This page collects sweeping changes on the tree that might have an impact on boards that weren't tested by the developer, or on uncommitted development. It's sorted by date and provides a Changelog to anyone who needs to update older trees.

The CBFS master header used to denote the alignment of files within the CBFS image. This is now hard coded to 64 bytes, which was already the default. The master header format didn't change and the field continues to be set to 64, so old code will continue to work with new images. New code will work with old images as long as their alignment is set to 64 bytes.
2015-09-09: commit 6aa8c5bc
CONFIG_DRIVERS_PS2_KEYBOARD defaults to false now, which means that coreboot doesn't initialize PS/2 keyboards anymore (unless specifically requested). Payloads need to adapt if they can't to initialization on their own (or have it disabled under the assumption that coreboot provided for that).
