[U-Boot] cant not enter uboot command line

[Detlev Zundel]

Hi "zs",

> SMDK2416 # U-Boot 1.1.6 (Sep 24 2009 - 10:24:40) for SMDK2416
> Unknown command 'U-Boot' - try 'help'

U-Boot 1.1.6 is _really old_.  Please try with a recent version of
U-Boot from the git repository.

Also it somewhat looks like you're UART is in loopback mode if it
interprets the U-Boot banner output as input.  But that's just a pure
guess, the number of unreadable output messages in your log is
overwhelming.

Cheers
   Detlev
