Hi,

According to env/Kconfig file, seems like below env interfaces are supported. In my understanding, ENV_IS_IN_NAND is used by parallel nand flash while ENV_IS_IN_SPI_FLASH is used by spi nor flash. There is no direct support/interface for spi nand flash. However, we can use ENV_IS_IN_UBI for spi nand flash, which means we can put env into one volume of UBI. Is this correct? If yes, any reason why no direct support/interface for spi nand flash? Thanks！

def_bool y if !ENV_IS_IN_EEPROM && !ENV_IS_IN_EXT4 && \ !ENV_IS_IN_FAT && !ENV_IS_IN_FLASH && \ !ENV_IS_IN_MMC && !ENV_IS_IN_NAND && \ !ENV_IS_IN_NVRAM && !ENV_IS_IN_ONENAND && \ !ENV_IS_IN_REMOTE && !ENV_IS_IN_SPI_FLASH && \ !ENV_IS_IN_UBI
