Well, they may not have speculative execution,but some of them do have branch prediction these days; which probably leaks a certain amount of information. Eg, the cortex M7 (no mmu,mpu optional, has branch prediction)

I think Cortex-M7 also often has split I+D caches?
Yes. That's what Arm supply, a SoC vendor may add a unified second level.
