Passing runtime data to the payload #1560
Description
The problem you're addressing (if any)
We need a way to pass dynamic configuration data to the payload. EFI variables work, but aren't ideal, for example in cases where the variable store is not initialized yet. See: Dasharo/coreboot#760
Describe the solution you'd like
An interface to pass runtime configuration variables to the payload. CFR can do this.
Where is the value to a user, and who might that user be?
More consistent behavior than EFI variables.
