The SSP has PCI configuration indicating how it is being assigned, which is in vendor capability byte 6. The low 3 bits indicte the mode, where mode 1 is an SPI master/slave, and in that case bit 6 is set for a slave. The SSP/SPI driver will only grab ports that have been assigned to that purpose as part of the system design. I'm just putting the other bits from the generic driver back into the more featured/tested specific driver that Russ posted.
