[PATCH] ARM: exynos: print CPU id on probe

[PATCH] ARM: exynos: print CPU id on probe

[Olof Johansson]

It's useful to get the CPU ID/rev printed during boot sometimes, so
add a line with that information. Given that the fields have moved
within the register over time, don't try to be clever and parse it --
just print the raw values for now.

Kukjin, please apply if you're OK with this. Thanks!

Yes, why not? I'll apply, I have small concerns for exynos5800 though ;)

Thanks,

That it reports identical to 5422? That's hardly our problem. :-)
