I'll warn that back when I looked at the RPi* kernel support,
the kernel had hard coded various things instead of using
the device tree. (I do not remember the details.) As such,
the kernel would not even notice differences in such areas
to report on needing to be updated when the kernel's code
no longer matched what following the Device Tree would do.

In other words, I'd not be surprised if just updating
u-boot proves insufficient: kernel development/updating
likely would be required as well.
