From 7705dd256ce363f8b01429efb2f0dc4d1ee23c89 Mon Sep 17 00:00:00 2001 From: Russell King Date: Fri, 15 May 2015 11:07:14 +0100 Subject: [PATCH 71/74] ARM: l2c: write auxiliary control register first Before calling the controller specific configuration function, write the auxiliary control register first, so that bits shared with other registers (such as the prefetch control register) are not overwritten by the later write to the auxctrl register.
