[yocto] BSP in meta layer vs poky

[Kumar Gala]

I was wondering what distinction qualified for a BSP existing in a meta layer vs in poky directly.

For FSL PPC we currently have MPC8315-RDB in poky.  Ideally we'd have one BSP for each major flavor [ associated with a unique compiler / libc target ].  This would end up being something like P2020-RDB (e500v2 core), P204x-RDB (e500mc core), P5020DS (e5500 core - 32/64 bit).

Than everything else would live in the meta-fsl-ppc layer.
