Couple months ago I posted patches that add a full-featured Trusted Foundations support on Tegra30 [0] (including suspend-resume, thumb2 kernel, handling CONFIG_CACHE_L2X0=n), unfortunately they didn't get any attention yet. Could you please take a look and try out [0]? I've got everything working without touching arch/arm/mm/cache-l2x0* at all. Would be awesome if we could cooperate the efforts somehow, maybe that will also help to get more attention from the maintainers.
