From 19efdf9eebaf60038f652e870f58aea4b1f14b6d Mon Sep 17 00:00:00 2001 From: Leah Rowe Date: Sun, 3 Sep 2023 19:55:58 +0100 Subject: ich9m mainboards: use pre-assembled ifd/gbe files This cuts down on build time, and it will allow libreboot to remove large chunks of code. these ifd/gbe configs are just binary-encoded config files, in a format well-understood. they can easily be opened up and displayed, using ich9show or ifdtool, and manipulated by these tools; bincfg can generate them from scratch, and nvmutil can change mac addresses, for example. so, do this and remove from lbmk the following: * ich9utils (which contains ich9gen) - not needed anymore * code in lbmk for handling ich9gen and insertions; the coreboot build system is now used, for this same purpose, so remove such code from lbmk this results in a massive code size reduction (thousands of lines) in lbmk; smaller when only looking at the build system, but much larger when you consider that ich9utils is also removed (about 3k sloc) Signed-off-by: Leah Rowe --- util/ich9utils/src/common/descriptor_gbe.c | 90 ------------------------------ 1 file changed, 90 deletions(-) delete mode 100644 util/ich9utils/src/common/descriptor_gbe.c (limited to 'util/ich9utils/src/common/descriptor_gbe.c') diff --git a/util/ich9utils/src/common/descriptor_gbe.c b/util/ich9utils/src/common/descriptor_gbe.c deleted file mode 100644 index 1c1ad32b..00000000 --- a/util/ich9utils/src/common/descriptor_gbe.c +++ /dev/null @@ -1,90 +0,0 @@ -/* - * descriptor_gbe.c - * This file is part of the ich9deblob utility from the libreboot project - * - * Purpose: common descriptor/gbe functions used by ich9deblob - * - * Copyright (C) 2014, 2015 Leah Rowe - * Copyright (C) 2014 Steve Shenton - * - * 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, either version 3 of the License, or - * (at your option) any later version. - * - * 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.
