[PATCH 1/4] ARM: shmobile: sh73a0: Introduce generic setup callback
Geert Uytterhoeven

Fri Jan 9 05:08:49 PST 2015
From: Magnus Damm <damm+renesas at opensource.se>
Add a generic sh73a0 machine setup callback for the upcoming
sh73a0 multiplatform case. Cache needs to be configured, and
legacy clocks must be omitted.
