Basically I'd like to keep the ARCH_EXYNOS4 and ARCH_EXYNOS5 it can be a
duplicated line though. Because it is a different core.

Looks good, ok, the description of Cortex-A9 and Cortex-A15 will be added.

Yes. I think at least one SoC should be selected when one ARCH_ is selected.
And as you know, now ARCH_EXYNOS5 is used only for EXYNOS5250 SoC.

Now that would be better if could keep less headers.
