coreboot 4.9 release notes

The 4.9 release is planned for November 2018

Update this document with changes that should be in the release notes.

• Please use Markdown.
• See the 4.7 and 4.8 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.

General changes

• Various code cleanups
• Removed device_t in favor of struct device* in ramstage code
• Improve adherence to coding style
• Expand use of the postcar stage
• Add bootblock compression capability: on systems that copy the bootblock from very slow flash to ERAM, allow adding a stub that decompresses the bootblock into ERAM to minimize the amount of flash reads

Toolchain

• Update IASL to version 10280531
