I will add this patch to the nds32 port series.
From: Greentime Hu <greentime@...estech.com>
Date: Wed, 21 Feb 2018 14:21:23 +0800
Subject: [PATCH] xtensa: add ioremap_nocache declaration before include
asm-generic/io.h.
A future commit for the nds32 architecture bootstrap("asm-generic/io.h:
move ioremap_nocache/ioremap_uc/ioremap_wc/ioremap_wt out of ifndef
CONFIG_MMU") will move the ioremap_nocache out of the CONFIG_MMU ifdef.
This means that in order to suppress re-definition errors we need to
setup #define's before importing asm-generic/io.h.
