The overlay loading wasn't coupled to bootm due to the following reasons: - Users can add their own overlay filter - By making use of the common overlay handling we can specifiy a different/separate FIT image which provides only overlays. - It should be possible to apply FIT image overlay to the barebox live-tree (not implemented yet).
