If we use a tag here then bitbake has to connect to the repository to find out the corresponding revision (so it can expand SRCPV which is part of PV, which amongst other things is needed to determine whether or not the package has to be rebuilt.) This occurs at parse time; on machines behind a firewall or with no network access this can be a problem. We wish to avoid unnecessary network accesses and network access in our default configuration during parse time is even worse. Substituting the git revision corresponding to the tag prevents bitbake from having to contact the remote repository in order to expand PV.

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/community/documentation
