Ok, so I've managed to get write a patch for this myself, currently it
only sets the dtb filename for the bananapi, I will add to all the
other boards tomorrow and then submit it upstream, in the mean time
you can find it here:

https://github.com/jwrdegoede/u-boot-sunxi/commits/next

The last commit there is a slightly cleaned-up version of your:
"automatically add console= to bootline when not existing"

patch, I would also like to submit that one upstream, may I add
your (Dennis)' Signed-off-by to it ?

Regards,

Hans
