coreboot 4.19 release
|
||
========================================================================
|
||
|
||
The 4.19 release was completed on the 16th of January 2023.
|
||
|
||
Since the last release, the coreboot project has merged over 1600
|
||
commits from over 150 authors. Of those authors, around 25 were
|
||
first-time committers to the coreboot project.
|
||
|
||
As always, we are very grateful to all of the contributors for helping
|
||
to keep the project going. The coreboot project is different from many
|
||
open source projects in that we need to keep constantly updating the
|
||
codebase to stay relevant with the latest processors and technologies.
|
||
It takes constant effort to just stay afloat, let alone improve the
|
||
codebase. Thank you very much to everyone who has contributed, both in
|
||
this release and in previous times.
|
||
|
||
The 4.20 release is planned for the 20th of April, 2023.
|
||
|
||
|
||
Significant or interesting changes
|
||
----------------------------------
|
||
|
||
|
||
### Show all Kconfig options in saved config file; compress same
|
||
|
||
The coreboot build system automatically adds a 'config' file to CBFS
|
||
that lists the exact Kconfig configuration that the image was built
|
||
with. This is useful to reproduce a build after the fact or to check
|
||
whether support for a specific feature is enabled in the image.
|
||
|
||
This file has been generated using the 'savedefconfig' Kconfig command,
|
||
which generates the minimal .config file that is needed to produce the
|
||
required config in a coreboot build. This is fine for reproduction, but
|
||
bad when you want to check if a certain config was enabled, since many
|
||
options get enabled by default or pulled in through another option's
|
||
'select' statement and thus don't show up in the defconfig.
|
||
|
||
Instead coreboot now includes a larger .config instead. In order to save
|
||
some space, all of the comments disabling options are removed from the
|
||
file, except for those included in the defconfig.
|
||
|
||
We can also LZMA compress the file since it is never read by firmware
|
||
itself and only intended for later re-extraction via cbfstool, which
|
||
always has LZMA support included.
|
||
|
||
|
||
### Toolchain updates
|
||
|
||
* Upgrade LLVM from 15.0.0 to 15.0.6
|
||
* Upgrade CMake from 3.24.2 to 3.25.0
|
||
* Upgrade IASL from 20220331 to 20221020
|
||
* Upgrade MPFR from 4.1.0 to 4.1.1
|
||
|
||
|
||
### Finished the conversion to ASL 2.0 syntax
|
||
|
||
Until recently, coreboot still contained lots of code using the legacy
|
||
ASL syntax. However, all ASL code was ported over to make use of the ASL
|
||
2.0 syntax and from this point on new ASL code should make use of it.
|
||
|
||
|
||
Additional coreboot changes
|
||
---------------------------
|
||
|
||
* Significant work was done to enable and build-test clang builds.
|
||
* Added touchscreen power sequencing and runtime detection.
|
||
* A number of patches were added to clean up and improve SMBIOS.
|
||
* Work is in progress to unify and extend coreboot post codes.
|
||
* Clean up for header includes is in progress with help from IWYU.
|
||
* IOAPIC code has been reworked.
|
||
* Support was added to superiotool for the NCT6687D-W chip.
|
||
* Work is progressing to switch return values to enum cb_err instead of
|
||
bool or other pass/fail indicators.
|
||
* Clang builds are now working for most boards and are being
|
||
build-tested.
|
||
* 64-bit coreboot support is in progress and is working on a number of
|
||
platforms.
|
||
* A driver for EC used on various Clevo laptops was added.
|
||
* Native Intel Lynxpoint code was added to replace the MRC.bin.
|
||
* Work continued for the process of adding ops structures to the
|
||
devicetree.
|
||
* The crossgcc tool can now download the source packages, which are
|
||
needed to build the coreboot toolchain, from coreboot’s own mirror if
|
||
desired.
|
||
* A document with useful external resources related to firmware
|
||
development was added at Documentation/external_docs.md.

Plans to move platform support to a branch
|
||
------------------------------------------
|
||
|
||
|
||
### Intel Icelake SoC & Icelake RVP mainboard
|
||
|
||
Intel Icelake is unmaintained and the only user of this platform ever
|
||
was the Intel CRB (Customer Reference Board). From the looks of the
|
||
code, it was never ready for production as only engineering sample
|
||
CPUIDs are supported.
|
||
|
||
Intel Icelake code will be removed following 4.19 and any maintenance
|
||
will be done on the 4.19 branch. This consists of the Intel Icelake SoC
|
||
and Intel Icelake RVP mainboard.
|
||
|
||
|
||
### Intel Quark SoC & Galileo mainboard
|
||
|
||
The SoC Intel Quark is unmaintained and different efforts to revive it
|
||
failed. Also, the only user of this platform ever was the Galileo
|
||
board.
|
||
|
||
Thus, to reduce the maintenance overhead for the community, support for
|
||
the following components will be removed from the master branch and will
|
||
be maintained on the release 4.20 branch.
|
||
|
||
* Intel Quark SoC
|
||
* Intel Galileo mainboard

||
