Subject: ramips: introduce serial0 aliases
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=b8f73d7f0a1ddc0c0070eef05a017037b1d4b8da;p=openwrt%2Fstaging%2Fyousong.git

ramips: introduce serial0 aliases

This patch introduces serial0 aliases in the ramips DTS files, which can
then be used to denote the active console instead of relying on bootargs.
