Detailed Description

QEMU device abstraction as a SystemC module.

This class abstract a QEMU device as a SystemC module. It is constructed using the QEMU instance it will lie in, and the QOM type name corresponding to the device. This class is meant to be inherited from by children classes that implement a given device.

The elaboration flow is as follows:

At construct time, nothing happen on the QEMU side.
When before_end_of_elaboration is called, the QEMU object correponding to this component is created. Children classes should always call the parent method when overriding it. Usually, they start by calling it and then set the QEMU properties on the device.
When end_of_elaboration is called, the device is realized. No more property can be set (unless particular cases such as some link properties) and the device can now be connected to busses and GPIO.
