[U-Boot] BUG: Environment is in SPI flash does not even compile (at least for Orange PI PC2

Hi,

I'm trying to compile u-boot with Environment in SPI flash (CONFIG_ENV_IS_IN_SPI_FLASH?) for Orange PI PC2.

Compilation ends with an error: CC env/sf.o env/sf.c: In function ‘env_sf_save’: env/sf.c:266:6: error: ‘CONFIG_ENV_SECT_SIZE’ undeclared (first use in this function); did you mean ‘CONFIG_ENV_SIZE’?

After defining CONFIG_ENV_SECT_SIZE in include/configs/sunxi-common.h linking fails with error: LD u-boot env/built-in.o: In function `setup_flash_device': /root/uboot/u-boot/env/sf.c:71: undefined reference to `spi_flash_probe' env/built-in.o: In function `env_sf_load': /root/uboot/u-boot/env/sf.c:342: undefined reference to `spi_flash_free'

Is there a way to have the environment in the SPI?

Thanks. Regards,
