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.

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.

configuration. This patch is needed to read out the correct
configuration. The cfe_env.c file uses a different method way to read
