Subject: nds32/io: Remove useless definition of mmiowb()
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=335b5c638bfd72b959b22c80f65dea3f614b6cca;p=openwrt%2Fstaging%2Fblogic.git

nds32/io: Remove useless definition of mmiowb()

mmiowb() only makes sense for SMP platforms, so remove it entirely for
nds32.
