   ARM: EXYNOS: SWRESET is needed to boot secondary CPU on exynos3250 
(2014-10-21 00:06:36 +0900)

----------------------------------------------------------------
Samsung PM updates for v3.19

- Refactor the pm code to use DT based lookup instead of
   using "soc_is_exynosxxxx"

- Firmware supporting suspend and resume to excute of low
   level operations to enter and leave power mode for exynos
   : introduce suspend() and resume() firmware operations

- Fix AFTR mode on boards with secure firmware enabled and
   allows exynos cpuidle driver usage on exynos4x12 SoCs

- Fix build with PM_SLEEP=n and ARM_EXYNOS_CPUIDLE=y

- SWRESET is needed to boot secondary CPU on exynos3250

----------------------------------------------------------------
