I can add a few thoughts.

We obviously have the reference BSPs to represent the major architectures, and
on the linux-yocto mailing list, we've been looking at BSPs from LSI as well as
some other pending boards (I'm waiting on them to be submitted, so I
won't mention
them here). The xilinx boards also have some yocto-style support in
their repository
with us working to adopt and integrated version of them as we move
into Yocto 1.6+.

It's generally a slow process to get kernel versions aligned, but with
the LF LTSI
kernel(s), it helps create a neutral version that the Yocto project,
OSVs, semis and
others can use as a synchronization point. LTSI is part of the
linux-yocto kernel
trees as an integrated baseline, and LTSI has recently picked up more
attention ..
which has a byproduct of more BSPs being available in a similar
format, version and
configuration.

Obviously we'd also love to see all relevant BSPs completely
mainlined, with short
stays in the Yocto tree (or others) as a BSP is developed, stabilized
and eventually
upstreamed.

There's obviously a place for cutting edge trees, semi trees for the
latest and greatest,
stable trees .. and integrated staging grounds for all of the above.
So navigating that
mix, takes time, and we are getting there.

Cheers,

Bruce
