> Aaron, on what chipset did that happen and which functions didn't do it right?

I want to say apollolake, skylake, or glk. I did a brief search and found apollolake had an issue on LPC block: https://review.coreboot.org/c/coreboot/+/16426 That was involving the termination pulls. I recall an EMMC issue as well, however I didn't hvae time to dig that one up.

I'm not sure we want to figure out the whole list of things that are or are not updated when in NF mode because if we write a value that is overwritten by the IP block that implements once we put the pad in NF mode then there's no regression. However, if we have instances of different behavior from experience why would we risk changing current behavior?
