[U-Boot-Users] Serial init of both SMC and SCC

Hi people,
I'm trying to get three serial ports up and running simultaneously. I'm using slightly modified TQM823L based board (added FPGA) with serials on SMC1, SMC2 and SCC3. The problem is to get SCC3 alive into Linux. A detailed study of the problem follows shows that when using 
SCC3 for console in u-boot, it also works in Linux, but when using SMC1 (or SMC2) for console, SCC3 does not work in Linux. So I have come to my own humble conclusion that it has something to do with the initialization of the serial devices in u-boot. Long story short:

I _really_ want the console on SMC1 and I need the SCC3 serial working on the side. Are there any appropriate ways of achieving this (I've tried enabling both SMC1 and SCC3 for console but that did not do the trick)?

Regards,
Bjorn Ostby
