[Qemu-devel] [PATCH v1 06/11] memory-device: add device class function set_addr() |

To be able to factor out address asignment of memory devices, we will
have to read (get_addr()) and write (set_addr()) the address. We cannot
use properties for this purpose, as properties are device specific. E.g.
while the address property for a DIMM is called "addr", it might be
called differently (e.g. "phys_addr") for other devices. E.g. virtio
based memory devices cannot use "addr" as that is already reserved and
used for the virtio device address on the bus.
