+ * Emulate a virtual board which works by passing Linux all the information
+ * 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.
