Hook these platforms restart code into the new restart hook rather
than using arch_reset().

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?

except the arch/arm/mach-exynos4/mach-smdk4x12.c, exynos4210 is used.
currently all exynos4 series has same reset function. it's preparation
for exynos5 series maybe.

you can use the exynos4_sw_reset for all boards.

Thanks, Kyungmin.

Thanks, that gets me back to where I was with the patch before the
exynos4 move.

Thanks.

Best regards,
Kgene.
