A35 features disablement/enablement

Dear community,

In Cortex-A35, what features can be disabled or enabled during programming? My code is stuck during the ATF running, but I don't know what ATF doing. My code works well on other parts, but only one part can not work as expected. The chip I am talking about is iMX8QXP from NXP.

What I am trying to get from community is that, I can follow the procedure that community shared to configured the chip to find out either the SW bug or the chip logic defect(most likely happened).

Thanks for your time in advance!

Daniel
