I have a slightly different approach in my queue that uses
scripts/ubinize-image.sh which allows using per device block- and
pagesizes, and control whether the kernel should be included on a per
device basis. E.g. the Netgear R7500 has the kernel raw on the flash,
so the kernel should not be included there. I plan to push it today,
if that approach is okay with you.

I also have a buildstep for wrapping the ubi in a itb file so
qsdk-sysupgrade accepts it, but when I did this it seemed to flashed
correctly, and u-boot was able to load the kenrel, but openwrt then
failed to mount the on flash ubi. Unfortunately I forgot to backup the
original firmware, so I will need to free up some space for qsdk to
reproduce it. Sysupgrade from within OpenWrt is working fine though.
