     During tests performed in internal development trees, the
     BogoMIPS calculations @ 1GHz wouldn't go beyond "830-850"
     range. While there was no such inconsistency on OMAP3EVM.
There are some other reasons to avoid GPTIMER12 when possible, which you 
should probably put in the patch description.  The most important, in my 
view, is that the clock source for GPTIMER12 is much less frequency-stable 
than the clock sources for GPTIMER1.  So using GPTIMER12 can result in 
major time skew over a fairly short interval.

I've been meaning to send a patch like this for some time, so I'm happy to 
see this fixed.
