A BSP layer shouldn't be deciding to include all kernel modules. That's more
of a distro decision, or for local.conf at a minimum. Modules that are
required for the basic functioning of a board are fine, but doing a blanket
"install all" is overreach and inflates images unnecessarily (~45MB, by one
measurement).

I expect patches will probably roll in after this one to add back necessary
modules, but it will be easier to figure out which ones when starting with
having none of them included by default.

It's only a RRECOMMENDS, so I'd say this is fine as is? This allows to have a working system without spending too much time figuring out what's exactly needed. If someone needs to have a smaller image, they can then play with kernel defconfig or kernel-modules- in packages to install.

Up to you though :)

Cheers,
Quentin

Yeah on one thought, BSP users may not be well versed in OE speak and
this adds to their bad starting experience but it also has a bad
effect where the images are bloated. So IMO if it is well documented
how to enable/disable it easily could be useful. I don't have strong
leanings
on which way you want to go w.r.t defaults.
