From 7705dd256ce363f8b01429efb2f0dc4d1ee23c89 Mon Sep 17 00:00:00 2001

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.
