From 94e78200244c076e3343fd8105ffa77d73327025 Mon Sep 17 00:00:00 2001 From: Ilias Apalodimas Date: Mon, 30 Nov 2020 11:47:41 +0200 Subject: cmd: efidebug: Add support for TCG2 final events table A previous commit is adding EFI_TCG2_PROTOCOL, which in it's eventlog support registers an EFI configuration table. Let's add the necessary GUID so 'efidebug table' command can display table names properly.
