Are you absolutely sure that the exynos3250 IP is the same as the s3c6410 (I don't know much about the exynos family). The concern being that if at one point you have an errata on one or ther other, you will have to break the DT ABI by undoing this change. Note that I'm fine with it, I'm just asking.
