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.
