Upcoming release - coreboot 4.11
|
|
================================
|
|
|
|
The 4.11 release is planned for October 2019
|
|
|
|
Update this document with changes that should be in the release
|
|
notes.
|
|
* Please use Markdown.
|
|
* See the [4.9](coreboot-4.9-relnotes.md) and [4.10](coreboot-4.10-relnotes.md)
|
|
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.
|
|
|
|
Clean Up
|
|
--------
|
|
Because there was only a single developer board (AMD Torpedo)
|
|
using AGESA family 12h, and because there were multiple,
|
|
unique Coverity issues with it, the associated vendorcode will
|
|
be removed shortly after this release.
|
|
|
|
Significant changes
|
|
-------------------
|
|
|
|
### Add significant changes here
|
|
|
|
### `__PRE_RAM__` is deprecated
|
|
|
|
Preprocessor use of `defined(__PRE_RAM_)` have been mostly replaced with
|
|
`if (ENV_ROMSTAGE_OR_BEFORE)` or the inverse `if (ENV_RAMSTAGE)`.
|
|
|
|
The remaining cases and `-D__PRE_RAM__` are to be removed soon after release.
|
|
|
|
### `__BOOTBLOCK__` et.al. are converted
|
|
|
|
This applies to all `ENV_xxx` definitions found in `<rules.h>`.
|
|
|
|
Write code without preprocessor directives whenever possible, replacing
|
|
`#ifdef __BOOTBLOCK__` with `if (ENV_BOOTBLOCK)`
|
|
|
|
In cases where preprocessor is needed use `#if ENV_BOOTBLOCK` instead.
|
|
|
|
### `CAR_GLOBAL` is removed where possible
|
|
|
|
For all platform code with `NO_CAR_GLOBAL_MIGRATION=y`, any `CAR_GLOBAL`
|
|
attributes have been removed. Remaining cases from common code are to be
|
|
removed soon after release.
|
|
|
|
### `TSEG` and `cbmem_top()` mapping
|
|
|
|
Significant refactoring has bee done to achieve some consistency across platforms
|
|
and to reduce code duplication.
|
|
|
|
### Added VBOOT support to the following platforms:
|
|
* intel/gm45
|
|
* intel/nehalem
|
|
|
|
### Moved the following platforms to C_ENVIRONMENT_BOOTBLOCK:
|
|
* intel/gm45
|
|
* intel/nehalem
|
|
* intel/braswell
|
|
|
|
### Other
|
|
* Did cleanups around TSC timer
|
|
* Improved automatic VR configuration on SKL/KBL
|
|
* Filled additional fields in SMBIOS type 4
|
|
* Removed magic value replay from Intel Nehalem/ibexpeak code base
|
|
* Added OpenSBI on RISCV platforms
|
|
* Did more preparations for Intel TXT support
|
|
* Did more preparations for x86_64 stage support
|
