| coreboot 4.9 release notes
 | |
| ==========================
 | |
| 
 | |
| The 4.9 release covers commit 532b8d5f25 to commit 7f520c8fe6
 | |
| There is a pgp signed 4.9 tag in the git repository, and a branch will
 | |
| be created as needed.
 | |
| 
 | |
| In the little more than 7 months since 4.8.1 we had 175 authors commit
 | |
| 2610 changes to master. The changes were, for the most part, all over
 | |
| the place, touching every part of the repository: chipsets, mainboards,
 | |
| tools, build system, documentation.
 | |
| 
 | |
| In that time we also had 70 authors made their first commit to coreboot:
 | |
| Welcome and to many more!
 | |
| 
 | |
| Finally, a big Thank You to all contributors who helped shape the
 | |
| coreboot project, community and code with their effort, no matter if
 | |
| through development, review, testing, documentation or by helping people
 | |
| asking questions on our venues like IRC or our mailing list.
 | |
| 
 | |
| Clean up
 | |
| --------
 | |
| If there's any topic to give to this release, "clean up" might be the
 | |
| most appropriate: There was lots of effort to bring the codebase into
 | |
| compliance with our coding style, to remove old idioms that we'd like
 | |
| to retire like the overloaded `device_t` data type, and to let features
 | |
| percolate through the entire tree to bring more uniformity to its parts.
 | |
| 
 | |
| For example, during the coreboot 4.4 cycle, coreboot gained the notion
 | |
| of mainboard variants to avoid duplication of code in rather similar
 | |
| mainboards.
 | |
| 
 | |
| Back then, this feature was developed and used mostly for the benefit
 | |
| of Chrome OS devices, but more recently the code for various Lenovo
 | |
| Thinkpads was deduplicated in the same way.
 | |
| 
 | |
| Another part of cleaning up our tree is improving our tools that help
 | |
| developers follow coding style and avoid mistakes, as well as the
 | |
| infrastructure we have for automated build tests and we've seen quite
 | |
| some activity in that space as well.
 | |
| 
 | |
| Documentation
 | |
| -------------
 | |
| Since the last release we also moved the documentation into the
 | |
| repository. No need for a special wiki account to edit the documentation,
 | |
| and by colocating sources and documentation, it's easier to keep the
 | |
| latter in sync with the code, too.
 | |
| 
 | |
| This effort is still under way, which is why we still host the old wiki (now
 | |
| read-only) in parallel to the [new documentation
 | |
| site](https://doc.coreboot.org) that is rendered from coreboot.git's
 | |
| Documentation/ directory.
 | |
| 
 | |
| Blobs handling
 | |
| --------------
 | |
| Another big change is in our blobs handling: Given that Intel now
 | |
| provides a reasonably licensed repository with FSP binaries, we were
 | |
| able to mirror it to coreboot.org and integrate it in the build system.
 | |
| This makes it easier to have working images out of the box for devices
 | |
| that depend on Intel's proprietary init code.
 | |
| 
 | |
| As usual the blobs aren't part of the coreboot tree and only downloaded
 | |
| with the `USE_BLOBS` options.
 | |
| 
 | |
| Deprecations
 | |
| ------------
 | |
| One of the first changes to coreboot after the 4.8 release was to remove
 | |
| boards that didn't support certain new features and were apparently
 | |
| unmaintained, as discussed in the release notes of coreboot 4.6.
 | |
| 
 | |
| We didn't follow up on all plans made back then to deprecate boards more
 | |
| aggressively: The board status reporting mechanism is still rather raw
 | |
| and therefore places quite a burden on otherwise sympathetic contributors
 | |
| of build results.
 | |
| 
 | |
| Also, there will be no deprecations after 4.10: Due to its slipping
 | |
| schedule, coreboot 4.9 is released rather late, and as a result 4.10
 | |
| will only see about 4 months of development. We considered that a rather
 | |
| short timeframe in which to bring old boards up to new standards, and
 | |
| so the next deprecation cycle may be announced with 4.10 to occur after
 | |
| 4.11 is released, in late 2019.
 | |
| 
 | |
| General changes
 | |
| ---------------
 | |
| * Various code cleanups
 | |
|   * Removed `device_t` in favor of `struct device*` in ramstage code
 | |
|   * Removed unnecessary include directives
 | |
|   * Improved adherence to coding style
 | |
|   * Deduplicated boards by using the variants mechanism
 | |
| * Expand use of the postcar stage
 | |
| * Add bootblock compression capability: on systems that copy the bootblock
 | |
|   from very slow flash to SRAM, allow adding a stub that decompresses the
 | |
|   bootblock into SRAM to minimize the amount of flash reads
 | |
| * Rename the POWER8 architecture port to PPC64 to reflect that it isn't limited
 | |
|   to POWER8
 | |
| * Added support for booting FIT (uImage) payloads on arm64
 | |
| * Added SPI flash write protection API
 | |
|   * Implemented on Winbond
 | |
| * Implemented TCPA log for measured boot
 | |
| * Implemented GDB support for arm64 architecture in libpayload
 | |
| * Dropped support for unmaintained code paths
 | |
| * Measured boot support
 | |
| 
 | |
| Added 56 mainboards
