248  * struct spi_nor - Structure for defining a the SPI NOR layer
251  * @dev:		point to a spi device, or a spi nor controller device.
252  * @info:		spi-nor part JDEC MFR id and other info
253  * @page_size:		the page size of the SPI NOR
260  * @flags:		flag options for the current SPI-NOR (SNOR_F_*)
271  * @read:		[DRIVER-SPECIFIC] read data from the SPI NOR
272  * @write:		[DRIVER-SPECIFIC] write data to the SPI NOR
273  * @erase:		[DRIVER-SPECIFIC] erase a sector of the SPI NOR
275  *			spi-nor will send the erase opcode via write_reg()
276  * @flash_lock:		[FLASH-SPECIFIC] lock a region of the SPI NOR
277  * @flash_unlock:	[FLASH-SPECIFIC] unlock a region of the SPI NOR
278  * @flash_is_locked:	[FLASH-SPECIFIC] check if a region of the SPI NOR is
279  * @quad_enable:	[FLASH-SPECIFIC] enables SPI NOR quad mode
