[U-Boot] How to enable to print messages on serial port(ttyS0) in u-boot?

[sunr2007]

Dear all ,
Is there a option to print the message or some variable value which i av
modified in code to print it on serial console to check whether it is
getting executed or not? like we use printf in application programming . if
yes how to enable it and  use it? . thanks.
warm regards,
Ravi Kulkarni.
