Subject: dtoc: Add a test for code coverage
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=ba765217ed0258fa0ecd5cb77c6c4c171624c4ad;p=u-boot.git

dtoc: Add a test for code coverage

Add a -T option to run a code-coverage test on dtoc. At present this is
about 96%. Future work will increase it to 100%.
