From 9a2c33a422d60e8e55c5aff6752522dc39993b16 Mon Sep 17 00:00:00 2001 From: Russell King Date: Mon, 7 Jul 2014 13:53:03 +0100 Subject: [PATCH] ARM: l2c: fix revision checking The revision checking in l2c310_enable() was not correct; we were masking the part number rather than the revision number. Fix this to use the correct macro.
