[Qemu-devel] [PATCH v6 25/27] virtio-blk: add bootindex to qom property

[arei.gonglei]

From: Gonglei <address@hidden>

Add a qom property with the same name 'bootindex',
when we remove it form qdev property, things will
continue to work just fine, and we can use qom features
which are not supported by qdev property.
