OvmfPkg: remove LegacyBiosDxe
LegacyBiosDxe is not used by any platform at this point, remove it.
This patch removes mentions of the following CSM resources from the source
code [*] [**]:
- GUIDs (protocols or otherwise):
- gEfiIsaIoProtocolGuid
- gEfiLegacy8259ProtocolGuid
- gEfiLegacyBiosGuid
- gEfiLegacyBiosPlatformProtocolGuid
- gEfiLegacyBiosProtocolGuid
- gEfiLegacyInterruptProtocolGuid
- headers:
- FrameworkDxe.h
- Guid/LegacyBios.h
- Protocol/IsaIo.h
- Protocol/Legacy8259.h
- Protocol/LegacyBios.h
- Protocol/LegacyBiosPlatform.h
- Protocol/LegacyInterrupt.h
- PCDs:
- PcdEbdaReservedMemorySize
- PcdEndOpromShadowAddress
- PcdHighPmmMemorySize
- PcdLegacyBiosCacheLegacyRegion
- PcdLowPmmMemorySize
- PcdOpromReservedMemoryBase
- PcdOpromReservedMemorySize
which extends the list of resources scheduled for removal to:
- GUIDs (protocols or otherwise):
- gEfiIsaIoProtocolGuid
- gEfiLegacy8259ProtocolGuid
- gEfiLegacyBiosGuid
- gEfiLegacyBiosPlatformProtocolGuid
- gEfiLegacyBiosProtocolGuid
- gEfiLegacyInterruptProtocolGuid
- headers:
- FrameworkDxe.h
- Guid/LegacyBios.h
- Protocol/IsaIo.h
- Protocol/Legacy8259.h
- Protocol/LegacyBios.h
- Protocol/LegacyBiosPlatform.h
- Protocol/LegacyInterrupt.h
- PCDs:
- PcdEbdaReservedMemorySize
- PcdEndOpromShadowAddress
- PcdHighPmmMemorySize
- PcdLegacyBiosCacheLegacyRegion
- PcdLowPmmMemorySize
- PcdOpromReservedMemoryBase
- PcdOpromReservedMemorySize
[*] Note that gEfiGenericMemTestProtocolGuid, while not a CSM-related
protocol, also becomes useless in the OVMF platforms, so we'll deal with
that later in the series as well.
[**] Note that gEfiLegacyRegion2ProtocolGuid, while a CSM-related
protocol, cannot be scheduled for removal, because the protocol GUID is
defined in "MdePkg.dec", and it's not only "OvmfPkg/Csm/CsmSupportLib"
that produces it in all of edk2, but also
"MdeModulePkg/Universal/LegacyRegion2Dxe" (not used by OVMF). For the same
reason, the "Protocol/LegacyRegion2.h" header (from MdePkg) cannot be
scheduled for removal.
