1.Measure ACPI table data comes from flash event type EV_POST_CODE ACPI DATA to PCR[0]
2.Re-measure ACPI table after fix up with event type EV_EFI_HANDOFF_TABLES to PCR[1] Signed-off-by : Chao Zhang<chao.b.zhang@intel.com> Reviewed-by : Dong Guo<guo.dong@intel.com> Reviewed-by : Yao Jiewen<jiewen.yao@intel.com> git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@13964 6f19259b-4bc3-4df7-8a09-765794883524
