The existing Exynos 32-bit platform support needs to be realigned in order to support newer 64-bit Exynos platforms. The driver model will be utlized for drivers on the 64-bit Exynos platforms and so some of the older platform support code would not be required for the newer 64-bit Exynos platforms.

I think it's better to split to new architecture type for 64bit exynos platform - ARCH_EXYNOS64? What do you think?
I was infact thinking to avoid adding a new ARCH type as much as possible and reuse ARCH_EXYNOS for 64-bit as well. Eventually, the code in mach-exynos has to move into respective driver folders (atleast for ARM64 platforms) and have as little as possible in mach-exynos directory.
I understood what you want. But I think, we can reuse mach-exynos code even if we make new ARCH type. And the cpu type should have a dependency with ARCH, not boards. I don't believe that we should add a cpu type to every boards. Please consider again.
Ok, I understand your point. There is one more approach without adding a new ARCH_EXYNOS64. This will be posted in the next version of the patch. I hope that would resolve the concern here.
Thanks, Thomas.
Thanks, Minkyu Kang.
