[PATCH v2 0/3] hw: Fix reset of bus-less devices |

Hi,
This series is the result of a code audit of the DeviceClass::reset()
method uses, having Markus following explanation in mind [1]:
"Propagating reset from the root of the qtree to the leaves
won't reach a bus-less device, because the qtree contains
only the devices that plug into a qbus."
Which is a resumed of what Peter said earlier in the thread [2].
Since v1:
- removed spapr_iommu patch (2 different reset is intentional)
- removed microdrive patch (pcmcia cards should plug into a bus)
- use device_cold_reset() instead of device_legacy_reset
- use ResettableClass instead of deprecated DeviceClass::reset
(patch changed -> not carrying David A-b tag)
Philippe Mathieu-Daudé (3):
hw/block/nand: Register machine reset handler
hw/pci-host/raven: Manually reset the OR_IRQ device
hw/arm/armsse: Manually reset the OR_IRQ devices
hw/arm/armsse.c | 4 ++++
hw/block/nand.c | 14 ++++++++++++++
hw/pci-host/prep.c | 11 +++++++++++
