Hi Sascga,

We had posted new patch set in following link, but still keep our
original framework.

As we mentioned in the new email thread, the SMP operations (smp_boot_secondary)
will be executed before registering the scpsys_drv driver, so the CPUs power
domain is controlled on arch/arm/mach-$(MACHINE) directory. 

Please kindly provide your comments and suggestion. Thank you very much. 

Best Regards,
Scott Shu
