From 8fc4e0b4273adc741dfd1917970162ca224f98bf Mon Sep 17 00:00:00 2001 From: Masahisa Kojima Date: Fri, 13 Aug 2021 16:12:40 +0900 Subject: efi_loader: add boot variable measurement TCG PC Client PFP spec requires to measure "Boot####" and "BootOrder" variables, EV_SEPARATOR event prior to the Ready to Boot invocation. Since u-boot does not implement Ready to Boot event, these measurements are performed when efi_start_image() is called. TCG spec also requires to measure "Calling EFI Application from Boot Option" for each boot attempt, and "Returning from EFI Application from Boot Option" if a boot device returns control back to the Boot Manager.
