The Linksys WRT 3200 ACM (Rango) comes with a 256MiB nand flash chip and different layout. Signed-off-by: Ralph Sennhauser --- Dismissed alternatives: a) Partition layouts as fragments for use with overlay. While the only alternative which might be worth considering it depends on optional overlay support. So should be selected by the target or at least be in the defconfig. Also feels like the mechanism wasn't intended to be used like this. Also bloats the dtbS. b) Adding a separate node for each variant would require to delete the others in the individual dts, just not enabling them isn't enough. c) Use partition layout dtsi which can be included separately. Two more dtsi for now. d) Delete and recreate partitions / nand node for Rango. e) Make partitions child nodes of a partition-layout node to ease defining custom layouts.
