Sorry for the delay, as I mentioned earlier I would like to add the minimum change to avoid this on platforms that don't require this. But that can be done later, I will try to come up with simple solution when I get time. Though I am not 100% happy ;), I am fine with this change for now: Acked-by: Sudeep Holla <sudeep.ho...@arm.com> -- Regards, Sudeep
