At least, they are not as specific as the name implies. There are SPI memory controllers which are indeed "specialized" and optimized for handling "memories", but most of them are just generic and accept almost any kind of opcode, address, dummy and data cycles, making them as suitable for NANDs than NORs. Furthermore, this controller supports any kind of bus, from single to octal NAND, so make it clear. Also add a comment to mention that the initial compatible naming is too specific (but obviously kept for backward compatibility reasons).
