OK, I thought again and talked to some guys. It's okay to add updated to the non-dt board files on exynos4 for now. I know, until there is dt coverage for more drivers, actually it will be difficult to build/support a complete system with only dt support. Note, we need to keep adding more and more support for dt for exynos4 and exynos5. Then only we can stop the development of non-dt board files. Thanks for many opinions about this and if any objections, feel free to contact me. Thanks.
