I think we need to order the work:

 - get your use struct file as bdev handle series in
 - rebase the above series on top of that, including some bigger changes
   like block2mtd which can then use normal file read/write APIs
 - rebase what is left of this series on top of that, and hopefully not
   much of this patch and a lot less of patch 1 will be left at that
   point.
