From 0b52b2508b1e410c2e80408a580412d85401ecd3 Mon Sep 17 00:00:00 2001 From: Magnus Damm Date: Fri, 9 Jan 2015 14:08:49 +0100 Subject: [PATCH] ARM: shmobile: sh73a0: Introduce generic setup callback Add a generic sh73a0 machine setup callback for the upcoming sh73a0 multiplatform case. Cache needs to be configured, and legacy clocks must be omitted.
