Please also list the interrupt, even though we don't use it yet.
The manual says it's 127 - 32 = 95.

I'm worried about the representation here.
In the user manuals, the SAT is shown as part of the BE.
Look at it this way: if it did come before the BE and is
independent, we shouldn't have to bring the SAT out of
reset for simplefb to work.
For comparison, a similar function unit called "CMU" found on
the other post-sun6i SoCs has the same function description as
SAT on the A33. It uses the reserved registers at the beginning
of the BE address space.

Put this node above soc@? Properly sorted that is.
Everything else looks good.
