Subject: config_cmd_default.h: Add 'env exists' command
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=293eac363d7866948d6a99b13d4c53c5ccc00132;p=u-boot.git

config_cmd_default.h: Add 'env exists' command

env exists allows scripts to query whether an environment variable
exists. Enable by default as it adds only a trivial amount of code and
can be useful in scripts.
