I would use this, so:
Acked-by: Linus Walleij <linus.walleij@...aro.org>

I hacked up fragments for using Arch Linux and I believe OpenWRT
could use fragments like this as well.

I think we should discuss feature splitting of the config fragments.

What is complicated with configs is finding the right kernel features
for the userspace you are doing. At one point, I don't remember where
or when, it was discussed adding a systemd config fragment, as it
is using a slew of non-optional kernel config options. Then other
distros using that could simply use that fragment to get it right.
I'm pretty sure the systemd deps are a subset of the Fedora config
for example.

I would think similar fragments could be good for e.g. wireless
networking, USB storage and such things where I for one found
it really annoying having to spend time finding the right Kconfig to
just get that rolling reasonably.

Yours,
Linus Walleij
