+         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.
