STM32F4: How can I move code into fast RAM?

So far I've been using the STM32F722, but I'm planning to switch to either STM32F446 or STM32F429.

On the F722, I moved speed-critial code to ITCM RAM. The F4s don't have ITCM RAM, but an ICache and/or CCM. How do I move code to any fast RAM and execute it with 0 wait states on the F4? (It seems like the caches are meant to ensure 0 wait state execution, but I'd like to be sure.)
