I think the best what you can do is simple disable CONFIG_OF_CONTROL
from mainline u-boot and do not use now.
This is what I do in xilinx tree but OF_CONTROL is also working fine
but needs some setup.

Zybo will be just the same.

In future I want to move this script to be the part of mkimage
but it has low priority now.

yes - but if you use xilinx tree I have also added support for loading
bitstream by SPL. I just haven't sent it to mainline yet.
But you can simple load bitstream in full u-boot which is fully supported
in mainline.

yes - this should also work.

why not? :-)

Simon: Let me know if you need any my help on this.
I have zybo here that I can try it.
