From db44f1342d8c2606dbbcbcab83741a3d1c872cff Mon Sep 17 00:00:00 2001 From: Hauke Mehrtens Date: Wed, 29 Jul 2015 23:50:59 +0200 Subject: [PATCH] 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.
