Enrty point to DXE 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.
