Create verified boot support, which includes verifiication of bootblock. This feature use the vendorcode/eltan/security/lib. Function verified_boot_bootblock_check(), verified_boot_should_run_oprom() and prog_locate_hook() must be called from coreboot (or mainboard). The next lists will be used for verification: bootblock_verify_list[], romstage_verify_list[] ram_stage_additional_list[], ramstage_verify_list[] BUG=N/A TEST=Created binary and verify logging on Facebook FBG-1701 Change-Id: If6c1423b0b4a309cefb7fe7a29d5100ba289e0b4 Signed-off-by: Frans Hendriks <fhendriks(a)eltan.com> --- A src/vendorcode/eltan/security/verified_boot/Kconfig A src/vendorcode/eltan/security/verified_boot/Makefile.inc A src/vendorcode/eltan/security/verified_boot/vboot_check.c A src/vendorcode/eltan/security/verified_boot/vboot_check.h 4 files changed, 605 insertions(+), 0 deletions(-) git pull ssh://review.coreboot.org:29418/coreboot refs/changes/35/30835/1 diff --git a/src/vendorcode/eltan/security/verified_boot/Kconfig b/src/vendorcode/eltan/security/verified_boot/Kconfig new file mode 100644 index 0000000..0670732 --- /dev/null +++ b/src/vendorcode/eltan/security/verified_boot/Kconfig @@ -0,0 +1,61 @@ +## This file is part of the coreboot project. +## +## Copyright (C) 2018 Eltan B.V. +## +## This program is free software; you can redistribute it and/or modify +## it under the terms of the GNU General Public License as published by +## the Free Software Foundation; version 2 of the License. +## +## This program is distributed in the hope that it will be useful, +## but WITHOUT ANY WARRANTY; without even the implied warranty of +## MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
