firmware.

However, for the usb8388 we do use a special firmware developed by
Cozybit (not Marvell), the one you submitted, which has its own
versioning scheme. The main difference is that it includes mesh
support. I am pretty sure it would run on any usb8388 but OLPC is the
only user of the hardware anyway. See
http://lists.infradead.org/pipermail/libertas-dev/2010-November/003330.html
and the rest of the discussion.

As for sd8686, I thought our firmware was standard, from Marvell, and
simply a newer version of what is in linux-firmware. Do you have
reason to believe otherwise?

Thanks,
Daniel
