From 98badfd31ccb1448866b99cb6a64ad227d141d22 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Mon, 27 Jul 2015 22:40:53 +0200 Subject: ARM: nomadik: move l2x0 setup to device tree The cache setup magic value in the Nomadik machine is plain wrong, the correct settings can be done using device tree in accordance with the settings from ST's own port.
