Darren's the right person to give a proper summary, since
he was driving our beagleboard work. But he's out on Jury
duty at the moment, so we'll have to wait. I can attempt
a quick summary here.

The goal of a BSP like this as part of meta-yocto and linux-yocto
are this for any BSP:

Goals:
1) <vendor/semi> needs meta-<vendor/semi> to maintain its role
    as the definitive source for <vendor/semi> BSPs and drive 
fragmentation down.
2) The Yocto Project meta-yocto layer has a goal to provide
    stand-alone BSPs that demonstrates the multi-architecture
    features of the Yocto Project.

To to this, we have the challenges:

A) Using meta-<vendor/semi> with the Yocto Project
B) Aligning on kernel versions
C) Kernel policy definition and ownership
D) Not detract from upstream-first efforts
.. and more.

So the meta-<foo> issues will be solved going forward with
layer tooling, the kernel version alignment will never
be solved completely but can be addressed via working with
the right upstream and sources with the right process.

So to get that kernel alignment, tooling, common feature set
and have a set of BSPs that can share tests, results, support,
etc, there is a need to do yocto integrations of identified
BSPs. We've (largely) agreed to live with some repeated effort
in the short term and recognize that what you see here is
not intended to replace a community or vendor effort, but
should be considered as a stepping stone and proof of
concept. If the latest and greatest, bleeding edge is what
people want, then the other meta-* layers are the way to go.

I think that's enough for now, I tried to do the conversations
justice and keep this short, so my apologies to anyone reading
this if I missed something.

Cheers,

Bruce
