From 188237e28d7fece0471640ba86f6d8cd164ed085 Mon Sep 17 00:00:00 2001 From: Saeed Bishara Date: Wed, 2 Jul 2008 06:06:32 -1100 Subject: [ARM] Feroceon: don't disable BPU on boot On Feroceon platforms that have a branch prediction unit, bit 11 of the cp15 control register controls the BPU. This patch keeps the old value of this bit instead of always clearing it.
