-Subject: [PATCH 4/6] MIPS: BCM47xx: Setup and register serial early
-
-Swap the first and second serial if console=ttyS1 was set.
-Set it up and register it for early serial support.
-
-This patch has been in OpenWRT for a long time.

-Subject: [PATCH 6/6] MIPS: BCM47xx: Remove CFE console
-
-Do not use the CFE console. It causes hangs on some devices like the
-Buffalo WHR-HP-G54.
-This was reported in https://dev.openwrt.org/ticket/4061 and
-https://forum.openwrt.org/viewtopic.php?id=17063

-The Netgear wgt634u uses a different format for storing the
-configuration. This patch is needed to read out the correct
-configuration. The cfe_env.c file uses a different method way to read
-out the configuration than the in kernel cfe config reader.
