The altera quad spi core is very special that the hardware handle the
spi-nor protocol. The core is designed to replace the CFI flash
interface. So there is nothing to do with SPI from the parallel flash
interface. It is memory mapped. There is no SPI interface. There is
nothing related to SPI programming. So please don't worry about the
progress on spi-nor. The core should belong to parallel flash, but not
serial flash.

Best regards,
Thomas
