+    - #address-cells : Address representation for "rapidio" devices.
+      This field represents the number of cells needed to represent
+      the RapidIO address of the registers.  For supporting more than
+      32-bits RapidIO address, this field should be <2>.
+      See 1) above for more details on defining #address-cells.

What does the RapidIO standard say about number of address
bits?  You want to follow that, so all RapidIO devices can
use the same #address-cells, not just the FSL ones.  Also,
are there different kinds of address spaces on the bus, or
is it just one big memory-like space?
