Leah Rowe cc82b733d3 tree.sh: Place target builds under tree/target/
as opposed to target/

for example:

image the command:

./mk -b u-boot amd64coreboot

This would put the U-Boot binaries here:
elf/u-boot/amd64coreboot/default/

With this change, they now go here:

elf/u-boot/x86_64/amd64coreboot/default/

This solves a problem that existed previously, where
you could modify a given tree in a multi-tree project,
but cached builds for targets branching separately off
of each tree would not be deleted, and thus not re-built.

This accomplishes such a result, without needing to
further check hashes of individual targets.

The latter will still be done, in a future change, because
this change doesn't fix another problem:

If you change a given config, e.g. targetname "foo" which
uses tree "bar", elf/foo/ would not be removed automatically
for re-build.

So this change only deletes individual target builds when
their master tree changes.

Where the target and tree are the same, this also means
elf/tree/target/

for example: seabios/default would create binaries in:

elf/seabios/default/default/

not:

elf/seabios/default/

Libreboot

Documentation: libreboot.org
Support: #libreboot on Libera IRC

Libreboot provides libre boot firmware on supported motherboards. It replaces proprietary vendor BIOS/UEFI implementations, by

  • Using coreboot to initialize the hardware (e.g. memory controller, CPU, etc.) while minimizing unwanted functionality (e.g. backdoors such as the Intel Management Engine)
  • ... which runs a payload such as SeaBIOS, GRUB, or U-Boot
  • ... which loads your operating system's boot loader (BSD and Linux-based systems are supported).

Why use Libreboot, and what is coreboot?

A lot of users who use libre operating systems still use proprietary boot firmware, which often contain backdoors and bugs, hampering user freedom and right to repair.

coreboot provides libre boot firmware by initializing the hardware then running a payload. However, coreboot is notoriously difficult to configure and install for most non-technical users, requiring detailed technical knowledge of hardware.

Libreboot solves this by being a coreboot distribution (in the same way that Alpine Linux is a Linux distribution). It provides a fully automated build system that downloads and compiles pre-configured ROM images for supported motherboards, so end-users could easily fetch images to flash onto their devices.

Libreboot also produces documentation aimed at non-technical users and excellent user support via IRC.

Contribute

You can check bugs listed on the bug tracker.

You may use Codeberg pull requests to send patches with bug fixes or other improvements. This repository hosts the code for the main build system. The website lives in a separate repository.

Development is also done on the IRC channel.
