265  * struct spi_nor - Structure for defining a the SPI NOR layer
268  * @dev:		point to a spi device, or a spi nor controller device.
269  * @info:		spi-nor part JDEC MFR id and other info
270  * @page_size:		the page size of the SPI NOR
280  * @flags:		flag options for the current SPI-NOR (SNOR_F_*)
291  * @read:		[DRIVER-SPECIFIC] read data from the SPI NOR
292  * @write:		[DRIVER-SPECIFIC] write data to the SPI NOR
293  * @erase:		[DRIVER-SPECIFIC] erase a sector of the SPI NOR
295  *			spi-nor will send the erase opcode via write_reg()
296  * @flash_lock:		[FLASH-SPECIFIC] lock a region of the SPI NOR
297  * @flash_unlock:	[FLASH-SPECIFIC] unlock a region of the SPI NOR
298  * @flash_is_locked:	[FLASH-SPECIFIC] check if a region of the SPI NOR is
299  * @quad_enable:	[FLASH-SPECIFIC] enables SPI NOR quad mode
