[PATCH v4 0/3] Enable Cloud Hypervisor support in edk2

Jianyong Wu

Cloud Hypervisor is an open source Virtual Machine Monitor (VMM) that
runs on top of KVM. Cloud Hypervisor is implemented in Rust and is based
on the rust-vmm crates. See [1] to find more.

To support UEFI, Cloud Hypervisor is introduced here.
There are 2 parts to be considered to do this enablement, that is:
1. specific ACPI service implementation compared with qemu, there is no
device like Fw-cfg, so we have no elegant way to get the RSDP address.
A specific ACPI implementation is introduced here.

2. build configuration file for Cloud Hypervisor

Change log:

v3 to v4:
(1) remove Tpm support in dsc file
(2) refine Acpi table install code base on Sami's comments in v3

v2 to v3:
(1) reuse qemu's memory initialization lib as they are in nearly the same
memory laout.
(2) split Acpi implemetation into PlatformHasAcpi and
(3) remove lots of dependencies from qemu like "*Fwcfg*" lib.
(4) lots of code cleanup work to let it more approach to edk2 code
