The ST IoT discovery board has a macronix mx25r6435f nor flash memory. I've attached a driver for the chibios serial nor device. This has been lightly tested but seems to work for WSP1,2,and 4 modes.

Important Note: the stm32 quadspi device doesn't properly handle the WP# line for programming except quad program. To use spi, wspi1, wspi2 you must pull that pin high.
