Subject: [PATCH] remoteproc: elf_loader: fix loading segment when is_iomem true
Date: Mon, 28 Jun 2021 15:06:57 +0800	[thread overview]
Message-ID: <20210628070657.7669-1-peng.fan@oss.nxp.com> (raw)

From: Peng Fan <peng.fan@nxp.com>

It seems luckliy work on i.MX platform, but it is wrong.
Need use memcpy_toio, not memcpy_fromio.

Fixes: 40df0a91b2a52 ("remoteproc: add is_iomem to da_to_va")
Tested-by: Dong Aisheng <aisheng.dong@nxp.com> (i.MX8MQ)
