That's the plan, yes. This will take some time though. To make this work
we'll need bindings devices which are normally autoprobable (MMC, USB).
UBI would need a binding. We'll need bindings for DOS/GPT partitions.
I expect some opposition there...
At least for USB bindings already exist that just have to be
implemented.
