We can have drivers supplied by U-Boot and drivers supplied by an EFI
binary that we recently installed via the bootefi command.

A driver installed via the bootefi command will not have allocated
memory for the extra fields.

So you cannot use the name field in your "efitool drivers" command.

Best regards
