Mainly a common infrastructure so they don't need to hack every driver
to work with their scheme.

But there is no way to escape from the fact that first round will be far
more complicated than just adding their own stuff as-is likely is. Many
of the upstreamed drivers are rewritten and far from their drivers.

And further complicated by their supported designs often using devices
(wifi modules, touch panels, nand chips, etc) where 3 year old barely
maintained vendor code actually works better than what is currently in
the upstream kernel. 

So no, I can not say that there is an easy road ahead,

Henri
