Subject: virtio: sandbox: Bind RNG rather than block device
X-Git-Url: http://git.dujemihanovic.xyz/login.html?a=commitdiff_plain;h=acd3b27a6564b94ffd2d4cf0c2726816bc1bffc3;p=u-boot.git

virtio: sandbox: Bind RNG rather than block device

The virtio-rng driver is extremely simple, making it suitable for
testing more of the virtio uclass logic. Have the sandbox driver bind
the virtio-rng driver rather than the virtio-blk driver so it can be
used in tests.
