4.20 release preparations

[Felix Singer]

Hi everyone,

2 months passed since last release and the 4.20 release is ahead of us.

I'm starting with the release preparations on Monday, which means I'm
going through the patches on Gerrit (also the merged ones) and see what
could add some value to the release and what needs more documentation.

Patches, which should be included in the release, are marked with the
following hashtag:

coreboot_release_4.20

Patches lacking of documentation (no matter if release notes, user or
developer documentation), are marked with the following hashtag:

coreboot_needs_documentation

Hashtags can be added by everyone, but the field for that is a little
bit hidden. Once you have a patch open, click on "Show all" in the top
left corner and then the hashtag field shows up in the list.

Please feel free to add any of these hashtags yourself. In addition to
that, add at least me to the reviewer list so that I'm getting notified
and aware of it.

If you add the hashtag for missing documentation, also add a comment
about what exactly is missing.

I will try to summarize the status at the end of each week.

Felix
