Oh, OK.

BTW, basically the boot should be fine with/without selecting
I2C_EXYNOS5...or if the config is required always for arndale_octa board, it
should be enabled without any manual selecting. I think, it means this is
just temporal solution not right approach to fix the problem..

I need to look at the codes...
