[U-Boot] OCOTEA Board Serial Port(NS16550)

Hello everyone,

We are in the process of porting ocotea-based U-Boot 2014.04 to custom ppc440gx hardware. Everything is pretty much working except for the serial interface. I am dumping the code through BDI Debugger but it will not Display any thing in Serial Port(Putty or Tera Term).

In debugging the Serial Com port of U-Boot, someone mentioned that a Baud-rate and Frequency might be required for proper operation. Unlike the OCOTEA board, we do NOT have a communication. It means not display any thing, Can anyone tell me about debugging procedure or give some documents?
