This adds a U300 board configuration for the PL022 SSP/SPI PrimeCell driver recently merged to the 2.6.31-rc series. Further it adds a dummy loopback SPI chip that can be used for testing the SPI functionality on a running system using the loopback mode of PL022.

This creates a small kernel module that creates a dummy

SPI device to be used for loopback tests. Regularly used

to test reference designs. If you're not testing SPI,

you don't need it. Selecting this will activate the

SPI framework and ARM PL022 support.
