Introduction
|
|
============
|
|
|
|
[Libreboot 20211122](libreboot20211122.md) was the last release to officially
|
|
support these boards: ASUS KFSN4-DRE, KCMA-D8 and KGPE-D16; they were removed
|
|
much later, in subsequent releases.
|
|
|
|
I'm pleased to announce that they have, today, been re-added to `lbmk.git`.
|
|
This is the [automated build system](../docs/maintain/) that builds Libreboot
|
|
ROM images, and Libreboot releases, ready for installation.
|
|
|
|
These boards are available *now*, if you're willing to [build Libreboot from
|
|
source](../docs/build/); otherwise, you will find them in the next regular
|
|
release of Libreboot.
|
|
|
|
It was implemented with this patch:
|
|
<https://browse.libreboot.org/lbmk.git/commit/?id=af084014f04602f570a23b0cc23a112401348faf>

Differences now, versus Libreboot 20211122
|
|
------------------------------------------
|
|
|
|
The following changes have been made, relative to Libreboot 20211122:
|
|
|
|
* Coreboot `4.11_branch` (branch) used, instead of regular `4.11` (release tag).
|
|
This contains many fixes on top of the original Coreboot 4.11 release that
|
|
Libreboot used.
|
|
* I fixed several errors, enabling coreboot's crossgcc toolchain compilers
|
|
from `4.11_branch` to *build* properly, on modern distros; Debian Sid was
|
|
tested, and Arch Linux should work too. Without these patches, it would not
|
|
build at all.
|
|
* Fixed downloading of `acpica` (for use of `iasl`) in the coreboot crossgcc
|
|
build script; the upstream link for tarballs of `acpica` were no longer
|
|
online. Coreboot switched to github in newer revisions, but this older one
|
|
needed patching. I ended up hosting the relevant tarball *myself*, on
|
|
Libreboot rsync. The mirrors now have it, and Libreboot's modified
|
|
coreboot `4.11_branch` uses that.
|
|
* Libreboot's build system (`lbmk.git`) has been modified, to make it avoid
|
|
building GCC Gnat, in crossgcc from coreboot `4.11_branch`. Coreboot
|
|
implements video initialisation in *Ada* on many platforms, but these AMD
|
|
boards use AST (Aspeed) framebuffer chips, where coreboot video initialisation
|
|
is written in normal C. This avoids having to deal with build issues, when
|
|
[building older Gnat with newer host
|
|
Gnat](https://gcc.gnu.org/install/prerequisites.html)
|
|
|
|
The PIKE2008 fix from Libreboot 20211122 was retained, and it is included in
|
|
today's change. This inserts an empty option ROM in CBFS, without which SeaBIOS
|
|
would hang; the empty option ROM prevents SeaBIOS from loading the real one.
|
|
|
|
Dasharo firmware
|
|
----------------
|
|
|
|
**Libreboot does not yet integrate Dasharo.**
|
|
|
|
Dasharo has support for ASUS KGPE-D16 on a much newer version of coreboot,
|
|
where *upstream* coreboot had deleted KFSN4-DRE/KCMA-D8/KGPE-D16 support just
|
|
after the 4.11 release; however, Dasharo *only* supports KGPE-D16 (out of these
|
|
boards).
|
|
|
|
I intend to study code differences between D8/D16 in time, and port those to
|
|
Dasharo so that it can have a KCMA-D8 port. I then wish to use this in
|
|
Libreboot. I *could* use Dasharo now, for D16, regardless. For now, the main
|
|
priority is to have support for these boards again in Libreboot.
|
|
|
|
The previous news announcement said that I would only add these boards after
|
|
doing that, but I felt this work is worthy enough for entry in the main branch
|
|
of Libreboot. Any issues that it has will be similar to what was present in the
|
|
Libreboot 20211122 release (Dasharo made a lot of improvements, especially to
|
|
raminit).
|
|
|
|
I would like it if people can provide testing for all of these boards, in
|
|
today's Libreboot's revisions. [Learn here how to become a board tester for
|
|
