From 4abd860ab2a37732778f06fdc56da45598005b14 Mon Sep 17 00:00:00 2001 From: Hauke Mehrtens Date: Wed, 13 Nov 2013 18:38:18 +0000 Subject: [PATCH] brcm47xx: swap also early boot console if necessary. Some devices are using tty1 as the default console, also swap the early boot console in such case. This is needed for the WGT634U. Thank you Russell for reporting this.
