If yes then it might be possible that you defined CFG_SERIAL_CONFIG_QUIET or CFG_CONSOLE_CONFIG_QUIET something similar
(I do not recall the exact name and do not have the sources with me right now.)
Then it does not print out this information.
Otherwise it might be possible that your u-boot environment maps these on other ports. (and the rest of the information is send to these ports).
Or perhaps that U-Boot crashes before the initialisation of the console is started.
