   4 Subject: [PATCH 3/3] ARM: BCM5301X: activate some additional options in pl310
   5  cache controller
   6
   7 In the default Broadcom SDK the shared override is activated for this
   8 cache controller, do the same in the upstream code. Data and
   9 instruction prefetching is not activated by default for this cache
  10 controller on the bcm53xx SoC, do it manually like it is done in the
  11 vendor SDK.
