[coreboot] PSA: abandoning old patches (again)

[Stefan Reinauer]

Hi,

we're planning (as we have done in the past), to abandon patches that
have been crowding up gerrit without any update in the last 18 months.

The list of patches in question is
https://review.coreboot.org/#/q/status:open+age:18months

If you want to preserve any of those patches, please rebase them against
current ToT, take them over, maintain them, or whatever, because I plan
to abandon everything that is still in this list at the end of next week
(November 4th)

Stefan
