-- CONFIG_ENV_IS_IN_SPI_FLASH:
-
-	Define this if you have a SPI Flash memory device which you
-	want to use for the environment.
-
-	- CONFIG_ENV_OFFSET:
-	- CONFIG_ENV_SIZE:
-
-	  These two #defines specify the offset and size of the
-	  environment area within the SPI Flash. CONFIG_ENV_OFFSET must be
-	  aligned to an erase sector boundary.
-
-	- CONFIG_ENV_SECT_SIZE:
-
-	  Define the SPI flash's sector size.
-
-	- CONFIG_ENV_OFFSET_REDUND (optional):
-
-	  This setting describes a second storage area of CONFIG_ENV_SIZE
-	  size used to hold a redundant copy of the environment data, so
-	  that there is a valid backup copy in case there is a power failure
-	  during a "saveenv" operation. CONFIG_ENV_OFFSET_REDUND must be
-	  aligned to an erase sector boundary.
-
-	- CONFIG_ENV_SPI_BUS (optional):
-	- CONFIG_ENV_SPI_CS (optional):
-
-	  Define the SPI bus and chip select. If not defined they will be 0.
-
-	- CONFIG_ENV_SPI_MAX_HZ (optional):
-
-	  Define the SPI max work clock. If not defined then use 1MHz.
-
-	- CONFIG_ENV_SPI_MODE (optional):
-
-	  Define the SPI work mode. If not defined then use SPI_MODE_3.
-
 - CONFIG_ENV_IS_IN_REMOTE:
 
 	Define this if you have a remote memory space which you
