Should coreboot/u-boot do this as early as possible too?

It's sort of complicated - coreboot itself is what would have to enable it, but coreboot has no idea what payload is going to be launched (eg, if it's SeaBIOS then something's going to have to remove the state again)

Now if only Intel fixed their iommu - on some systems it is hopelessly broken and causes lots of crashes.
