Did you read the documentation, especially the DULG and it's  section
about  U-Boot's  environment  variables and passing boot arguments to
the Linux kernel?

Actually your question has not much to do with U-Boot but  more  with
the  Linux kernel's boot arguments. You should probably start reading
Documentation/serial-console.txt and "man bootparam".

All versions do.

What makes you think we could know which baudrate you  are  using  on
your system?
