Each SoC has specification.For example voltage or ids current. These values are related to production process. If you have a good specification SoC, you can supply lower voltage into SoC. Also, If your SoC has bad specification, you have to supply higher voltage into SoC. So, after get these SoC specification value on initialize time, we can use these value to fix voltage for running SoC. Using by this patch set, Exynos4210 can get SoC specification and adjust voltage.
