coreboot image signature
by Benoit SANSONI 19 Aug '16

19 Aug '16

Hi all, I would like to know if it is possible, via a signature or a magic number, in the coreboot.rom file to recognize that it is a "coreboot" file. I did not find anything in the Makefile.inc. Thanks in advance

ifdtool newlayout errors
by Nicola Corna 19 Aug '16

19 Aug '16

Hi everyone, I have a Thinkpad X220t with coreboot and I'm trying to replace the 5MB ME firmware with the small (2MB) one, extracted from a Sandy Bridge Chromebook. The small ME blob works but now I want to reclaim the free space by modifying the Intel descriptor, partly following the x220 guide (https://www.coreboot.org/Board:lenovo/x220#Bigger_SPI_ROM). If I extract the layout and modify it from 00000000:00000fff fd 00500000:007fffff bios 00003000:004fffff me 00001000:00002fff gbe 00fff000:00000fff pd 00fff000:00ffffff res1 00fff000:00ffffff res2 00fff000:00ffffff res3 00000000:00ffffff ec to 00000000:00000fff fd 00183000:007fffff bios 00003000:00182fff me 00001000:00002fff gbe 00fff000:00000fff pd 00fff000:00ffffff res1 00fff000:00ffffff res2 00fff000:00ffffff res3 00000000:00ffffff ec ifdtool --newlayout fails with "Region would overlap."

GNU Libreboot, version 20160818 released
by Leah Rowe 18 Aug '16

18 Aug '16

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 GNU Libreboot 20160818 This is a brand GNU release. Libreboot joined the GNU project on 14 May 2016. This 18 August 2016 release is the first GNU release of libreboot. Get it from https://libreboot.org/download/ NEW BOARDS ADDED: * ASUS Chromebook C201 (ARM laptop) (thanks to Paul Kocialkowski) * Gigabyte GA-G41M-ES2L motherboard (desktop) (thanks to Damien Zammit) * Intel D510MO motherboard (desktop) (thanks to Damien Zammit) * ASUS KCMA-D8 motherboard (desktop) (thanks to Timothy Pearson) * ASUS KFSN4-DRE motherboard (server) (thanks to Timothy Pearson) * ASUS KGPE-D16 motherboard (server) (thanks to Timothy Pearson) For details development history on these boards, refer to the git log and documentation. For boards previously supported, many fixes from upstream have been merged. Other changes (compared to libreboot 20150518), for libreboot in general or for previously supported systems: (this is a summary. For more detailed change list, refer to the git log) 256MiB VRAM allocated on GM45 (X200, T400, T500, R400) instead of 32MiB. This is an improvement over both Lenovo BIOS and Libreboot 20150518, allowing video decoding at 1080p to be smoother. (thanks Arthur Heymans) To clarify, GM45 video performance in libreboot 20160818 is better than on the original BIOS and the previous libreboot release. 64MiB VRAM on i945 (X60, T60, MacBook2,1) now supported in coreboot-libre, and used by default (in the previous release, it was 8MiB allocated). Thanks to Arthur Heymans. Higher battery life on GM45 (X200, T400, T500, R400) due to higher cstates now being supported (thanks Arthur Heymans). C4 power states also supported. Higher battery life on i945 (X60, T60, MacBook2,1) due to better CPU C-state settings. (Deep C4, Dynamicl L2 shrinking, C2E). Text mode on GM45 (X200, T400, T500, R400) now works, making it possible to use MemTest86+ comfortably. (thanks to Nick High from coreboot) Dual channel LVDS displays on GM45 (T400, T500) are now automatically detected in coreboot-libre. (thanks Vladimir Serbinenko from coreboot) Partial fix in coreboot-libre for GRUB display on GM45, for dual channel LVDS higher resolution LCD panels (T400, T500). (thanks Arthur Heymans) Massively improved GRUB configuration, making it easier to boot more encrypted systems automatically, and generally a more useful menu for booting the system (thanks go to Klemens Nanni of the autoboot project). Libreboot now uses the grub.cfg provided by the installed GNU/Linux distribution automatically, if present, switching to that configuration. This is done across many partitions, where libreboot actively searches for a configuration file (also on LVM volumes and encrypted volumes). This should make libreboot more easy to use for non-technical users, without having to modify the GRUB configuration used in libreboot. Utilities archives is now source only. You will need to compile the packages in there (build scripts included, and a script for installing build dependencies in Trisquel 7). (binary utility archives are planned again in the next release, when the new build system is merged) SeaGRUB is now the default payload on all x86 boards. (SeaBIOS configured to load a compressed GRUB payload from CBFS immediately, without providing an interface in SeaBIOS. This way, GRUB is still used but now BIOS services are available, so you get the best of both worlds). Thanks go to Timothy Pearson of coreboot for this idea. crossgcc is now downloaded and built as a separate module to coreboot-libre, with a universal revision used to build all boards. Individual boards now have their own coreboot revision and patches, independently of each other board. This makes maintenance easier. Updated all utilities, and modules (coreboot, GRUB, etc) to newer versions, with various bugfixes and improvements upstream. RTC century byte issue now fixed on GM45 in coreboot-libre, so the date should now be correctly displayed when running the latest linux kernel, instead of seeing 1970-01-01 when you boot (thanks to Alexander Couzens from coreboot) Build system now uses multiple CPU cores when building, speeding up building for some people. Manually specifying how many cores are needed is also possible, for those using the build system in a chroot environment. (thanks go to Timothy Pearson from coreboot) In the build system (git repository), https:// is now used when cloning coreboot. http:// is used as a fallback for GRUB, if git:// fail s. New payload, the depthcharge bootloader (free bootloader maintained by Google) for use on the ASUS Chromebook C201. (thanks go to Paul Kocialkowski) Various fixes to the ich9gen utility (e.g. flash component density is now set correctly in the descriptor, gbe-less descriptors now supported) The official documentation included in the release in provided in texinfo format, instead of HTML; this was one of the requirements for joining GNU. (the other requirement is a new build system, to comply with GNU standards, e.g. Makefiles, and common Makefile entries present in all GNU software. As of Libreboot 20160818, this new build system is not yet merged, but will be in the release afterwards) ChangeLog and NEWS files are included in the release, to comply with GNU standards (they are dumps of the git-log output) - -- Leah Rowe Libreboot developer Use free software.

Re: [coreboot] Coreboot is failing to build
by Ali H. Fardan 18 Aug '16

I actually worked around it, it was some MITM proxy that decompresses the gzipped tarball, for some reason, that didn't happen why I tried fetching libelf tarball from https://www.mirrorservice.org/sites/libreboot.org/release/20150518/crossgcc… but anyway, I was able to build coreboot and I flashed it but it seems that I bricked the board, it showed multiple flash chips and I had to choose, so I picked the first one and everything went alright until I rebooted. I am going to flash it externally now, any tips so I don't screw up this time? Raiz

> I'm with Zoran; see if you can decompress manually. It looks like he suggested a > different option style, too. Exactly what I did. Decompressed it manually with tar -xf, to see what will happen (works seamlessly). Could be done with -xvf (v in the middle: verbose, for debug traces). I would warmly suggest to everyone to use the latest distros, with most recent upgrades. Since these are tested, mostly, and they have latest and greatest features enhanced, and added. Here is what I have after last upgrade of my Fedora 24 VM on my HP UltraBook WIN10 laptop half an hour ago (following Martin's Roth advice): [zoran@localhost libelf]$ uname -r 4.6.6-300.fc24.x86_64 [zoran@localhost libelf]$ tar --version tar (GNU tar) 1.28 Copyright (C) 2014 Free Software Foundation, Inc.
