Change subject: mainboard/ocp/monolake: If memory is locked down, clear TPM and reset
......................................................................

Patch Set 1:

According to the txt spec if "secrets in memory" and ungraceful shutdown happened, you need to either boot with a trusted IBB that can scrub memory or if the IBB isn't trusted any more pull the CMOS battery to clear the sticky bit.

If clearing the TPM 'fixes' that for you that's a hardware bug.
