From 823e7546c4a2bd4c8edce6d8dc8544fd79287c55 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Thu, 10 Jul 2014 10:42:05 +0200 Subject: [PATCH] ARM: ux500: remove pointless cache setup complexity This cleans out non-DT cache setup (the ux500 is DT only), and sinks the l2cc base into the unlock function.
