Add Altera Generic Quad SPI Controller support. The controller converts SPI NOR flash to parallel flash interface. So it is not like other SPI flash, but rather like CFI flash.
Can you wait till spi-nor ready? it doesn't make sense to have Serial NOR to created as parallel NOR.
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.
