I was thinking that instead of keying off of ARAGO_BRAND=mainline, which

PREFERRED_PROVIDER_virtual/kernel=linux-ti-mainline, that is specific to

We'd want mainline kernel, u-boot, tf-a, optee ..... as many upstream
components as possible. is there a way to create a virtual package group
that points to all upstream base components?
I am looking for ways we can enable this beyond just arago brand.
My understanding is that tf-a and optee were initially forked for K3
development, but these days are pretty much the same as upstream.
And optee is already pulling code from upstream, just pinning down to a
specific version and doing some extra TI-specific signing on top.
As of tf-a, I'd recommend dropping git.ti.com fork completely and pulling
from upstream, if possible.
Great minds.., 26998f43 :)

But kernel/U-boot is a bit more involved. Those are done as multiple
providers and require switching corresponding PREFERRED_PROVIDER
variables.
Either way, for testing which kernel is being built (ti-staging or mainline)
and which U-boot (ti-staging or mainline), checking PREFERRED_PROVIDER
should be doable and Distro-agnostic.
As of creating a virtual package group, it might be a bit challenging.
Since if you try building linux-ti-mainline w/o switching preferred provider,
you'd get an error saying there's a conflict between 2 kernels.
It would be more involved to solve this w/o simply switching providers,
maybe with multiconfig, or something like that...
