Currently you cannot build a target for all the configured multiconfigs without
specifying a list. The list can be quite long, requiring to type several lines
of text.
This enhancement is to support globbing so that you can do this,
e.g. instead of:
$ bitbake multiconfig:A:bash multiconfig:B:bash bash
you can do:
$ bitbake multiconfig:*:bash
There are real world use cases where it is desirable to use multiconfig with
two different tasks. For example: SDKs with multiple toolchains but also
containing set of additional host tools, or multiconfig builds requiring one image for
the main CPU(s) and a different co-image for a companion CPU.
For this reason, two variations of the new syntax are supported.
For example, the following:
$ bitbake multiconfig:*:meta-toolhchain
would expand to:
$ bitbake multiconfig:A:meta-toolchain multiconfig:B:meta-toolchain meta-toolchain
However the following:
$ bitbake multiconfig:*:meta-toolhchain hosttools
would expand to:
$ bitbake multiconfig:A:meta-toolchain multiconfig:B:meta-toolchain hosttools
In other words, if the user specified the "default" task explicitly, it replaces the implicit
"default" task.

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.
