 You can put these commands into some environment variables;
 
 => setenv load tftp 100000 u-boot.bin
-=> setenv update protect off all\;era FFF00000 FFF3FFFF\;cp.b 100000 FFF00000 \$(filesize)\;saveenv
+=> setenv update protect off all\;era FFF00000 FFF3FFFF\;cp.b 100000 FFF00000 \${filesize}\;saveenv
 => saveenv
 
 Then you just have to type "run load" then "run update"
