> Does this solve any specific problem? I thought CAR stays valid until the end of romstage on all platforms these days? Or do we still use the CAR migration code in romstage somewhere (then this would probably need to be integrated in there somehow)?

No we don't. I tried this when debugging what goes wrong on the xeon_sp/cpx. FSP-M is known to trash some of the CAR region, which could have been an issue.

I'll drop it.
