Linus Walleij ee2b805c8e ARM: 5678/1: SSP/SPI PL022 polarity terminology fix 
The definition of the SPI clock phase for the Motorola mode of
the PL022 driver was incorrect: the spec had been interpreted as
data being recieved on rising or falling edge of the clocks while
the correct interpretation is that data can be recieved on the
first or second edge transition, falling or rising depending on
the polarity setting.

Linus Walleij c7c8c78fdf ARM: 5667/3: U300 SSP/SPI board setup and test 
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.
