Embedded Base Boot Requirements (EBBR) specification
The Embedded Base Boot Requirements specification defines requirements for embedded systems to enable inter-operability between SoCs, hardware platforms, firmware implementations, and operating system distributions. The aim is to establish consistent boot ABIs and behaviour so that supporting new hardware platforms does not require custom engineering work.
The first formal v1.0 release of EBBR was made in March 2019. You can find the current draft text in this repository, but be aware that everything in the draft text is subject to change. Official pdfs can be found in the "Releases" tab of this GitHub project.
Released EBBR PDFs can be found here:

Anyone may contribute to EBBR. Discussion is on the [email protected] mailing list, and there is a weekly conference call. See CONTRIBUTING.rst for details.
