+/*++

+Routine Description:
+ According to a file guild, check a Fv file device path is valid. If it is invalid,
+ try to return the valid device path.
+ FV address maybe changes for memory layout adjust from time to time, use this funciton
+ could promise the Fv file device path is right.
+
+Arguments:
+ DevicePath - on input, the Fv file device path need to check
+ on output, the updated valid Fv file device path
+
+ FileGuid - the Fv file guild
+
+Returns:
+ EFI_INVALID_PARAMETER - the input DevicePath or FileGuid is invalid parameter
+ EFI_UNSUPPORTED - the input DevicePath does not contain Fv file guild at all
+ EFI_ALREADY_STARTED - the input DevicePath has pointed to Fv file, it is valid
+ EFI_SUCCESS - has successfully updated the invalid DevicePath, and return the updated
+ device path in DevicePath
