I notice in last nights merge of the Samsung stuff, this has become
less trivial - it's now:
        /* set sw_reset function */
        if (soc_is_exynos4210() || soc_is_exynos4212() || soc_is_exynos4412())
                s5p_reset_hook = exynos4_sw_reset;

So which of the boards should be converted and which shouldn't ?
In other words, which exynos4210, 4212 or 4412 platforms?
