[coreboot] coreboot 24.12 release tag planned for 18.12!

[Felix Singer]

We are a quite late with the upcoming release this time, but we didn't
forget it. The tag is planned for December 18th.

Patches which should make it into the release are marked with the
hashtag

coreboot_release_2412

Patches which need to be merged afterwards (e.g. toolchain related) are
marked with the hashtag

coreboot_post_release_2412

As always, the final announcement will be done around one week later,
and this time during the 38th Chaos Communication Congress in Hamburg!
Hope to see you there :)

Felix
