+1 I'm of the opinion that we support DT only platforms for multi-platform but this is based on the approach of only caring for multi-platform for newer systems and not worrying too much for legacy HW. I look at this from the perspective of how much return do we get on investing effort into making it possible for every platform to be built as part of consolidated zImage. I don't expect distros (the main users of a single zImage IMHO) to spend many cycles on older platforms and those of us who still have some of them sitting around to use are generally developers who are going to be doing a lot of builds anyways... ~Deepak _______________________________________________ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev
