Subject: [RESEND PATCH 0/6] This series adds SMP support for the MediaTek MT6580.

This patchset adds support SMP on MediaTek MT6580 Cortex-A7 qual core SoC.

This is based on v4.1-rc1 and following patch series:
(1) Yingjoe Chen's "Add SMP bringup support for mt65xx socs" [1]
(2) Mars Cheng's "Add mt6580 basic chip support" [2]
(3) Sascha Hauer's "Mediatek SCPSYS power domain support" [3]

The secondary cores are power off as default on MT6580, this change adds
a new enable-method to turn on power to the cores during booting process.

The System Power Manager (SPM) inside the SCPSYS is for the CPU MTCMOS
power domain control. Please check [3] for more information about SCPSYS.
