Both virtio-mem and virtio-pmem devices have '.memaddr' attribute which controls the address where they are mapped in the guest memory. Ideally, users do not need to specify this as QEMU does the right thing and computes addresses automatically on startup. But soon, we will need to record this address as it is part of guest ABI. And also, there might be some users that want to control this value. Now, we are in a bit of a pickle, because both these device types already have a PCI address, therefore we can't just use <address/> blindly. But what we can do, is introduce <address/> under the <target/> element. This is also more conceptual, as knobs under <target/> control guest visible config of memory device (and .memaddr surely falls into that category). NB, SgxEPCDeviceInfo struct in QMP definition also has .memaddr attribute, but because of the way we build cmd line there's no (easy) way to set the attribute. So ignore that for now.
