Let's please go over this again. Last time I checked, this was the rule:

cores 1 and up don't run in CAR.

Is that true or not. If that is true, then we don't need to worry
about this problem. Cores 1 and up don't
run in CAR. They are started up by core 0 using DRAM.

let's be clear here. When you say AP, do you mean "core > 0" or do mean an AP?

Yes. And it's doable. And, I thought, at least when I worked on the v3
stuff, I did that. Did I not?
