The only question I have: why calling dma_unmap_single() from within a spinlock is a bad practice?
I don't know, but usually functions that allocate or free memory cannot be called from within a spinlock. You need to check that. Since the MPC5121 is a single-core CPU, you might not notice if you're doing something wrong.
