I need an idea on how to copy the value of an environment variable into RAM.

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

Let's say serial#=ABC1234, then I want to get ABC1234 into RAM at address 0x100000. Is this possible with some tricky u-boot commands?

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...
