Ok, so that's what I thought: you're missing a call to at91_mciX_hw_init in your
board init code. This function assigns the correst I/O pins to the MCI
controller and takes care of enabling the clock. Please have a look at at91_mciX_hw_init
cpu/arm926ejs/at91/at91sam9260_devices.c to see what arguments the function expects.

The CONFIG_ATMEL_SPI change is in mainline, yes. Other parts of the patch
aren't.
