[PATCH 27/28] ARM: EXYNOS: Remove CONFIG_SOC_EXYNOS4412

[PATCH 27/28] ARM: EXYNOS: Remove CONFIG_SOC_EXYNOS4412

[Tomasz Figa]

Exynos4212 and Exynos4412 SoCs differ only in number of ARM cores and
there is no need to have separate Kconfig options for them, since they
use the same code.

This patch removes CONFIG_SOC_EXYNOS4412, leaving CONFIG_SOC_EXYNOS4212
as the one supporting both SoCs from this series.

Hmm, how about SOC_EXYNOS4X12 for exynos4212 and exynos4412?

BTW, AFAIK, we need to leave both to support something...I need to check :)

I was thinking about it and finally decided to leave SOC_EXYNOS4212 for 
compatibility reasons - you don't need to change SOC_EXYNOS4212 to 
SOC_EXYNOS4X12 wherever it's used, making it possible to apply some older 
out of tree patches without modification.

OK.

But IMHO, now with DeviceTree, there is usually no need for such level of 
differentiation on config level.

For example we might be even able reduce CPU_EXYNOS4210 and SOC_EXYNOS4212 
to just ARCH_EXYNOS4, because they share almost all the code and all the 
differencies are specified in device tree.

Not for the matter of the change itself, but just for simplicity while
merging when the change is agreed to be good, it is recommended that you
split your changes in different smaller patches, specially because you
are touching several parts of the kernel that belong to different trees.
If one merges your change the way it is, it is likely to create merge
conflicts.
