- * it needs about what devices are present via the device tree.
- * There are some restrictions about what we can do here:
- * + we can only present devices whose Linux drivers will work based
- * purely on the device tree with no platform data at all
- * + we want to present a very stripped-down minimalist platform,
- * both because this reduces the security attack surface from the guest
- * and also because it reduces our exposure to being broken when
- * the kernel updates its device tree bindings and requires further
- * information in a device binding that we aren't providing.
- * This is essentially the same approach kvmtool uses.

- * order are mapped to virtio-mmio buses with decreasing base addresses.

- * function of this loop, qbus_realize(), qbus_find_recursive(), and the

- *
- * Meanwhile, the kernel's traversal seems to have been reversed; see eg.
- * the message, if not necessarily the code, of commit 70161ff336.
- * Therefore the loop now establishes the inverse of the original intent.
- *
- * Unfortunately, we can't counteract the kernel change by reversing the
- * loop; it would break existing command lines.
- *
- * In any case, the kernel makes no guarantee about the stability of
