From 4397aa1347551f3f4a277f8587e1fe8fbcffc3e6 Mon Sep 17 00:00:00 2001 From: Duncan Laurie Date: Mon, 12 May 2014 10:22:01 -0700 Subject: vboot: Add a new post code for TPM failure MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit If the kernel does not properly handle the TPM and send it a TPM_SaveState command before suspend then it will not be in the correct state on resume. In order to easily detect this case add a new post code for TPM failure and use it in the vboot resume path. BUG=chromium:371105 TEST=Build and boot on wtm2.
