Ralf Baechle 554b7f56b9 MIPS: BMIPS: Flush the readahead cache after DMA. ... BMIPS 3300/435x/438x CPUs have a readahead cache that is separate from the L1/L2. During a DMA operation, accesses adjacent to a DMA buffer may cause parts of the DMA buffer to be prefetched into the RAC. To avoid possible coherency problems, flush the RAC upon DMA completion.
