From dbe24b039d381365b62c02802016f108c3efe8eb Mon Sep 17 00:00:00 2001 From: Leah Rowe Date: Wed, 31 Jul 2024 12:26:25 +0100 Subject: coreboot/default: Update to 97bc693ab (2024-07-29) Several patches are now merged upstream and no longer needed in lbmk, such as the HP EliteBook 8560w patch, and related patches. Some patches were changed, for example the Dell Latitude ivb/snb laptops are now variants in coreboot, instead of being individual ports; now they re-use the same base code. This this, the corresponding files under config/submodules have changed, for things like 3rdparty submodules e.g. libgfxinit, and tarballs e.g. crossgcc. This is long overdue, and will enable more boards to be added. This newer revision will be used in the next release, and some follow-up patches will merge these trees into default: * coreboot/haswell * coreboot/dell Signed-off-by: Leah Rowe --- ...-ifdtool-add-nuke-flag-all-0xFF-on-region.patch | 205 +++++++++++++++++++++ 1 file changed, 205 insertions(+) create mode 100644 config/coreboot/default/patches/0013-util-ifdtool-add-nuke-flag-all-0xFF-on-region.patch (limited to 'config/coreboot/default/patches/0013-util-ifdtool-add-nuke-flag-all-0xFF-on-region.patch') diff --git a/config/coreboot/default/patches/0013-util-ifdtool-add-nuke-flag-all-0xFF-on-region.patch b/config/coreboot/default/patches/0013-util-ifdtool-add-nuke-flag-all-0xFF-on-region.patch new file mode 100644 index 00000000..9d4270e7 --- /dev/null +++ b/config/coreboot/default/patches/0013-util-ifdtool-add-nuke-flag-all-0xFF-on-region.patch @@ -0,0 +1,205 @@ +From 70cf6905b54d39285025373dae1c897c9c727f83 Mon Sep 17 00:00:00 2001 +From: Leah Rowe +Date: Sun, 19 Feb 2023 18:21:43 +0000 +Subject: [PATCH 13/39] util/ifdtool: add --nuke flag (all 0xFF on region) + +When this option is used, the region's contents are overwritten +with all ones (0xFF). + +Example: + +./ifdtool --nuke gbe coreboot.rom +./ifdtool --nuke bios coreboot.com +./ifdtool --nuke me coreboot.com + +Rebased since the last revision update in lbmk. + +Signed-off-by: Leah Rowe +--- + util/ifdtool/ifdtool.c | 114 ++++++++++++++++++++++++++++++----------- + 1 file changed, 83 insertions(+), 31 deletions(-) + +diff --git a/util/ifdtool/ifdtool.c b/util/ifdtool/ifdtool.c +index 32b2081d93..1473cf058b 100644 +--- a/util/ifdtool/ifdtool.c ++++ b/util/ifdtool/ifdtool.c +@@ -2204,6 +2204,7 @@ static void print_usage(const char *name) + " tgl - Tiger Lake\n" + " wbg - Wellsburg\n" + " -S | --setpchstrap Write a PCH strap\n" ++ " -N | --nuke Overwrite the specified region with 0xFF (all ones)\n" + " -V | --newvalue The new value to write into PCH strap specified by -S\n" + " -v | --version: print the version\n" + " -h | --help: print this help\n\n" +@@ -2212,6 +2213,60 @@ static void print_usage(const char *name) + "\n"); + } + ++static int ++get_region_type_string(const char *region_type_string) ++{ ++ if (!strcasecmp("Descriptor", region_type_string)) ++ return 0; ++ else if (!strcasecmp("BIOS", region_type_string)) ++ return 1; ++ else if (!strcasecmp("ME", region_type_string)) ++ return 2; ++ else if (!strcasecmp("GbE", region_type_string)) ++ return 3; ++ else if (!strcasecmp("Platform Data", region_type_string)) ++ return 4; ++ else if (!strcasecmp("Device Exp1", region_type_string)) ++ return 5; ++ else if (!strcasecmp("Secondary BIOS", region_type_string)) ++ return 6; ++ else if (!strcasecmp("Reserved", region_type_string)) ++ return 7; ++ else if (!strcasecmp("EC", region_type_string)) ++ return 8; ++ else if (!strcasecmp("Device Exp2", region_type_string)) ++ return 9; ++ else if (!strcasecmp("IE", region_type_string)) ++ return 10; ++ else if (!strcasecmp("10GbE_0", region_type_string)) ++ return 11; ++ else if (!strcasecmp("10GbE_1", region_type_string)) ++ return 12; ++ else if (!strcasecmp("PTT", region_type_string)) ++ return 15; ++ return -1; ++} ++ ++static void ++nuke(const char *filename, char *image, int size, int region_type) ++{ ++ int i; ++ struct region region; ++ const struct frba *frba = find_frba(image, size); ++ if (!frba) ++ exit(EXIT_FAILURE); ++ ++ region = get_region(frba, region_type); ++ if (region.size > 0) { ++ for (i = region.base; i <= region.limit; i++) { ++ if ((i + 1) > (size)) ++ break; ++ image[i] = 0xFF; ++ } ++ write_image(filename, image, size); ++ } ++} ++ + int main(int argc, char *argv[]) + { + int opt, option_index = 0; +@@ -2219,6 +2274,7 @@ int main(int argc, char *argv[]) + int mode_em100 = 0, mode_locked = 0, mode_unlocked = 0, mode_validate = 0; + int mode_layout = 0, mode_newlayout = 0, mode_density = 0, mode_setstrap = 0; + int mode_read = 0, mode_altmedisable = 0, altmedisable = 0, mode_fmap_template = 0; ++ int mode_nuke = 0; + int mode_gpr0_disable = 0, mode_gpr0_enable = 0, mode_gpr0_status = 0; + char *region_type_string = NULL, *region_fname = NULL; + const char *layout_fname = NULL; +@@ -2254,6 +2310,7 @@ int main(int argc, char *argv[]) + {"validate", 0, NULL, 't'}, + {"setpchstrap", 1, NULL, 'S'}, + {"newvalue", 1, NULL, 'V'}, ++ {"nuke", 1, NULL, 'N'}, + {0, 0, 0, 0} + }; + +@@ -2303,35 +2360,8 @@ int main(int argc, char *argv[]) + region_fname++; + // Descriptor, BIOS, ME, GbE, Platform + // valid type?
