OvmfPkg: Add a build flag to select ISA driver stack
REF:https://bugzilla.tianocore.org/show_bug.cgi?id=1495
This commit will add a static build flag 'USE_LEGACY_ISA_STACK' to select
the ISA driver stack.
If the flag is set to TRUE, the below driver stack will be used:
PcAtChipsetPkg/IsaAcpiDxe/IsaAcpi.inf
IntelFrameworkModulePkg/Bus/Isa/IsaBusDxe/IsaBusDxe.inf
IntelFrameworkModulePkg/Bus/Isa/IsaSerialDxe/IsaSerialDxe.inf
IntelFrameworkModulePkg/Bus/Isa/Ps2KeyboardDxe/Ps2keyboardDxe.inf
If the flag is set to FALSE, the below driver stack will be used:
OvmfPkg/SioBusDxe/SioBusDxe.inf
MdeModulePkg/Bus/Pci/PciSioSerialDxe/PciSioSerialDxe.inf
MdeModulePkg/Bus/Isa/Ps2KeyboardDxe/Ps2KeyboardDxe.inf
The default value is set to FALSE in OVMF DSC files.
