Hi!

I'm using the v3.8.x branch from RCN with a BBB clone based on am3352 with
800MHz factory rate. I can see that under heavy load the frequency goes up
to 1GHz while it should be limited to 800MHz. Can anybody suggest a way to
limit the frequency in the kernel?

I did some testing and setting the cpu frequency with the below command
does limit it.  Using sysfsutils and editing /etc/sysfs.conf to include
these lines:

devices/system/cpu/cpu0/cpufreq/scaling_governor = ondemand

devices/system/cpu/cpu0/cpufreq/scaling_max_freq = 600000

sets the frequency at bootup.  However the cpu still runs at 1GHz for a few
seconds before these settings take effect, so I think we need a kernel
change to fix this
