Because we need to get cpu freq in print_cpuinfo at very early stage, so we need to make sure the ccm be probed.

I just upgraded my working tree to v2019.10-rc3 + your v3 MX8MM patches. This somehow breaks things for me. The U-Boot proper hangs when calling uclass_get_device_by_name(). Removing this call makes the boot work again. Do you have any idea what could be wrong? Do I miss something?
Thanks, Frieder
