v2.3.0

This is a minor release of the EBBR specification.

Compared to v2.2.0, this release formalizes the Boot Manager requirements, adds requirements on authenticated FMP capsules for firmware update and deprecates spin tables for AArch64.

Changes since v2.2.0:

• Formalize the Boot Manager requirements
• Require authenticated FMP capsules for firmware update
• Deprecate spin tables for AArch64
• Add conformance profile GUID for version 2.3
• Remove ambiguities around the collation protocol
• Bump UEFI, PSCI, SMCCC, BBR and dt-schema references versions
• Move some footnotes around

• ebbr-v2.3.0-pre1.zip contains the pre-release artifacts.
• PDFC.-.ebbr-v2.2.0.pdf.-.ebbr-v2.3.0-pre1.pdf is a pdf comparison with v2.2.0.
• PDFC.-.ebbr-v2.2.0.pdf.-.ebbr.pdf is an additional pdf comparison with v2.2.0 but with an EBBR version generated locally (hence the "-dirty") to remove the watermark for convenience.

v2.2.0

This is a minor release of the EBBR specification.

Compared to v2.1.0, this release adds requirements on capsule update "on disk" variables and TPM, relaxes requirements on the monotonic counter, clarifies requirements on ConnectController and defines a file format for storing EFI variables.

v2.2.0-pre1

v2.2.0-pre1 prerelease for review

v2.1.0

This is a minor release of the EBBR specification.

Compared to v2.0.1, this release adds requirements on ESRT, EFI Conformance Profile and DTB, and updates the RISC-V boot requirements.

v2.1.0-pre1

v2.1.0-pre1 prerelease for review

v2.0.1

This is a point update to EBBR spec.

This update fixes some typos and relaxes the requirement for
implementing ESRT. The ESRT relaxation is temporary due to released
software not yet being able to meet the requirement. Mainline U-Boot has
already fixed most of the issues so that ESRT can be reintroduced in the
next minor or major release.

This release also merges in requirements for RISC-V platforms which had
been discussed on the mailing list for some time now. It is safe to
merge in this point release as it doesn't affect requirements on other
architectures.
