I'm currently looking for ways to slightly reduce image size to convert this board to DM_VIDEO. Yesterday I've submitted two patches for video uclass, this is still not enough to be able to build the board with DM_VIDEO enabled. I'm currently trying to drop dead or useless code from mxc_ipuv3 driver and also tried to remove device tree nodes for stuff not used in U-Boot. This might give us a few kilobytes of image size reduction and DM_VIDEO could probably work (at least when using gcc-8.1). But I'm expecting new bloat when next merge window opens and new patches will be merged, this board will fail again. Moving the environment would help a lot. -- Anatolij
