Bug #629: TPM Deactivation x230
https://ticket.coreboot.org/issues/629

* Author: Richard Hiltrude
* Status: New
* Priority: High
* Category: Payloads
* Target version: main
* Start date: 2026-02-22
* Affected versions: main
* Affected hardware: x230
----------------------------------------
When I try to disable TPM on the x230 and turn it off, there is no option to 
save, only the ESC key.

When I press ESC, it restarts, but when I access the TPM menu again, everything 
is still active!

SeaBIOS 1.17.0

Perhaps there is also an error in SeaBIOS.

cbmem log
TPM: flags disable=0, deactivated=0, nvlocked=1
