Using ubldr requires a u-boot that has the 'API' feature enabled.
Virtually no u-boot comes that way from a vendor.  I don't think the
feature even existed when the kirkwood systems were current.

To enable that, all you need to do is add the CONFIG_API option when
building u-boot.  I'm not sure that's the exact spelling, but look at
the patches that get applied to rpi or beaglebone, it'll be like that.
