From e7bd34a15b85655f24d1b45edbe3bdfebf9d027e Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Tue, 31 Jul 2007 17:07:28 +0900 Subject: sh: Support explicit L1 cache disabling. This reworks the cache mode configuration in Kconfig, and allows for explicit selection of write-back/write-through/off configurations. All of the cache flushing routines are optimized away for the off case.
