377 * On stepping A0/A1 of the 80200, invalidating D-cache by line doesn't
378 * clear the dirty bits, which means that if we invalidate a dirty line,
379 * the dirty data can still be written back to external memory later on.
381 * The recommended workaround is to always do a clean D-cache line before
382 * doing an invalidate D-cache line, so on the affected processors,
383 * dma_inv_range() is implemented as dma_flush_range().
