[Qemu-devel] [PATCH 0/9] hw/misc: Clean the empty_slot device

[Philippe Mathieu-Daudé]

Hi, this is another clean-up series, paving the road for a later
series touching the GT64120 north bridge.

It makes the EMPTY_SLOT more in shape with the UNIMPLEMENTED_DEVICE,
and slighly more powerful (allowing overlapping, trace events).

Previous discussions with Artyom and Peter:

- https://lists.gnu.org/archive/html/qemu-devel/2018-10/msg00235.html
  'TYPE_EMPTY_SLOT is not UNIMPLEMENTED_DEVICE'

- https://lists.gnu.org/archive/html/qemu-devel/2018-10/msg00336.html
  '"no bus errors when this range is touched" behaviour'

- https://lists.gnu.org/archive/html/qemu-devel/2018-10/msg00292.html
  'background region with the "RAZ/WI" behaviour'

Regards,

Phil.
