Oh a couple more things...

The fans are controlled via 2 GPIOs on this (see the explanation in the
patch). Do you guys think I should create some kind of pseudo hwmon
device so it can be controlled with one file where you write "off",
"low", "high", or should I just let userspace cope.

Also, it would be nice for said userspace to know the HW revision to be
able to get the right fan control method for example.

Do you have a hook in ARM for adding something to /proc/cpuinfo where I
could export the board revision ? Or a "standard" practice to do that ?

Cheers,
Ben.
