If i remember correctly, we discussed this when the contribution was
made. I think the stock firmware might use this for applying updates.
Maybe Benoit can comment?
If so, removing this will break compatibility with stock firmware. Do
we want to do that? There are a few other mvebu dts files with a
partition spanning the whole flash. Should we remove them as well?
