I did wonder about doing that for this patch and the sdhci one. It'd also cut down the Cc spam. > Reviewed-by: Andrew Lunn <andrew@lunn.ch> > > Andrew

The 98DX2530 SoC is similar to the Armada 3700 except it needs a different MBUS window configuration. Add a new compatible string to identify this device and the required MBUS window configuration.
