Subject: [PATCH V2 48/69] ST SPEAr: replace readl, writel with __raw_readl, __raw_writel in uncompress.h
Date: Fri, 1 Oct 2010 17:26:08 +0530 [thread overview]
Message-ID: <10581ee8e7ad68eabb4421cee448b5f7df983adb.1285933332.git.viresh.kumar@st.com> (raw)
In-Reply-To: <cover.1285933331.git.viresh.kumar@st.com>
readl also calls outer cache maintainance operations which are not available
during Linux uncompression. This patch replaces readl, writel with __raw_readl
and __raw_writel.
