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

[kope at madnet.sk]

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,
