[Aggarwal, Anuj] It's kind of a "tuck" sound coming in the end, after 1 or  2 seconds.

[Aggarwal, Anuj] No, it is not. Reason being we already have beagle & 
sdp3430 there, which are both similar to omap3evm, which I pushed. 
So mine got rejected. We had some discussions on how to handle this
scenario but nothing got finalized.

[Aggarwal, Anuj] Yes, it comes in both the cases.
