Not related to this series, but to the platform in general. You still need to resolved the boot/cpu-method for this platform before you add support for all the 4 cpus on this platform. I remember discussing about CPUIdle on a separate thread. I thought this is best thread to remind that so that it is addressed before we see either cpuidle or cpuhotplug support on this platform. -- Regards, Sudeep
