All environment ariables are already stored in RAM when U-Boot is
running.

Ah! you mean, you want to have the copy on a specific address :-)
I'm afraid there is no way to do this. We don;t have a comand that
takes a strin on input and stores it to a specific address, and we
don't have enough of shell tools to split and convert to hex either.
You probaly will have to to implement the "mw.s" (memory write
string) command...
Best regards,
