After MMP has become part of a multiplatform build, we can end up with a randconfig build failure in the pxa2xx spi driver:
drivers/spi/built-in.o: In function `pxa2xx_spi_remove': :(.text+0x1845c): undefined reference to `pxa_ssp_free' drivers/spi/built-in.o: In function `pxa2xx_spi_probe': :(.text+0x19844): undefined reference to `pxa_ssp_request' What happens here is that we can enable SPI_PXA2XX when some other platform in the same build supports PCI. This normally works because the pxa_ssp_request/pxa_ssp_free functions are stubbed out when CONFIG_PXA_SSP is disabled. However, we can have PXA_SSP=m when that driver is used by the SND_SOC_TTC_DKB audio driver. This changes the Kconfig logic to just disallow the pxa2xx SPI driver on anything but x86 and pxa.
