config: coreboot-x230: add force=1 to tpm_tis Linux driver
Browse files Browse the repository at this point in the history
Add tpm_tis.force=1: "Force device probe rather than using ACPI entry".

This prevents Linux from "hanging" for about 30 seconds after
"switched to clocksource tsc" when loading this driver.

TPM measurements seem to work, but we should look for the change in coreboot
that causes this problem.
