Jim Quinlan a6079a371f MIPS: DMA: For BMIPS5000 cores flush region just like non-coherent R10000 ... commit f86f55d3ad upstream. The BMIPS5000 (Zephyr) processor utilizes instruction speculation. A stale misprediction address in either the JTB or the CRS may trigger a prefetch inside a region that is currently being used by a DMA engine, which is not IO-coherent. This prefetch will fetch a line into the scache, and that line will soon become stale (ie wrong) during/after the DMA. Mayhem ensues. In dma-default.c, the r10000 is handled as a special case in the same way that we want to handle Zephyr. So we generalize the exception cases into a function, and include Zephyr as one of the processors that needs this special care.
