Subject: dm: test: Add support for running tests with livetree
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=c166c47ba3a699df58e2ade8935158df65b034ba;p=u-boot.git

dm: test: Add support for running tests with livetree

It is useful to run the driver model tests with both livetree and flat
tree in case something is different between the two. Add this feature to
the test runner.
