- Subject: [PATCH 3/3] ARM: BCM5301X: activate some additional options in pl310
- cache controller
- In the default Broadcom SDK the shared override is activated for this
- cache controller, do the same in the upstream code. Data and
- instruction prefetching is not activated by default for this cache
- controller on the bcm53xx SoC, do it manually like it is done in the
- vendor SDK.
