Yes, that's what we have currently:
commit a5a56f07c2726cc801efccd23f8df29af04d6d19 Author: Fabio Estevam <fabio.estevam@nxp.com> Date: Fri Jul 7 12:06:45 2017 -0300

The coda driver may be probed prior to the rootfs being available, leading to firmware loading failure.
To avoid such problem, select the coda driver as module.
