1coreboot 4.19 release
2========================================================================
3
4The 4.19 release was completed on the 16th of January 2023.
5
6Since the last release, the coreboot project has merged over 1600
7commits from over 150 authors. Of those authors, around 25 were
8first-time committers to the coreboot project.
9
10As always, we are very grateful to all of the contributors for helping
11to keep the project going. The coreboot project is different from many
12open source projects in that we need to keep constantly updating the
13codebase to stay relevant with the latest processors and technologies.
14It takes constant effort to just stay afloat, let alone improve the
15codebase. Thank you very much to everyone who has contributed, both in
16this release and in previous times.
17
18Note that the first set of tarballs posted for the 4.19 release had
19bad timestamps. This has been fixed. Hashes for all tarballs are at
20the bottom of this document.
21
22The 4.20 release is planned for the 20th of April, 2023.

25Significant or interesting changes
26----------------------------------
27
28
29### Show all Kconfig options in saved config file; compress same
30
31The coreboot build system automatically adds a 'config' file to CBFS
32that lists the exact Kconfig configuration that the image was built
33with. This is useful to reproduce a build after the fact or to check
34whether support for a specific feature is enabled in the image.
35
36This file has been generated using the 'savedefconfig' Kconfig command,
37which generates the minimal .config file that is needed to produce the
38required config in a coreboot build. This is fine for reproduction, but
39bad when you want to check if a certain config was enabled, since many
40options get enabled by default or pulled in through another option's
41'select' statement and thus don't show up in the defconfig.
42
43Instead coreboot now includes a larger .config instead. In order to save
44some space, all of the comments disabling options are removed from the
45file, except for those included in the defconfig.
46
47We can also LZMA compress the file since it is never read by firmware
48itself and only intended for later re-extraction via cbfstool, which
49always has LZMA support included.
50
51
52### Toolchain updates
53
54* Upgrade LLVM from 15.0.0 to 15.0.6
55* Upgrade CMake from 3.24.2 to 3.25.0
56* Upgrade IASL from 20220331 to 20221020
57* Upgrade MPFR from 4.1.0 to 4.1.1
58
59
60### Finished the conversion to ASL 2.0 syntax
61
62Until recently, coreboot still contained lots of code using the legacy
63ASL syntax. However, all ASL code was ported over to make use of the ASL
642.0 syntax and from this point on new ASL code should make use of it.
65
66
67Additional coreboot changes
68---------------------------
69
70* Significant work was done to enable and build-test clang builds.
71* Added touchscreen power sequencing and runtime detection.
72* A number of patches were added to clean up and improve SMBIOS.
73* Work is in progress to unify and extend coreboot post codes.
74* Clean up for header includes is in progress with help from IWYU.
75* IOAPIC code has been reworked.
76* Support was added to superiotool for the NCT6687D-W chip.
77* Work is progressing to switch return values to enum cb_err instead of
78  bool or other pass/fail indicators.
79* Clang builds are now working for most boards and are being
80  build-tested.
81* 64-bit coreboot support is in progress and is working on a number of
82  platforms.
83* A driver for EC used on various Clevo laptops was added.
84* Native Intel Lynxpoint code was added to replace the MRC.bin.
85* Work continued for the process of adding ops structures to the
86  devicetree.
87* The crossgcc tool can now download the source packages, which are
88  needed to build the coreboot toolchain, from coreboot’s own mirror if
89  desired.
90* A document with useful external resources related to firmware
91  development was added at Documentation/external_docs.md.

177Plans to move platform support to a branch
178------------------------------------------
179
180
181### Intel Icelake SoC & Icelake RVP mainboard
182
183Intel Icelake is unmaintained and the only user of this platform ever
184was the Intel CRB (Customer Reference Board). From the looks of the
185code, it was never ready for production as only engineering sample
186CPUIDs are supported.
187
188Intel Icelake code will be removed following 4.19 and any maintenance
189will be done on the 4.19 branch. This consists of the Intel Icelake SoC
190and Intel Icelake RVP mainboard.
191
192
193### Intel Quark SoC & Galileo mainboard
194
195The SoC Intel Quark is unmaintained and different efforts to revive it
196failed. Also, the only user of this platform ever was the Galileo
197board.
198
199Thus, to reduce the maintenance overhead for the community, support for
200the following components will be removed from the master branch and will
201be maintained on the release 4.20 branch.
202
203  * Intel Quark SoC
204  * Intel Galileo mainboard
