The workaround-mx patch was rebased on one section in spi.c, because that part in upstream added QPI support; in the newly rebase mx patch, the workaround_mx behaviour is only honoured if QPI (Quad SPI) is not in use. Quad SPI is not used in practise, on the machines where this workaround is intended (GM45 ThinkPads with Macronix chips).

Canoeboot
Find canoeboot documentation at https://canoeboot.org/
The canoeboot project provides
libre boot
firmware that initializes the hardware (e.g. memory controller, CPU,
peripherals) on specific Intel/AMD x86 and ARM targets, which
then starts a bootloader for your operating system. Linux/BSD are
well-supported. It replaces proprietary BIOS/UEFI firmware. Help is available
via #canoeboot IRC
on Libera IRC.
Canoeboot is maintained in parallel with Libreboot, by the same developer. Strictly speaking, it is a fork of Libreboot, but with a twist:
Canoeboot is provided for the purists who absolutely wish to have no proprietary software of any kind. Regardless of any other firmware that exists outside of it, the boot flash on your system will be entirely free software if you install Canoeboot on it. That includes a complete lack of CPU microcode updates, as per FSF policy.
More specifically: Canoeboot is engineered to comply with the GNU Free System Distribution Guidelines. It has, as of November 2023 releases, been strictly audited by FSF licensing staff (Craig Topham lead the audit), and it is listed on the FSF's own Free Software Directory.
Libreboot previously complied with that same policy, but changed to a different one permitting binary blobs in limited circumstances, so as to support more newer machines. Canoeboot is, then, a continuation of the traditional Libreboot project prior to that policy change. Some users still want it, so, Canoeboot releases are rigoriously maintained, re-basing on newer Libreboot releases over time, just like how, say, Trisquel, re-bases itself on each new Ubuntu release.
Project goals
- Obviously, support as much hardware as possible (within the limitations imposed by GNU FSDG, and using what coreboot happens to have in its source tree - Canoeboot also heavily patches coreboot, sometimes adding new mainboards out-of-tree).
- Make coreboot easy to use. Coreboot is notoriously difficult to install, due to an overall lack of user-focused documentation and support. Most people will simply give up before attempting to install coreboot. Canoeboot's automated build system and user-friendly installation instructions solves this problem.
Canoeboot attempts to bridge this divide by providing a build system automating much of the coreboot image creation and customization. Secondly, the project produces documentation aimed at non-technical users. Thirdly, the project attempts to provide excellent user support via IRC.
Canoeboot already comes with a payload (GRUB), flashprog and other needed parts. Everything is fully integrated, in a way where most of the complicated steps that are otherwise required, are instead done for the user in advance.
You can download ROM images for your canoeboot system and install them without having to build anything from source. If, however, you are interested in building your own image, the build system makes it relatively easy to do so.
Not a coreboot fork!
Canoeboot is not a fork of coreboot. Every so often, the project re-bases on the latest version of coreboot, by virtue of maintaining sync with Libreboot releases (minus un-GNU parts), with the number of custom patches in use minimized. Tested, stable (static) releases are then provided in Canoeboot, based on specific coreboot revisions.
