To generate ACPI table for PCIe controller, we need the base and size of the PCIe ranges. Record these ranges in MemMapEntry array, then we could share and use them for generating ACPI table.

* 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.
