Ad.1 Board is mk808 (rk3066, patches are on mailing list now)

Ad.2 This happens in spl and U-Boot proper

Ad.3 Function looks like this:

static enum env_location env_get_default_location(void)
{
     if IS_ENABLED(CONFIG_ENV_IS_IN_DATAFLASH)
         return ENVL_DATAFLASH;
     else if IS_ENABLED(CONFIG_ENV_IS_IN_EEPROM)
         return ENVL_EEPROM;
     else if IS_ENABLED(CONFIG_ENV_IS_IN_FAT)
         return ENVL_FAT;
     else if IS_ENABLED(CONFIG_ENV_IS_IN_FLASH)
         return ENVL_FLASH;
     else if IS_ENABLED(CONFIG_ENV_IS_IN_MMC)
         return ENVL_MMC;
     else if IS_ENABLED(CONFIG_ENV_IS_IN_NAND)
         return ENVL_NAND;
     else if IS_ENABLED(CONFIG_ENV_IS_IN_NVRAM)
         return ENVL_NVRAM;
     else if IS_ENABLED(CONFIG_ENV_IS_IN_REMOTE)
         return ENVL_REMOTE;
     else if IS_ENABLED(CONFIG_ENV_IS_IN_SPI_FLASH)
         return ENVL_SPI_FLASH;
     else if IS_ENABLED(CONFIG_ENV_IS_IN_UBI)
         return ENVL_UBI;
     else if IS_ENABLED(CONFIG_ENV_IS_NOWHERE)
         return ENVL_NOWHERE;
     else
         return ENVL_UNKNOWN;
}

So the main reason is "IS_ENABLED(CONFIG_ENV_IS_NOWHERE)" is false
