Hi Aaron, I tried to boot PC Engines apu2 on recent master branch and discovered that it not boot. Bisection points to:

It is hard to believe that this change cause AGESA reset loop, but I checked 3 times. After applying above commit I end up with loop:
I see a similar romstage boot loop starting with this commit on msi/ms7135 (K8N Neo3), a DDR1 K8 board.
I think it's the AMD boards and their weird config. CAR_GLOBAL is used, but apparently these boards fail if accessing CAR_GLOBAL at the wrong time? If you have log diffs w/ and w/o the patch it'd help with root cause.
Jonathan, try this: https://review.coreboot.org/c/coreboot/+/26120
