We don't have any DT support for S3C and S5P upstream yet, so I would certainly agree on that. I think we should plan at least one release of supporting both simultaneously in order to find bugs with the DT implementation before we can consider removing ATAGS support for any major platform. However, I also really want to see all ARMv6 and ARMv7 platforms get moved over to use ARCH_MULTIPLATFORM, and it probably makes sense to eventually move over all platforms that support ARCH_MULTIPLATFORM to be DT-only. I hope we do both for EXYNOS in 3.10, and then do at least MULTIPLATFORM support for S5P* in 3.11, possibly also for S3C64xx, in order to convert all ARMv6 and ARMv7 platforms to MULTIPLATFORM. For the ARMv5 platforms (S3C24xx and others), we can be much more flexible with the timing, plus we can keep S3C and S5P in a state where they are DT-only in multiplatform configurations but allow ATAGS when configured as standalone like we do today, at least for a couple of releases after introducing multiplatform support, until we are comfortable with the DT support and don't break any working platforms.
