I need to skip all these 4 functions to run through, otherwise it hangs. What causes this? or what setting is not right?
Did you fix your ME issue yet? it might be futile to make assumptions about the hardware if the ME is no running correctly.
If you are sure your ME is doing well and all four functions above fail individually, there may be multiple issues. I'd start by diving deeper into those function and find the first hardware access that makes it hang.
The first function enables SMIs based on devicetree settings. Make sure these settings match your hardware (or set them to zero if in doubt, to rule them out).

Refcode is added and VGA BIOS passes. hangs at "Set power off after power failure. "
It seems that the ME is not 100% right.
