The QSPI driver provides the interface for using an on-board QSPI flash for the filesystem. It provides the same methods as the driver for the internal flash and uses the same name. Therefore, only one of the drivers for internal flash, SPI flash and QSPI flash must be enabled at a time. Signed-off-by: robert-hh <robert@hammelrath.com>
