I kind of agree with Tim's sentiment, having each platform kick all of these off manually gets pretty clunky. We kinda had a bit of this discussion in https://review.coreboot.org/c/coreboot/+/56051/8..18/src/lib/Kconfig#b102 already. I think ideally we'd just have one central point in the generic code of each stage (e.g. early in hardwaremain.c for ramstage) where it automatically kicks off all preloads, and the platform shouldn't have to worry about it anymore (other than enabling the right Kconfigs). What are your remaining concerns with that?
