How different are the DTBs provided by different firmware releases?

Could we run into problems because some elder or newer firmware releases
are not supported by U-Boot? - This prospect is what makes your patch a
bit scary to me.

Which different firmware releases did you test against?

Do you plan to keep the existing defconfigs and dtbs?
