Since quite some time I activated cpu-freq in the kernel (v3.6) and installed the corresponding cpu-freq tools. It seems that I can clock both my OVEROs as well as the DuoVero at 1 GHz, at least that's what cpu-freq tells me:
$ cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq

When I do benchmarking I can clearly see the performance increasing between 300 MHz (governer: powersave) and 1 GHz (governer: performance) with the same factor of approx. 3.3. Besides it seems to work stable until now, I never had any troubles or crashes in 1 GHz mode. Huray!
Has anybody else already had some experience with using the 1 GHz mode in this setup (Overo/DuoVero @ kernel version 3.6)?

Btw.: I recently discovered a "omap-3.0-abb" branch in your kernel repo, is this already working? Or is it the branch which is still missing those ABB patches from TI?

Be very nice to have some feedback. I know midway through last year that
there were some ABB patches floating about that promised and did not
deliver. Any movement since then?
I am still waiting for working ABB patches from TI . . .
