Subject: [PATCH V4 6/6] remoteproc: imx_rproc: change to ioremap_wc for dram
Date: Fri, 10 Sep 2021 17:06:21 +0800 [thread overview]
Message-ID: <20210910090621.3073540-7-peng.fan@oss.nxp.com> (raw)
In-Reply-To: <20210910090621.3073540-1-peng.fan@oss.nxp.com>
From: Dong Aisheng <aisheng.dong@nxp.com>
DRAM is not io memory, so changed to ioremap_wc. This is also
aligned with core io accessories. e.g. memcpy/memset and cpu direct
access.
