Agreed. I'd like to hear confirmation that the options are at least
valid for the tree as it stands today. If there are configuration
values that are valid only when patches we can't see are applied to
the tree, then splitting the .scc files into the base options and
extended (out of tree), and merging them to linux-yocto and a BSP
layer respectively makes sense.

If I can get that confirmation today, I can merge the changes
immediately.

Cheers,

Bruce
