I remember having lockup issues with the mainline TF-A and i.MX8MM when it came to power domain handling (with older kernels and preliminary power domain support). I never tracked this down, but switched to the NXP TF-A for the time being. IIRC the mainline TF-A doesn't enable the USB power domains per default, while the NXP TF-A does and there are probably other differences. With the latest GPCv2 and BLK-CTRL code in the kernel it should work either way, but there still might be some unresolved problems.
