From cd217546602dbfe96c3f8e8025eb750fadf1ab4f Mon Sep 17 00:00:00 2001 From: Paul Burton Date: Mon, 24 Mar 2014 10:19:34 +0000 Subject: [PATCH] MIPS: CM: use __raw_ memory access functions The CM registers use native endianness, so using plain readl & writel will produce incorrect results on big endian systems.
