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
* Added SSDT generator for arbitrary SuperIO chips based on devicetree.cb
