Could you expand a bit on why this is needed, and where it will be
used? I have seen those used in various places in some of your packages
in your Git repository, but I am not sure the use cases were actually
valid.

Are these "FLAT (Separate data)" and "Shared FLAT" use cases actually
used in practice by people? I'm not a Blackfin expert, so I don't know
what's used in the field.

Thanks!
