So I go for the simple one and agree with Alexey's idea.When dealing with a whole device tree you have to know about the various dynamically generated nodes and props, and handle each appropriately.The code I am changing fetches the device tree and build an fdt. What is that special knowledge in this context you are talking about?
Things like /options are dynamically generated. I thought you would just be able to reuse some FDT parsing code to implement my suggested new interface. Maybe that was too optimistic. Segher
