What if we use exiting SPI_FLASH_MACRONIX for it? does it increasing size much? if not go for exiting macro.
I want to seperate SPI_FLASH_MACRONIX and SPI_FLASH_MACRONIX_OCTAL for enabling Macronix octal support. Refer to your suggestions, checking SPI_FLASH_MACRONIX and other configuration which means octal enable is better. But I didn't found the existing configuration means "octal enable". It would be great if you can recommend the suitable configuration set for nor->fixups hooks macronix_octal_fixups. I will have v5 patchwork with the configuration checking.
Thanks Jaime
