I'm really not sure about this. The large binary suggests that you have code/data at 0 and at 0xfe000000, which seems wrong. So the image is trying to bridge the gap and ends up being huge. If you have a working image from an old U-Boot and can build it from source, that helps a lot, since you can compare settings, etc. Sorry I can't help more...
