Upcoming release - coreboot 4.18
================================
The 4.18 release is planned for August 2022.
Update this document with changes that should be in the release notes.
* Please use Markdown.
* See the past few release notes for the general format.
* The chip and board additions and removals will be updated right
before the release, so those do not need to be added.
Significant changes
-------------------
### Add significant changes here
Plans for Code Deprecation
--------------------------
### Intel Icelake
Intel Icelake code will be removed following the 4.19 release, planned
for November 2022. This consists of the Intel Icelake SOC and Intel
Icelake RVP mainboard
Intel Icelake is unmaintained. Also, the only user of this platform ever
was the CRB board. From the looks of it the code never was ready for
production as only engineering sample CPUIDs are supported. This reduces
the maintanence overhead for the coreboot project.
### LEGACY_SMP_INIT
Legacy SMP init will be removed from the coreboot master branch
immediately following this release. Anyone looking for the latest
version of the code should find it on the 4.18 branch.
This also includes the codepath for SMM_ASEG. This code is used to start
APs and do some feature programming on each AP, but also set up SMM.
This has largely been superseded by PARALLEL_MP, which should be able to
cover all use cases of LEGACY_SMP_INIT, with little code changes. The
reason for deprecation is that having 2 codepaths to do the virtually
the same increases maintenance burden on the community a lot, while also
being rather confusing.
