Hi,

CONFIG_MCPM and CONFIG_ARM_CCI are optional features that won't be used
unless explicitly enabled in the device tree. CONFIG_BIG_LITTLE is not
enabled in the new defconfig at all (I also believe that it is optional
or at least can be made optional).

Therefore please modify existing exynos_defconfig to support EXYNOS5410
instead of adding the new defconfig. Having the common defconfig is really
important from the long-term maintainance POV.

Best regards,
