I tested your branch. Your commands seem to work. Here is the log:

I noticed this message in the log though:

Booting over qspi does not work. Probably because it is not a dedicated
qspi flash image (does not get flashed with the correct offset).
About some bits getting flipped:
For me it is not just some bits getting flipped. I read back the image
from /dev/mtd0 with the dd command and compare the hexdump ouput to the
original image. Theoretically it should identical, but that is not the
case. There are not just some flipped bits, but the Image flashed via
uuu looks like a completely different image. I also tested flashing with
dd in linux and in U-Boot with loading the image via fatload from the
sdcard and flashing it with "sf update ${loadaddr} 0 ${filesize}". With
those two flashing methods I get an Image that is identical to the
original Image when I read it back, as I would expect.
