375 It is used in two contexts:
376 - in memcpy, where data is copied in blocks, the first write
377 of to a block uses movca.l for performance.
378 - in arch/sh/mm/cache-sh4.c, movcal.l + ocbi combination is used
379 to flush the cache. Here, the data written by movcal.l is never
380 written to memory, and the data written is just bogus.
381
382 To simulate this, we simulate movcal.l, we store the value to memory,
383 but we also remember the previous content. If we see ocbi, we check
384 if movcal.l for that address was done previously. If so, the write should
385 not have hit the memory, so we restore the previous content.
386 When we see an instruction that is neither movca.l
387 nor ocbi, the previous content is discarded.
