[U-Boot-Users] Changing all '$(...)' variable references into '${...}'

Hello everybody,

please note that I have checked in a patch to change all '$(...)' variable references into '${...}'.

In case you did not know: this syntax has been supported for > 18 months. The big advantage is that such an environment definition is compatible with the hush shell, i. e. when you decide to switch the command line parser there is no trouble with your environment definitions.

Note that the old syntax [i. e. '$(...)'] will be discontinued in later versions of U-Boot. Please use '${...}' instead.

Best regards,

Wolfgang Denk
