This reduces the data handoff friction and proprietary handoff formats currently exist in each and every firmware project (e.g. HOB, coreboot table).

Since its introduction, Intel has been actively seeking for the firmware community's input to help make it a reality, to help standardise a common architecture and interfaces between Platform Init and Payload. Later on, 9elements actively collaborated with Intel to work with all major firmware projects (coreboot, U-Boot, edk2, Linuxboot) with the support of all architecture (x86, Arm, RISC-V). We have been actively promoting and collecting feedback in every means we could (mailing lists, OSFC, OCP Global Summit, COSCUP). I could not find words to summarize the 2 years tireless efforts made by all the UPL contributors: with about 2-4 meetings per month since May 2022; countless back and forth discussion and some compromises made in between to find common ground that fits all Firmware solutions and projects; some technical setbacks with failed POCs and then persistent testings on coding sites; new expectations and issues pop up now and there that setback the initial timeline again and again... I owe all of them my greatest gratitude for their hard work. I would like to specially thanks Vincent Zimmer from Intel for making this happen in the first place - early commitment from ARM, Intel/ edk2 / Slimbootloaders maintainers, Chasel Chiu and Dong Guo, Maximilian Brune and Arther Heymans from coreboot, Dhaval Sharma and Aaron Durbin from Rivos, and Simon Glass & Ron Minnich who are both great visionaries in the Open Firmware world. In short, this is truly the first ever community effort that brings all firmware communities to collaborate together, in the very common goal to make Open Source Firmware a better place for everyone.

Hence, I sincerely pledge to all of you, to help and contribute to this spec. This is an open invitation, as we follow the ethos of "For Community, By Community", the first open source spec that is owned by all the open firmware communities.
