Currently Xilinx Zynq qspi supports these type of connections. - CONFIG_SPI_FLASH_MTD spi-flash MTD layer - - Define this option to use mtd support for spi flash layer, this - adapter is for translating mtd_read/mtd_write commands into - spi_flash_read/spi_flash_write commands. It is not intended to - use it within sf_cmd or the SPI flash subsystem.
