Subject: virtio: Add a block device
X-Git-Url: http://git.dujemihanovic.xyz/html/index.html?a=commitdiff_plain;h=00fc8cade89e36855fe8143c4ee66e951a41734e;p=u-boot.git

virtio: Add a block device

The test code for virtio is fairly simplistic and does not actually create
a block device. Add a way to specify the device type in the device tree.
Add a block device so that we can do more testing.
