From: Linus Walleij Date: Mon, 27 Jul 2015 20:40:53 +0000 (+0200) Subject: ARM: nomadik: move l2x0 setup to device tree X-Git-Tag: firefly_0821_release~176^2~1186^2~7 X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=98badfd31ccb1448866b99cb6a64ad227d141d22;p=firefly-linux-kernel-4.4.55.git 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.
