From d1f408f3725aa02bc1d76c4c6aadb4697bd073c0 Mon Sep 17 00:00:00 2001 From: Francis Rowe Date: Sat, 02 Jan 2016 17:10:32 -0500 Subject: Use different coreboot revisions and patches per board The release archives will be bigger, but this is a necessary change that makes libreboot development easier. At present, there are boards maintained in libreboot by different people. By doing it this way, that becomes much easier. This is in contrast to the present situation, where a change to one board potentially affects all other boards, especially when updating to a new version of coreboot. Coreboot-libre scripts, download scripts, build scripts - everything. The entire build system has been modified to reflect this change of development. For reasons of consistency, cbfstool and nvramtool are no longer included in the util archives. --- (limited to 'resources/scripts/helpers/download/coreboot') diff --git a/resources/scripts/helpers/download/coreboot b/resources/scripts/helpers/download/coreboot index 9c34e05..a080c84 100755 --- a/resources/scripts/helpers/download/coreboot +++ b/resources/scripts/helpers/download/coreboot @@ -2,7 +2,7 @@ # helper script: downloads coreboot and patches/deblobs it # -# Copyright (C) 2014, 2015 Francis Rowe +# Copyright (C) 2014, 2015, 2016 Francis Rowe # Copyright (C) 2015 Paul Kocialkowski # # This program is free software: you can redistribute it and/or modify @@ -25,6 +25,95 @@ [ "x${DEBUG+set}" = 'xset' ] && set -v set -u -e +if [ -f "version" ]; then + # _src release archive is being used + version="libreboot-$(cat version)" +else + # git repo is being used + version="libreboot-$(git describe --tags HEAD)" +fi + +# sanity check (check for invalid paths in the reused.list patch lists before proceeding) +for payloads in resources/libreboot/config/*; do + + if [ !
