Subject: [PULL 6/8] tests/vm: support sites with sha512 checksums
Date: Tue, 12 Nov 2019 14:50:26 +0000	[thread overview]
Message-ID: <20191112145028.26386-7-alex.bennee@linaro.org> (raw)
In-Reply-To: <20191112145028.26386-1-alex.bennee@linaro.org>

The NetBSD project uses SHA512 for its checksums so lets support that
in the download helper.
