Hmm...above change and adding definition of EXYNOS_PA_S_MDMA1 address can fix the problem you commented on EXYNOS4210 Rev0 without others?...The problem is affecting only EXYNOS4210 Rev0 and the fix is applied only for case when soc_is_exynos4210() && samsung_rev() == EXYNOS4210_REV_0, or did you mean something else?
Yeah, I know. I mean just adding secure mdma1 address is enough for exynos4210 rev0. 8<-----
