Let me understand is this FlexSPI is spi-nor controller, is it Linux upstreamed or ML? I think for now you can add it mtd/spi with UCLASS_SPI_FLASH driver, Since Boris mentioned about spi-mem(I still need to see the Linux framework for more details) which may be re-placer for spi-nor but once we decided to go with spi-mem or spi-nor then the flexspi can convert accordingly.
