X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=217293e399148e704d6c318b19b1f69959831f7b;p=u-boot.git

dm: test: Add a very simple of-platadata test

At present we have a pytest that covers of-platadata. Add a very simple
unit test that just checks that a device can be found. This shows the
ability to write these tests in C.
