From aa8d3bb177a3ba64407d98c75d5c6c5130ff2182 Mon Sep 17 00:00:00 2001 From: Magnus Damm Date: Wed, 13 Feb 2013 22:46:38 +0900 Subject: [PATCH] ARM: shmobile: Kill off sh73a0 scu_base_addr() function Replace scu_base_addr() with a static shmobile_scu_base variable and introduce SH73A0_SCU_BASE. Later in the series the shmobile_scu_base variable will be made into a global variable so this is preparation only.
