Subject: [PATCH V4 1/6] remoteproc: elf_loader: fix loading segment when is_iomem true
Date: Fri, 10 Sep 2021 17:06:16 +0800	[thread overview]
Message-ID: <20210910090621.3073540-2-peng.fan@oss.nxp.com> (raw)
In-Reply-To: <20210910090621.3073540-1-peng.fan@oss.nxp.com>

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)
