Default MMU-500 reset operation disables context caching in

Replace default MMU-500 reset operation with Qualcomm specific reset
operation which envelope the default reset operation and re-enables
context caching in prefetch buffer for Qualcomm SoCs.

an issue.. definitely not the case!


Noted, will send v6 by removing the Suggested by tag
and will address the return check as well.

Thanks,
