So you did a "real" board port to your custom board? Or did you "just" change 
the yosemite files?

Ah, I though you wanted the console on UART1. Ok, then my solution does not 
work for you.

Best would be to add the 3rd UART (UART2) to the SERIAL_MULTI infrastructure 
(see end of serial.c) and use this device as "stdin/stdout/.." in your
