The existing sandbox implementation of virtio only tests the basic API.
It is not able to provide a block device, for example.
Add a new implementation which operations at a higher level. It makes
use of the existing MMIO driver to perform virtio operations.
This emulator-device should be the parent of a function-specific
emulator. That emulator uses this MMIO transport to communicate with the
controller:
virtio-blk {
compatible = "sandbox,virtio-blk-emul";
mmio {
compatible = "sandbox,virtio-emul";
};
};
A new UCLASS_VIRTIO_EMUL uclass is created for the child devices, which
implement the actual function (block device, random-number generator,
etc.)
