Это не с scsi_transport_spi перепутано?

Вообще-то в drivers/spi/ лежит вот что:

config SPI
        bool "SPI support"
        help
          The "Serial Peripheral Interface" is a low level synchronous
          protocol.  Chips that support SPI can have data transfer rates
          up to several tens of Mbit/sec.  Chips are addressed with a
          controller and a chipselect.  Most SPI slaves don't support
          dynamic device discovery; some are even write-only or read-only.
          
          SPI is widely used by microcontollers to talk with sensors,
          eeprom and flash memory, codecs and various other controller
          chips, analog to digital (and d-to-a) converters, and more.
          MMC and SD cards can be accessed using SPI protocol; and for
          DataFlash cards used in MMC sockets, SPI must always be used.
        
          SPI is one of a family of similar protocols using a four wire
          interface (select, clock, data in, data out) including Microwire
          (half duplex), SSP, SSI, and PSP.  This driver framework should
          work with most such devices and controllers.


config SPI_BITBANG
        tristate "Bitbanging SPI master"
        depends on SPI_MASTER && EXPERIMENTAL
        help
          With a few GPIO pins, your system can bitbang the SPI protocol.
          Select this to get SPI support through I/O pins (GPIO, parallel
          port, etc).  Or, some systems' SPI master controller drivers use
          this code to manage the per-word or per-transfer accesses to the
          hardware shift registers.
          
          This is library code, and is automatically selected by drivers that
          need it.  You only need to select this explicitly to support driver
          modules that aren't part of this kernel tree.
          
config SPI_BUTTERFLY
        tristate "Parallel port adapter for AVR Butterfly (DEVELOPMENT)"
        depends on SPI_MASTER && PARPORT && EXPERIMENTAL
        select SPI_BITBANG
        help
          This uses a custom parallel port cable to connect to an AVR
          Butterfly <http://www.atmel.com/products/avr/butterfly>, an
          inexpensive battery powered microcontroller evaluation board.
          This same cable can be used to flash new firmware.
