With no collection [M] and [*] behave the same way. With a collection, you
enable or disable the packages marked as [M]. So by choosing a collection
you can enable or disable groups of packages. This can be done globally as
Alexander described, or for an image. Or you can use a collection for an
image. This is actually described in the documentation. Just search for
'collection' in the docs/ directory.

As mentioned above, you can use collections for an image. Just create a new
rootfs image and collection for each board.
There are some limitations:
- The collections only work with packages not sub-options.
- It must be possible to build all packages in one go, so there cannot be
conflicting header files.
If you use NFS root: Search for _NFSROOT in the documentation. You can
create a separate NFS root for each collection.

PTXDIST_BSP_AUTOVERSION uses 'git describe'. This needs annotated (or
signed) tags. And it expects the tags to be named: SomeTagPrefix-YYYY.MM.n
(<year>.<month>.<bugfixversion>) similar to the ptxdist tags.
