The kernel usual is willing to accept such things as long as the code is reasonable. You are telling me you add a linker section for cpu_ops just for "a platform that exists", sorry I do not believe that (and that's *not* reasonable). I do not like this line of reasoning, at all, because you were aware of PSCI and ignored it, deliberately. Start by pushing code for platforms upstream that support PSCI, "they are coming up next" does not cut it. I can see power management mach code coming next, just no way. Implement PSCI and the kernel will be willing to accept it, as it stands as far as I am concerned that's a NAK on the series.
