Subject: upl: Add an end-to-end test
X-Git-Url: http://git.dujemihanovic.xyz/%22/img/sics.gif/%22/static/git-favicon.png?a=commitdiff_plain;h=3403422767650d3ff4f3129ee959e1b5de525161;p=u-boot.git

upl: Add an end-to-end test

Now that sandbox_vpl supports UPL, add a test that checks that the
payload can be loaded by SPL and the handoff information passed through
to U-Boot proper.
