[U-Boot] Unable to delete the hush shell local variables

[Adarsh Babu Kalepalli]

Hi,

+ u-boot version:2019.10-rc4
+ H/W Board : Beaglebone Black
+ Issue : Unable to delete the hush shell local variables


with 'local_variable_name=' at the shell prompt
(similar to 'setenv env_variable_name'),I tried to
delete a Hush shell local variable after creating it.

This approach did not delete (as in the below sequence of
shell commands)  the local variable.
-----------------------------------------------------
=> hushVar=3
=> showvar
HUSH_VERSION=0.01
hushVar=3
=> hushvar=
=> showvar
HUSH_VERSION=0.01
hushVar=3
=>
------------------------------------------------------

Is there a other approach to delete hush shell local variables ??
Any pointers to detailed information regarding Hush Shell Scripts will also
be helpful.
