There's no dedicated SPI interface in MAX II, any SPI functionality has to be implemented in logic elements. Master and slave interfaces are both feasible, but they won't be available for CFM (configuration flash memory) programming, which can be only done through JTAG pins. UFM is accessible through user logic, however.
