[coreboot] chat.coreboot.org is on

[Patrick Georgi]

Hi all,

we've set up a mattermost instance on https://chat.coreboot.org/ in the 
hope to lower the barriers to entry into our community.

It comes with a bridge to IRC, history (but not web-indexable, which was 
a major concern with IRC logs so far) and the ability to start topic 
channels that are discoverable yet separate from the main discussion.

See you there,
Patrick
