From ba9279519b371340e01cadf4c230e9d52a4bf8c4 Mon Sep 17 00:00:00 2001 From: Catalin Marinas Date: Fri, 18 Apr 2008 22:43:17 +0100 Subject: [PATCH] Allow the L2X0 outer cache support to be configurable By default, this option was selected by the platform Kconfig. This patch adds "depends on" to L2X0 so that it can be enabled/disabled manually.
