Subject: [PATCH v3 5/5] remoteproc: imx_rproc: change to ioremap_wc for dram
Date: Thu, 5 Aug 2021 11:32:06 +0800 [thread overview]
Message-ID: <20210805033206.1295269-5-aisheng.dong@nxp.com> (raw)
In-Reply-To: <20210805033206.1295269-1-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.
