When creating a minimal config or creating a hard baseline for incremental changes, it is often desired to disable all kernel options and then begin building and enabling only what is required. To support this workflow, a new variable KCONFIG_MODE is introduced to contain a hint to the kernel configuration about how the kernel config should be produced. This variable is passed directly to lkc when it is invoked during configuration, so the contents of the variable must be a valid option for the kernel config build. Additionally, when a defconfig is detected, allnoconfig is enabled as the default operation, unless otherwise specified by KCONFIG_MODE.

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
