Change all '$(...)' variable references into '${...}'
which makes the environment compatible with the hush shell.
WARNING: Support for the old '$(...)' syntax will be
discontinued in a later version.

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"
