[coreboot] how users can control additional features?

[Alexander Couzens]

Hi,

I would like to merge https://review.coreboot.org/c/coreboot/+/12888
But how the user can control this feature (and all other "special
features")?

Should coreboot add an acpi function and the OS offer a UI
(e.g. /sys/class/foo/feature)?
Add a nvram option? (and set a acpi variable based on nvram, so we
don't need SMM)

Any other idea?

Best,
