@ -18,14 +18,17 @@ using AGESA family 12h, and because there were multiple,
unique Coverity issues with it, the associated vendorcode will
be removed shortly after this release.
Support for the MIPS architecture will also be removed shortly after
this release as the only board in the tree was a discontinued development
board and no other work has picked up MIPS support, so it's very likely
broken already.
Significant changes
-------------------
### Add significant changes here
### `__PRE_RAM__` is deprecated
Preprocessor use of `defined(__PRE_RAM_)` have been mostly replaced with
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.

Significant refactoring has bee done to achieve some consistency across platforms
and to reduce code duplication.
### Build system amenities ###
The build system now has an `all` class of source files to remove the need to
list source files for each and every source class (romstage, ramstage, ...)
The site-local/ mechanism became more robust.
### Stricter coding standards to improve security ###
The build now fails on variable length arrays (that make it way too easy to
smash a stack) and case statements falling through without a note that it is
intentional.
### Shorter file headers ###
This project is still under way, but we started moving author information
from individual files into the global AUTHORS file (and there's the git
history for more details).
In the future, we also want to replace the license headers (lots of lines)
in each file with spdx identifiers (one line) and so we added a LICENSES/
directory that contains the full text of all the licenses that are used
throughout our tree.
### Variant creation scripts ###
To ease the creation of variant boards, `util/mainboard/` now contains
scripts to generate a new variant to a given board. These are still
specific to google/hatch at this time, but they're written with the idea
of becoming more generally useful.
### Payloads ###
Payload integration has been updated, coreinfo learned to cope with
UPPER CASE commands and libpayload knows how to deal with USB3 hubs.
### Added VBOOT support to the following platforms:
* intel/gm45
* intel/nehalem
