My (dev) board unfortunately, have a bootloader which can't boot over
serial. Could you elaborate that a bit more? Why is this required for
uart boot? kwboot will talk with the bootrom why does u-boot need
anything? Or will there just be no output until the uart is initialized?

Is this new? AFAIK only <boardname>-u-boot.dtsi is included
automatically.
