* 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.
