Vincent Zimmer of Intel UEFI has posted TWO blog posts, to catch up to.
In the first, he point out some newly-released Intel FSP 2.0 documents:

https://firmware.intel.com/develop
In the second, he talks about UEFI history, focused on the 2 editions of the Beyond BIOS book (and the recent UEFI reference book in comic book pop culture).

PS: Intel Press, the web pages (including errata) for the Beyond BIOS 2nd Edition and UEFI Shell books are broken. It sucks to have an $80 book with a broken web site. Nothing personal, it seems most tech book publishers are terrible at persistant web sites and ‘cool URIs’. 😦
