From b8f73d7f0a1ddc0c0070eef05a017037b1d4b8da Mon Sep 17 00:00:00 2001 From: Stanislav Galabov Date: Mon, 9 May 2016 07:20:02 +0300 Subject: [PATCH] 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.
