2019-02-12python: Don't assume SimObjects live in the global namespaceAndreas Sandberg
The importer in Python 3 doesn't like the way we import SimObjects from the global namespace. Convert the existing SimObject declarations to import from m5.objects. As a side-effect, this makes these files consistent with configuration files.

2018-06-07dev-arm: Add a MMIO transport interface for VirtIOAndreas Sandberg
The MMIO interface currently only supports a subset of version 0.9.5 of the VirtIO specification. It has the following known limitations: * The queue size hint (the QUEUE_NUM register) is ignored. * Queue alignment is assumed to be hard-coded to VirtQueue::ALIGN_SIZE (4096 bytes). * Only 4096 byte pages are currently supported.
