Disable tiny printf in SPL, because that's really broken with dm_dump_all(), run dm_dump_all() just after power_init_board() in board/freescale/imx8m{p,q}_evk/spl.c and compare the results. There is likely gonna be a missing driver, my bet would still be on the clock.
That's a good suggestion. Yes, the clock drivers are missing for i.MX8MP.
Here is the comparison against a i.MX8MM EVK: https://pastebin.com/raw/XVc6AAvr
I will activate them on SPL tomorrow.
Also, I noticed that i.MX8MM EVK has the following watchdog issues on master:
