Typically to the first serial port on the board. Some chipsets/boards
can also use EHCI Debug Port. And finally there is support for
sending console output over UDP using a RTL8029 NIC.

If coreboot is configured to initialize a VGA option ROM (rare and
not recommended, normally handled by SeaBIOS) then any printk()
following that initi (usually none) would also be visible on the
monitor.

LXR can be helpful for browsing the code.  printk is a macro defined
in console.h
