Hi, this series add the support to load FIT image supplied devicetree overlays. The v1 of this series can be found here [1]. The overlay loading wasn't coupled to bootm due to the following reasons: - 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). - Loading a single overlay takes ~20ms (depending on the overlay size) if the same FIT image is used to supply the kernel, initrd, devicetree and devicetree-overlays. This is an improvement compared to the v1 of this series which required ~1sec.
