Hi Florian
There is a general trend of making ops structures const. It closes off
kernel exploits. This coping and then modifying prevents us making
ds->ops a pointer to a const.
You are already using b53_common.c as a library. Could you go further
with the concept, and export the ops you need for SF2, and have SF2
define its own ops structure? We can then swap to const ops dsa wide.
Thanks
Andrew
