Re: [U-Boot] [PATCH v4 03/17] string: Use memcpy() within memmove() when we can

A common use of memmove() can be handled by memcpy(). Also memcpy() includes an optimisation for large sizes: it copies a word at a time. So we can get a speed-up by calling memcpy() to handle our move in this case.

Update memmove() to call memcpy() if the destination is before the source.
