In addition to an example DTS patch (probably to warp itself), could you briefly write up a binding and put it in Documentation/powerpc/dts-bindings/amcc (or similar)? Also please CC the devicetree-discuss list on that part.
Here is a start at the doc. I have sent it as a patch, but could just as easily send raw text. The example comes from the warp dts, just with less partitions, so I have not included a warp dts patch here. Cheers, Sean
