+config SPI_GPIO_CUSTOM
+       tristate "Custom GPIO-based SPI driver"
+       depends on GENERIC_GPIO
+       select SPI_GPIO
+       help
+         This is an SPI driver to register 1 to 4 custom SPI buses using
+         GPIO lines. Each bus can have up to 8 slaves.
+         The devices will be exposed to userspace as /dev/spidevX.X
+         
+         This module is maily intended to interface microcontrollers
+         and other SPI devices without a specific kernel driver.
+
+         This support is also available as a module.  If so, the module
+         will be called spi-gpio-custom.
