Nico, I faced this same thing earlier I believe. The reason I disabled it was to stop coreboot from writing to the flash chip. I was advised to turn off CONFIG_ENABLE_FSP_FAST_BOOT and this worked for the flash but had this side affect.
Garrett, Are you disabling it for the same reason?

AFAICS, the Bay Trail FSP doesn't have such an option. So it might be the case that the binary always expects a non-volative cache. But that is disabled in coreboot if you disable ENABLE_FSP_FAST_BOOT (by chance). Intel is known to present options where only one value works. The correct solution seems to be to always `select ENABLE_MRC_CACHE` for fsp_baytrail and remove the related guards in its code. And hide ENABLE_FSP_FAST_BOOT for fsp_baytrail because it just doesn't apply. May I ask why you want to disable fast boot?
