You would need to consider other SoC - Exynos5250/5250/5410/5420/5433 because other have different rotation limitations like below, Exynos5250 Maximum size : 2048x2048 for Tile Mode or Rotation Exynos5410/5420 Maximum size : 2016x2016 for Tile mode or Rotation In case of Exynos5433, it seems more complicated. Refer to Chapter 45.5.4 Size Constraints of TRM document.
