So what I suggest for now is:

- I welcome all patches moving the clearly barebox specific stuff to
  separate files, like Sebastian already started.
- Use plain Linux Kernel dts files where possible. I will try and deny
  all changes to these files except "sync to Linux-x.y"
- Leave the i.MX dts files how they are until the changes currently
  queued in Linux-next hit mainline.
