From: Sebastien Boeuf <sebastien.boeuf@intel.com>

This series aims at adding the support for the Cloud Hypervisor platform
to the OVMF firmware for x86 architecture.

The goal is to allow the same binary to be used either by QEMU or Cloud
Hypervisor, using the Cloud Hypervisor way as a fallback if the fw_cfg
mechanism is not present.

Sebastien Boeuf (5):
  OvmfPkg: Handle Cloud Hypervisor host bridge
  OvmfPkg: Create global entry point for SMBIOS parsing
  OvmfPkg: Retrieve SMBIOS from Cloud Hypervisor
  OvmfPkg: Generalize AcpiPlatformDxe
  OvmfPkg: Install ACPI tables for Cloud Hypervisor

Handle things differently when the detected host bridge matches the
Cloud Hypervisor PCI host bridge identifier.

Add a fallback on the SMBIOS code to find the SMBIOS table for Cloud
Hypervisor if it couldn't be found for Qemu through fw_cfg.

From: Sebastien Boeuf <sebastien.boeuf@intel.com>

Don't make the package Qemu centric so that we can introduce some
alternative support for other VMMs not using the fw_cfg mechanism.

This patch is purely about renaming existing files with no functional
change.
