Subject: binman: Add a convenience functions for real-DTB tests
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=3c0813115b8ebdf940505f6ae5c182d984f49d70;p=u-boot.git

binman: Add a convenience functions for real-DTB tests

Quite a few tests will use a real device tree and need it updated with the
binman metadata. Add a helper function for this.
