OvmfPkg: remove CsmSupportLib
CsmSupportLib 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):
- SYSTEM_ROM_FILE_GUID (1547B4F3-3E8A-4FEF-81C8-328ED647AB1A)
- gEfiFirmwareVolumeProtocolGuid (by cutting the
<Protocol/FirmwareVolume.h> link)
- gEfiLegacyBiosPlatformProtocolGuid
- gEfiLegacyBiosProtocolGuid
- gEfiLegacyInterruptProtocolGuid
- headers:
- FrameworkDxe.h
- Protocol/FirmwareVolume.h
- Protocol/LegacyBiosPlatform.h
- Protocol/LegacyInterrupt.h
which extends the list of resources scheduled for removal to:
- GUIDs (protocols or otherwise):
- SYSTEM_ROM_FILE_GUID (1547B4F3-3E8A-4FEF-81C8-328ED647AB1A)
- gEfiFirmwareVolumeProtocolGuid
- gEfiLegacy8259ProtocolGuid
- gEfiLegacyBiosPlatformProtocolGuid
- gEfiLegacyBiosProtocolGuid
- gEfiLegacyInterruptProtocolGuid
- headers:
- FrameworkDxe.h
- Protocol/FirmwareVolume.h
- Protocol/Legacy8259.h
- Protocol/LegacyBios.h
- Protocol/LegacyBiosPlatform.h
- Protocol/LegacyInterrupt.h
[*] 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.
