Did you look at the RTL?

I'm not sure it's that simple.  For example PWRSTCTRL/PWRSTST offsets are 
handled very differently between AM335x and the other OMAPs.  Also the 
LOGICRETSTATE mask bits are different.  These unnecessary deltas suggest 
to me that the underlying hardware implementation is different.

I spent some time a few years ago trying to find some hardware guy to give 
some straight answers about the implementation history for the underlying 
blocks, but was never able to find that person.
