[PATCH] add basic b4 config file

[Quentin Schulz]

From: Quentin Schulz <quentin.schulz@cherry.de>

b4[1] is a very nice tool for mail-based contribution. A config[2] file
exists to set up a few defaults. We can use it to set the To recipients
to always add, in our case the mailing list.

This shouldn't be necessary if we had a script that b4 prep --auto-to-cc
could call to find the mail address(es) to send to, à-la
scripts/get_maintainer.pl from the kernel tree.

This allows us to not have to look for the mailing list to send the
patches to, just use b4 and you're all set.

Since that ML is also used for other repos than v4l-utils and I've seen
a few people using [v4l-utils] as prefixes, should we add

send-prefixes = v4l-utils

to the config file as well?

Yes please.

I'm not sure I want to have this in v4l-utils, but if I do, then definitely with
that prefix.

When you post the new patch, please prefix it with v4l-utils as well.

I believe we prefer send-series-cc.

[PATCH] add basic b4 config file

[Quentin Schulz]

From: Quentin Schulz <quentin.schulz@cherry.de>

b4[1] is a very nice tool for mail-based contribution. A config[2] file
exists to set up a few defaults. We can use it to set the Cc recipients
to always add, in our case the mailing list.

Because we do not have anything to check for now, disable needs-checking
so patches can be sent without running b4 prep --check.

Because we do not have any auto-to-cc support (and the implicit one
using scripts/get_maintainer.pl cannot work for us), also disable
needs-auto-to-cc so patches can be sent without running b4 prep
--auto-to-cc.

I'm wondering if we couldn't add some per-patch check as well, checking
that the documentation builds for each for example. Could be added in a
later patch though. Any idea?

Note that this file should be overridden by the one that I'll send for
poky by the merging script (no clue how that would work), i.e. an update
of .b4-config from OE-Core should not override the one from poky OE-Core
when we merge/cherry-pick OE-Core patches later on.

Support b4 for easier contribution workflow.

Note that this should be backportable as is to earlier releases.

Additionally, we may want to add:

send-prefixes = <insert release name>

in earlier release branches so that one doesn't even have to think about
adding the branch name when writing patches for older releases (added
bonus is that the maintainers would then know if someone has sent
patches developed on earlier releases instead of targeting master :) ).

This shouldn't be necessary if we had a script that b4 prep --auto-to-cc
could call to find the mail address(es) to send to. While we could do
that, this opens the door to people trying to add a way to notify some
people (e.g. a MAINTAINERS file) which is not somewhere the project
wants to go right now, and this also makes sure the address is always
added even if one forgets to run b4 prep --auto-to-cc (which is part of
the typical workflow for U-Boot and Linux kernel, but is not necessary
thanks to this patch).

This adds a basic config file for b4 to avoid to have to add the mailing
list by hand. For documentation patches, one will still need to run
b4 send --cc docs@lists.yoctoproject.org
manually for sending it to the docs ML as well.

Note that b4 supports patchwork, c.f.
https://b4.docs.kernel.org/en/latest/config.html#patchwork-integration-settings
though I have no clue what it does with it as I am no maintainer, but
maybe something worth having a look at if some maintainer of this repo
wants to use b4 to merge stuff?
