Oops, I meant to to do it the other way around since the writethrough
stuff is not yet in mainline, and Russell seems to be ignoring it for
some reason.
I pushed a patch to disable it in the default config.
In addition, I pushed a patch (see below) which will automatically
select writethrough mode if da830 is the only da8xx selected.
BTW, does anyone know if this writethrough issues is solved in the
rev1.1 or rev2.0 spins of the da830?
