Thanks for your work. You can send the v7 so we will have a look at the
overall driver; but since we raised the DMA buffers issue we had a
discussion with Boris about how to handle them and I think we are going
to adopt the same solution as Wolfram in the I2C subsystem: manual
flagging. Sadly, this is probably the best we can do to ensure proper
DMA support.

There is nothing set is stone yet but I started a small rework to
handle MTD operations differently (and add a DMA_SAFE flag), you can
have a look there [1]. Don't base your work on it for now as it is just
a preliminary version, subject to big changes.
