Introduction

While Coreboot contains and uses nonfree software, it is the upstream for Libreboot. It also contains a wide variety of projects.

This means that we have to care about the upstream status of computers that can be supported by Libreboot. And we also need FSDG compliant ways to be able to use and package the tools that are developed in the Coreboot source tree.

Tools

Computers status

This section is for computers that worked with either Coreboot or Libreboot at some point, and that can or could have been added to Libreboot mostly as-is.

Original vendors	Model(s)	Maintainer(s)	Chipset or microarchitecture family	Status	Last review
Acer	G43T-AM3	Unmaintained	Intel G43	Seem fine. Also has native GPU initialization.	Coreboot 4.21
Apple	iMac 5,2 Macbook 1,1 Macbook 2,1	Evgeny Zinoviev	Intel I945	Free software GPU intialization in Coreboot 4.21, probably in C since there is no ada source code in the mainboard directory.^[1] Looks fine otherwise	Coreboot 4.21

Adding newer computers in Coreboot and Libreboot

This section is for listing computers that were never supported by Coreboot or by Libreboot, but that may be added relatively easily.

The goal here is to list computers that are similar enough to already supported computers and that could be added without having to add new drivers for specific hardware (like adding support for ATI or Nvidia GPUs) and without getting rid of some existing nonfree software (like the SMU for AMD computers).

Original vendors	Model(s)	Chipset family	Comments
Lenovo	ThinkPad SL300 (with Intel GPU only) ThinkPad SL400 (with Intel GPU only) ThinkPad SL400c ThinkPad SL410 ThinkPad SL500 (with Intel GPU only) ThinkPad SL500c ThinkPad SL510	Intel GM45	According to ThinkWiki these laptops have an Intel GM45. According to ThinkWiki these laptops have an "IdeaPad firmware", which means that "as such some of the ThinkPad specific drivers and features are not supported.". I've made some tests on one of these (Maybe it was the SL410) and thinkpad_acpi was loaded. Though I cound't do dangerous tests on the EC (embedded controller), so I don't know the differences.

GNU Boot patches

Patch	Type
0001-apple-macbook21-Set-default-VRAM-to-64MiB-instead-of.patch	Configuration
0002-add-c3-and-clockgen-to-apple-macbook21.patch	Needs upstreaming
0003-lenovo-x60-64MiB-Video-RAM-changed-to-default-previo.patch	Configuration
0004-lenovo-t60-make-64MiB-VRAM-the-default-in-cmos.defau.patch	Configuration
0005-lenovo-t400-set-VRAM-to-352MiB-VRAM-by-default.patch	Configuration
0006-lenovo-x200-set-VRAM-to-352MiB-by-default.patch	Configuration
0007-gigabyte-ga-g41m-es2l-set-VRAM-to-352MiB-by-default.patch	Configuration
0008-acer-g43t-am3-set-VRAM-to-352MiB-by-default.patch	Configuration
0009-Revert-cpu-intel-Configure-IA32_FEATURE_CONTROL-for-.patch	Revert: can we upstream it, or do we need to maintain it?
0010-Fix-missing-include.patch	Build system related, needs upstreaming
0011-lenovo-t400-Enable-all-SATA-ports.patch	Needs upstreaming
0012-fix-speedstep-on-x200-t400-Revert-cpu-intel-model_10.patch	Revert: can we upstream it, or do we need to maintain it?
0015-python-patch.patch	Build system related, needs upstreaming

In addition there are two patch for flashrom to enable installing GNU Boot/Libreboot on GM45 Thinkpads without disassembling the laptop. They are needed otherwise the flash chip are not detected. Since the flash chip have different IDs it's not possible to remove the need of the patches by trying to not read/write the whole flash.
