The problem with SYSRAM_NS is that it might be also used in other code, not related to firmware only. I don't know exactly all the use cases for it. Is it really a big problem or we could let it be for now, merge the patches for firmware and then convert SYSRAM_NS to dynamic mapping when its situation clarifies?
