See the examples that are already in the kernel-cache, follow one of
them and send a patch to the linux-yocto mailing list.
What ends up in the BSP definition are only the options related to h/w
on the board. General / software options are defined by the
common/included fragments in the configuration repo.

Because we maintain our own reference configurations, and they are
largely consistent across machines and architectures. That is not the
case for in tree defconfigs. People are free to use them for their own
purposes, but that's not what we do for the reference BSPs.
