If you need default values may be you couldn't define these so-that
common/env_sf.c
will take the defaults for undefs - please check.
Default values are defined in mx6slevk.h
#define CONFIG_SF_DEFAULT_BUS 0
#define CONFIG_SF_DEFAULT_CS 0
#define CONFIG_SF_DEFAULT_SPEED 20000000
#define CONFIG_SF_DEFAULT_MODE SPI_MODE_0
In env_sf.c
I did not see any undefs, there is only a piece of code like:
#ifndef CONFIG_ENV_SPI_BUS
#define CONFIG_ENV_SPI_BUS 0
#endif
+#else
+#define CONFIG_ENV_OFFSET (6 * SZ_64K)
#define CONFIG_ENV_IS_IN_MMC
+#endif
#define CONFIG_OF_LIBFDT
#define CONFIG_CMD_BOOTZ
