That's a good suggestion. Yes, the clock drivers are missing for i.MX8MP.

Here is the comparison against a i.MX8MM EVK:

I will activate them on SPL tomorrow.

Also, I noticed that i.MX8MM EVK has the following watchdog issues on master:

U-Boot SPL 2020.07-rc1-00387-g67887903af (May 07 2020 - 23:49:27 -0300)

It reboots after staying 60s in the U-Boot prompt.

Thanks
