This device tree will be consumed by Coconut SVSM with the upcoming device tree support [1]. This will allow SVSM to run on a normal CPU (not AMD SEV-SNP) and execute all its tests using upstream QEMU.
Eventually edk2 will also be able to consume DT via IGVM, but the work has not started yet. This series contains one patch that simplifies meson logic and another one that changes the return behaviour of `qigvm_find_param_entry`. This is to avoid conflicts with the device tree patch itself, that needs to modify the same lines.
