From e8ec653c767f56346eb1fadbc07e0706d6dbd56f Mon Sep 17 00:00:00 2001 From: Hauke Mehrtens Date: Thu, 14 May 2015 00:38:28 +0200 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.
