Yes. i.e. the only way forward is multiplatform _only_. _BUT_ you can choose to disable all other platforms in a kernel, and thus turn it into a single-platform build. That's fine. What we don't want is added logic like the EXYNOS_SINGLE Kconfig was, just to do that. > What I think you mean is that you want the individual EXYNOS versions > to be separate Kconfig options, so you can build a kernel that supports > EXYNOS4 but not EXYNOS5 if you want to.

I'm also OK with that, but please don't make it more granular than per family if you can avoid it. > Note that if you enable LPAE, you will still only be able to build EXYNOS5 > after the patch, but then you can have it in the same kernel as e.g. > Tegra4 and Snapdragon 600. Yep, and that's as expected. -Olof -- To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
