+ #address-cells = <1>;

+ smem@fa00000 {This should be smem@fc428000 matching the first reg property. It's weird though, because if smem is using a secondary region it will be under the SoC node and have a reg property. Otherwise it would be directly under the root node and only have a memory-region. It would be nice if we could somehow move the rpm message ram (0xfc428000) into the reserved-memory node so that we could use memory-region for both regions.
