These are recipes where the upstream has moved to GPLv3 and these old versions are the last ones under the GPLv2 license. There are several reasons for making this move. There is a different quality of service with these recipes in that they don't get security fixes and upstream no longer care about them, in fact they're actively hostile against people using old versions. The recipes tend to need a different kind of maintenance to work with changes in the wider ecosystem and there needs to be isolation between changes made in the v3 versions and those in the v2 versions. There are probably better ways to handle a "non-GPLv3" system but right now having these in OE-Core makes them look like a first class citizen when I believe they have potential for a variety of undesireable issues. Moving them into a separate layer makes their different needs clearer, it also makes it clear how many of these there are. Some are probably not needed (e.g. mc), I also wonder whether some are useful (e.g. gmp) since most things that use them are GPLv3 only already. Someone could now more clearly see how to streamline the list of recipes here. I'm proposing we mmove to this separate layer for 2.3 with its future maintinership and testing to be determined in 2.4 and beyond.

Poky
Poky is an integration of various components to form a complete prepackaged build system and development environment. It features support for building customised embedded device style images. There are reference demo images featuring a X11/Matchbox/GTK themed UI called Sato. The system supports cross-architecture application development using QEMU emulation and a standalone toolchain and SDK with IDE integration.
Additional information on the specifics of hardware that Poky supports is available in README.hardware. Further hardware support can easily be added in the form of layers which extend the systems capabilities in a modular way.
As an integration layer Poky consists of several upstream projects such as BitBake, OpenEmbedded-Core, Yocto documentation and various sources of information e.g. for the hardware support. Poky is in turn a component of the Yocto Project.
The Yocto Project has extensive documentation about the system including a reference manual which can be found at: http://yoctoproject.org/documentation
OpenEmbedded-Core is a layer containing the core metadata for current versions of OpenEmbedded. It is distro-less (can build a functional image with DISTRO = "nodistro") and contains only emulated machine support.
For information about OpenEmbedded, see the OpenEmbedded website: http://www.openembedded.org/
Where to Send Patches
As Poky is an integration repository (built using a tool called combo-layer), patches against the various components should be sent to their respective upstreams:
bitbake: Git repository: http://git.openembedded.org/bitbake/ Mailing list: bitbake-devel@lists.openembedded.org
documentation: Git repository: http://git.yoctoproject.org/cgit/cgit.cgi/yocto-docs/ Mailing list: yocto@yoctoproject.org
meta-poky, meta-yocto-bsp: Git repository: http://git.yoctoproject.org/cgit/cgit.cgi/meta-yocto(-bsp) Mailing list: poky@yoctoproject.org
Everything else should be sent to the OpenEmbedded Core mailing list. If in doubt, check the oe-core git repository for the content you intend to modify. Before sending, be sure the patches apply cleanly to the current oe-core git repository.
Git repository: http://git.openembedded.org/openembedded-core/
Mailing list: openembedded-core@lists.openembedded.org
Note: The scripts directory should be treated with extra care as it is a mix of oe-core and poky-specific files.
