In dwmci_prepare_data, the descriptors are allocated for DMA transfer. These are allocated using the ALLOC_CACHE_ALIGN_BUFFER. This macro uses the stack to allocate these descriptors. This becomes a problem if the DMA transfer continues after the processor leaves the function in which the descriptors were allocated. Therefore, I have moved the allocated of the buffers up one level, to dwmci_send_cmd(). The DMA transfer should be complete when leaving this function.
