One question: do you know if anyone is working on support for the newer Exynos chips, or the Nexell S5P6818 series? It seems odd that none of the chips from the past three years are supported yet.

Indeed it looks like the pace for new chips has slowed down. The Nexell series are similar to Exynos but this is different company so probably they would end up in different sub-arch. Only some IP blocks are similar to Exynos even though the datasheet has Samsung marks. I saw patches for U-Boot (I do not remember the author) so maybe soon something will happen on LKML. Best regards, Krzysztof

When I looked at an old 32-bit 3.4 kernel tree, I could see no similarity to Exynos, but it seems that there is now an active development tree for a 64-bit 4.x kernel for the Samsung Artik board series, just no patches.
