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

60320182d011 console: only allow console messages after initialization

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:

coreboot-4.7-441-g60320182d0 Fri Mar  2 15:22:24 UTC 2018 romstage
starting...
BSP Family_Model: 00730f01
cpu_init_detectedx = 00000000
agesawrapper_amdinitreset() entry

CBFS: 'Master Header Locator' located CBFS at [200:7fffc0)

Fch OEM config in INIT RESET Done

Any idea what can be result of such weird behavior?
