[coreboot] coreboot 4.9 release scheduled for Dec 20th

[Patrick Georgi]

Hi everybody,

just a friendly reminder that I plan to do the coreboot 4.9 release on Dec
20th, which is

next Thursday!

Please test master, report or fix issues and be considerate with what
you're merging (ie. maybe don't land the Rewrite Of Everything before the
release). I'd like to avoid the need to spin a 4.9.1 release :-)

Also take a look at the tentative release notes at
https://piratenpad.de/p/S8slYOeag and add the changes of the last ~8 months
that you think warrant a shout-out.

Thanks,
Patrick
