AFAIR,
 memcpy -s /mnt/tftp/file -d /dev/mem 0 <memaddr> <size>

(but /dev/mem is default value for -d).

If you have tftp command only (old barebox without tftp filesystem support)
then use

 barebox:/ tftp your_file
 barebox:/ memcpy -s your_file 0 0x21f00000 <file size>

Additionally you'll find this:

mkdir /mnt/tftp
automount /mnt/tftp 'ifup eth0 && mount -t tftp $eth0.serverip /mnt/tftp'

which will automount it for you once you need it.
