See http://www.denx.de/twiki/bin/view/DULG/LinuxRamdiskRoot (and
previous sections).

What's "unlock" ?

Makes no sense. Traget address  should  be  !=  source  address.  Use
"$(filesize)" instead of filesize.

If you just copy from RAM to RAM then why not TFTP to 300000?
Also, "$(filesize)" is required.

This does not do what you think yo do. I guess what you want is more like

setenv bootcmd 'tftp 200000 kernelimage;tftp 300000 uInitRD;bootm 200000 300000'

> 	saveenv bootm

Syntax error. "saveenv" does not take arguments.

You _can_ do this, but it won't make you happy ;-)
