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.
