Try #2, now that ARM has the fix from http://gerrit.chromium.org/gerrit/4667 This cleans up the TPM calls inside vboot_reference. * TPM calls share mode code between boot modes. * Better handling for TPM_E_MUST_REBOOT, particularly in recovery mode. * TAB screen shows current TPM versions. No changes required to the wrapper API; these changes are internal to vboot. BUG=chromium-os:18084 TEST=make && make runtests; built for both alex and tegra2-seaboard Original-Change-Id: I2a52066f2889210af83409872b10f9d6380470af (cherry picked from commit da55560cddcf7a1aa8a881cdf52792a21a01e766) Change-Id: I120797145772116f09b8125b9e56fdbb11dc16b3 Reviewed-on: http://gerrit.chromium.org/gerrit/4671 Tested-by: Randall Spangler <rspangler@chromium.org> Reviewed-by: Randall Spangler <rspangler@chromium.org>
