None of these application processors I reviewed have out-of-order execution. Cortex-M7 microcontrollers have icache/dcache. You can run bare-metal code on any of these application processors and it will behave more or less like a microcontroller. The lines are really pretty blurry, but the MMU is the big dividing line in my opinion (but it's obviously open for discussion).
