Hi,
I am sending across patch series to support CPU identification
and run-time silicon revision check for OMAP2/3.
Regards,
Girish

Sorry, I guess the previous patch series might have got auto wrapped. Resending the patch series without auto wrapping.

Is there any way to identify at runtime a speed sorted omap vs a
standard one?
Then some of the code we have for N800/N810 could be moved from board to
arch.

I don't believe that information is encoded anywhere today for 2420 which is sufficient for your needs. The 1.4v DM addendum does show an external marking difference.
You probably could pass this information up from your boot loader as an ATAG. Or rely on say the Menelaus root voltage level to let the system know. You also surly tie it to some N8xx board attribute. All N810's have it and all rev2 N800's have it or something.
The only OMAP chip way today would probably rely on maintenance of large tables leveraging production specific information scattered here and there. Of which is mostly not documented today. And these tables would be ever growing.
