/**
 This function offers an interface to modify FSPM_UPD data before the FSP-M API be called.

 @param[in,out]     FspUpdDataPtr                 A pointer to the UPD data region data strcture address.
                                                  It must convert to FSPM_UPD structure for update FSPM UPD.

                                                  If you set this pointer to NULL, FSP API will use the
                                                  default FSP-M UPD settings in the binary.

 @retval            EFI_UNSUPPORTED               Returns unsupported by default.
 @retval            EFI_MEDIA_CHANGED             Alter the Configuration Parameter.
 @retval            EFI_SUCCESS                   The function performs the same operation as caller.
                                                  The caller will skip the specified behavior and assuming
                                                  that it has been handled completely by this function.
