This is fine. Do we have secure devices here ?
If so, we should take care of setting the domains permissions for avoiding prefetch aborts. As it was done for OMAP using arm_init_domains. So that function and the above should be executed on am33xx as well.
Thanks to Lokesh for reminding this.
Yes, but I can't easily test them. I'll see if arm_init_domains just works on non-HS devices (I know I had a failure pulling all the OMAP4 code over, but didn't try hard, just looked again at the "easy" path).
