Different SoCs so despite how close they look in version numbers, you'd 
expect at a minimum some clock and/or power-domain churn - even if there 
is a 1:1 mapping in register numbers and offsets.

We wouldn't ordinarily expect to be able to be able to move SoC versions 
so easily - 8550 and 8650 have similar SoC version numbers but, this is 
not necessarily an indicator of silicon IP block version reuse.
