I'm not sure that you understand my intention.

You want to introduce:
board/samsung/common/board.c - with only Exynos5 code

I mean that it should looks like this, e.g:
"board/samsung/common/board_exynos4.c" - common code for all Exynos 4
"board/samsung/common/board_exynos5.c" - common code for all Exynos 5
since there is some duplicated code in Exynos4 boards that can be moved 
to one common file in the future.
Do you understand my intention now?
