The utils.c contains wrappers and implementation for accessing iomem mapped regions and a single unrelated function to create a compressed page table from snd_dma_buffer for firmware use. The latter is used by the PCM and the dma trace code and it needs to be moved to a generic source/header for the client conversion to be possible.
