I am always sad to see boards go away, especially since it means that the amount of coreboot I still have code in is smaller by the month, but ... there's a real opportunity cost to keeping old boards in. We've had cases where a new, useful feature has to be implemented as a config variable since not all boards can support it. Frequently these are old boards and there's nobody around to add it. Further, experience has shown us that over time, even if nothing else changes, older boards just stop working due to toolchain changes or even bug fixes. I've had this happen to me several times, where I can't build a new image for a board that is "known good." I'm not the only one.

It's a lot of work to keep a board current. We don't want coreboot to become a repo of broken boards. If nobody can stand up and state they are supporting a board, then it's time to end that board. And, as pointed out, this is git, there are branches, so no board is ever really gone.

I think that for every board in the tip of tree, we should always have an active maintainer. It's just too easy for them to break otherwise.

Keep in mind that branches exist for each release which inherently has
the full history at time of release:
