A serial console port is a sequential stream of bytes without any such
notation as "screen". Thus there is no command to clear a "screen":,
and there cannot be any such command.

Assuming you connect the serial data stream to some terminal or
terminal emulator, this (emulated device) might have such features,
and provide ways to perform any such actions on it. And it may even be
possible to use for example the "echo" command to send the required
(device specific) sequence of control characters - but this is nothing
that has anything to do with U-Boot.



Best regards,
