Hi all, I have a slightly off-topic question regarding the use of mpc52xx_lpbfifo_submit() & friends...
In struct mpc52xx_lpbfifo_request, the element 'data' (with address 'data_phys') is apparently the chunk of data which is transferred through bestcomm, right? Dumb question: has this chunk of memory to be DMA mem (i.e. allocated via dma_alloc_coherent), or is "normal" kernel memory (kmalloc) sufficient? Thanks, Albrecht.
