I like to wrap this topic up.
First, any idea why booting from flash does not work for me neither with
uboot or qi?
And second, as it looks like my Qi endeavour was futile, can I use the
following command to go back to uboot?
nandwrite -p /dev/mtd0 $u-boot-image
Or is there some magic that needs to happen?
