+config SPI
+	bool "SPI Driver Support"
+	default n
+	---help---
+		This selection enables selection of common SPI options.  This option
+		should be enabled by all platforms that support SPI interfaces.
+		See include/nuttx/spi/spi.h for further SPI driver information.
+
+if SPI
+config SPI_OWNBUS
+	bool "SPI single device"
+	default n
+	---help---
+		Set if there is only one active device on the SPI bus.  No locking or
+		SPI configuration will be performed. It is not necessary for clients to
+		lock, re-configure, etc..
+
+config SPI_EXCHANGE
+	bool "SPI exchange"
+	default y
+	---help---
+		Driver supports a single exchange method (vs a recvblock() and
+		sndblock() methods).
+
+config SPI_CMDDATA
+	bool "SPI CMD/DATA"
+	default n
+	---help---
+		Devices on the SPI bus require out-of-band support to distinguish
+		command transfers from data transfers.  Such devices will often support
+		either 9-bit SPI (yech) or 8-bit SPI and a GPIO output that selects
+		between command and data.
