How a program is traced in Coreboot? by serial port? or initialization of internal graphics cards? What about those boards with external graphics cards? When it does printk, to what device the message is actually sent?

Why don't you try it and find out!
Joe, I wonder if you can answer my questions if you really know about them. I do not have any mother board with Coreboot support now. I am reviewing the code statically. Regards

Of course I do. I have written code for several of boards in the coreboot tree. And several more I am working on. printk output goes to the serial console until vga starts and then it goes to both until the OS takes over.
Maybe you should get a coreboot running on a board.... no way better to learn than to get your hands dirty, then maybe you will stop asking all these silly newbie questions.

P.S. How do I initialize the cup holder in coreboot?

If a real board is not available, AMD simnow can be used to test one of the AMD projects. It is free and available for both windows and linux. It can even capture the serial output as shown here: http://www.coreboot.org/Build_from_Windows
