Yes, because the DT language doesn't have a += operator, basically. Some of the MBus ranges are inherently board-specific: when you have a NOR flash, you need a specific MBus range for it. And such a MBus range is board-specific. Since it's not possible to do: ranges = <SoC level ranges> in .dtsi, and: ranges += <board level ranges> in .dts, we simply decided to always put: ranges = <SoC level and board level ranges> in the .dts. It does create some duplication, but that's the best we could do with the existing DT infrastructure.
