Now that FSP2 is public, we need to test with the public files (how to get fsps.bin and fspm.bin from that fsp.fd file?) and push upstream the fsp2 support.
If we drop/remove the vr_config stuff from the devicetree, then the choice between fsp1.1 or fsp2 can become a KConfig choice instead of having the port force us to move either this way or that.
If sata issues are only fixed with fsp2, then we can drop fsp1.1 of course.
