An iopmem device is one which exposes volatile or non-volatile memory mapped
directly to a BAR region. One purpose is to provide buffers to do peer
to peer transfers on the bus. As such this device uses QEMU's drive
backing store to simulate non-volatile memory and provides through a
mapped BAR win

Looks okay, but I wonder how bdrv_drain_all releasing AioContext break anything?

This adds a qbus to the floppy controller that should contain the floppy
drives eventually. At the moment it just exists and is empty.

This makes the FloppyDrive qdev object actually useful: Now that it has
all properties that don't belong to the controller, you can actually
use '-device floppy' and get a working result.
Command line semantics is consistent with CD-ROM drives: By default you
get a single empty floppy drive. You c
We have been complaining for a long time about how the floppy controller and
floppy drives are combined in a single qdev device and how this makes the
device awkward to work with because it behaves different from all other block
devices.
The latest reason to complain was when I noticed that using
Floppy controllers automatically create two floppy drive devices in qdev
now. (They always created two drives, but managed them only internally.)
