Hi Florian,
I've done much the same for Boston already - do these patches work for
you?

Or you could fetch & cherry-pick them from the linux-mti.git repository:
git remote add mti git://git.linux-mips.org/pub/scm/linux-mti.git
git fetch mti
git cherry-pick 75b59b3bddde~7..75b59b3bddde
They apply cleanly to v4.5, hopefully won't need much massaging to apply
to current master. When I get to resubmitting the Boston board support
these patches will be part of it.
Thanks,
Paul
