One more minor comment about the order of the flags for OMAP4.

Since this code is generated by script, the flags are sorted by name.
HWMOD_16BIT_REG should then be the first one. This is of course 
applicable for the 4 instances.
I already updated the generator to take the sysconfig register width 
into account.

Thanks,
