MC13213 SRD and NCB Hardware Design Error??

The schematics for the SRD and NCB boards show some signals from Port C connected to IC 104 which is an Atmel AT25HP512. I believe that this is a 65K x 8 bit EEPROM with a serial SPI interface. Unfortunately, Port C isn't the SPI. Unless I'm missing something, I don't see how this chip can ever be driven by the MC13213. Also, you can't simply re-wire the EEPROM to the SPI signals on the MC13213 because they are reserved for use by the wireless transceiver internal to the SOC.

Does anyone else have any ideas?
