/**
|
|
The entry point of PE/COFF Image for a DXE Driver, DXE Runtime Driver, DXE SMM Driver, or UEFI Driver.
|
|
|
|
This function is the entry point for a DXE Driver, DXE Runtime Driver, DXE SMM Driver,
|
|
or UEFI Driver. This function must call ProcessLibraryConstructorList() and
|
|
ProcessModuleEntryPointList(). If the return status from ProcessModuleEntryPointList()
|
|
is an error status, then ProcessLibraryDestructorList() must be called. The return value
|
|
from ProcessModuleEntryPointList() is returned. If _gDriverUnloadImageCount is greater
|
|
than zero, then an unload handler must be registered for this image and the unload handler
|
|
must invoke ProcessModuleUnloadList().
|
|
If _gUefiDriverRevision is not zero and SystemTable->Hdr.Revision is less than _gUefiDriverRevison,
|
|
then return EFI_INCOMPATIBLE_VERSION.
|
|
