Subject: Makefile: fix newline escaping for CONFIG_DEFAULT_ENV_FILE
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=47e8ee6b39a47dc0bbde43049dc83dbc48dcdb56;p=u-boot.git

Makefile: fix newline escaping for CONFIG_DEFAULT_ENV_FILE

I wanted this to be compatible with mkenvimage, including the ability
to embed newlines in variables by escaping them. But I failed to check
that it works more than once.

Fixes: f3d8f7dd73a (Allow providing default environment from file)
