No. Every SoC is effectively unique in all aspects. There is no common physical memory layout, no common interrupt controller, no common timer, etc. The base addresses for everything is also SoC specific, so it's a catch-22 situation - you need to know what the SoC is to be able to find out where various registers and memory is located. _______________________________________________ devicetree-discuss mailing list [email protected] https://lists.ozlabs.org/listinfo/devicetree-discuss
