It is mentioned in version 1.2B of the PI specification, released 2010.
yep, and when I visited google in 2003, somebody mentioned the name HOB to me and then said "oops, don't repeat that name". So for half of its life, the name "HOB" was NDA.
The specifications used to be hidden behind a click-through license. I think it was 2013 that we managed to get that removed.
so 15 years in, we got past that limit. By then it was far too late. The design was locked down by that point, with all its mistakes wired in.
It's 23 years now, and for something we hope to use for the next 23 years, we can do better.
Even device tree would be far better.
I'd rather not take HOB as a given without considering alternatives. It's a very 1990s design.
