Yes. This is a broadwell platform. I removed the UPD settings and left them default (passed NULL for that pointer in the parameters to FspInit). It seems to get past that point now. I did notice that the SMBus addresses for the DIMMs were being set to different values than what is listed in the binary configuration tool. This and the PMBASE settings were really the only things changed in the coreboot source. Maybe this is the cause?
I don't really have any logs as I'm only debugging with port 0x80 values.
