There are some ifdefs missing so when only ssb or only bcma was selected in the kernel config it did not build. git-svn-id: svn://svn.openwrt.org/openwrt/trunk@33209 3c298f89-4303-0410-b956-a3cf2f4a3e73

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.
|
|
|
