The SPI NOR controllers drivers must not be able to use structures that are meant just for the SPI NOR core. struct spi_nor_flash_parameter is filled at run-time with info gathered from flash_info, manufacturer and sfdp data. struct spi_nor_flash_parameter should be opaque to the SPI NOR controller drivers, make sure it is. spi_nor_option_flags, spi_nor_read_command, spi_nor_pp_command, spi_nor_read_command_index and spi_nor_pp_command_index are defined for the core use, make sure they are opaque to the SPI NOR controller drivers.
