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