Yes, we are using am3517evm file for AM33XX MACHINE_INIT definition here.
These patches have been reviewed and accepted in the list, only thing is
they couldn't make it to upstream during v3.4 merge window.

I believe Tony is going to push them for v3.5 now.

I maintain multiple branches along with one superset branch in
my gitorious tree, for example, currently I have,

Individual features branches:
----------------------------
32ksync-timer-cleanup : 32k timer cleanup
am335x-baseport-for-tony : baseport patches (reviewed & accepted)
am335x-prm-cm-hwmod : prm/cm/hwmod patches

superset branch:
---------------
am335x-upstream-staging: 

I merge all feature branches into this superset branch and one additional
Patch, required to get beaglebone to boot.

Thanks Paul, really appreciate your help here. I will take a look at this 
and let you know. Also, please let me know if you have any comments in the 
patch.

I really want to target for v3.5 merge window, and atleast get all basic 
prm/cm/clock/hwmod things upstream.


Thanks,
Vaibhav
