[v4] ArmVirtPkg: don't forward the DT to the OS if QEMU provides ACPI

[edk2] [PATCH v4 09/12] ArmVirtPkg: enable AcpiTableDxe and EFI_ACPI_TABLE_PROTOCOL dynamically
Posted by Laszlo Ersek 7 years, 7 months ago
In this patch, the ACPI protocol / driver chain is enabled dynamically,
when appropriate. This is being done in one larger patch, because
ArmVirt.dsc.inc, where AcpiTableDxe is built, is used by all the platform
DSCs.

No change in behavior should be observable after this patch on any
ArmVirtPkg platform.

Notes:
    v4:
    - update pathname of plugin lib instance in dsc.inc to EmbeddedPkg
    - pick up Ard's R-b
    
    v3:
    - don't enable dynamism for 32-bit (ARM) [Ard]
