Both SND_MPC52xx_SOC_PCM030 and SND_MPC52xx_SOC_EFIKA select
SND_SOC_MPC5200_AC97. The latter symbol depends on PPC_BESTCOMM,
so the 2 former symbols should also depend on PPC_BESTCOMM since

Even though dma-iommu.c and CONFIG_ARM_DMA_USE_IOMMU do approximately the

dma-iommu.c expects the core code to setup an UNMANAGED domain (of type
IOMMU_DOMAIN_DMA) and then configures itself to use that domain. This

This allows a driver to set a global static to an IDENTITY domain and
