Libreboot 20220710 Released As Coreboot Downstream Focused On Boot Firmware Freedom
Libreboot 20220710 is the project's first new stable release since November. While much time has passed, this is just a bug-fix release and doesn't introduce any major new features. There is though lots of documentation improvements, performance improvements to the grub.cfg handling, disabling PECI to workaround issues with old GM45/ICH9M laptops, build system improvements, disabling by default serial output on all motherboards to prevent boot speed issues, enabling USB keyboards for the GRUB configuration, initial U-Boot integration to be used by boards in the future, updating to a newer Flashrom, and various other fixes.
The hardware compatibility page for Libreboot notes a variety of old Apple MacBooks and Lenovo ThinkPads as being supported, old AMD Opteron motherboards, and a few old Intel desktop motherboards from around 2009.
More details on the changes for this weekend's Libreboot stable update can be found on Libreboot.org.
Moving forward their road-map goals include adding support for non-x86 platforms, exploring a Linux distro in flash memory, re-factoring/optimizing the GRUB bootloader, and merging of OSboot and Libreboot code.
