So that address has changed between two SoC revisions? That's
unfortunate, to say the least. I'm most probably using an early revision
of the hardware (EVT0?), as it doesn't even support MCT.

I'm afraid :( and I agree secondary CPU should work on all of
Exynos4210. But I'm still think about the method...

What about the following patch?

Uhm...this is really hack but I'd like to use another normal way...?

Oh, no question about the hack status. The trouble is, unless there is a
sure way to tell which SoC revision we're running on, there's little
else we can do than poke both locations and pray.

Is there such a way to identify the SoC revision?

It's also required for OneNAND. as you know C210 EVT0 OneNAND DMA has
bug and need to workaround.

platform codes should provide the these function. please see the OMAP
codes. how to handle it.

So we know there's a need beyond the wish to see the second core up and
running on my board.

Now what is the proper method to detect the revision of the SOC?
Handling it is no problem, once we have the information. Unfortunately
the documentation I have is less than helpful on that subject.
