Alexandre Belloni 2bdc00fe74 kernel: use oldnoconfig before yes '' | make oldconfig
When using a defconfig, using yes '' | make oldconfig may not result in
the correct configuration being set. For example:

 $ ARCH=mips make qi_lb60_defconfig
 #
 # configuration written to .config
 #
 $ grep USB_ETH .config
 CONFIG_USB_ETH=y
 # CONFIG_USB_ETH_RNDIS is not set
 # CONFIG_USB_ETH_EEM is not set

 $ cp arch/mips/configs/qi_lb60_defconfig .config
 $ yes '' | make ARCH=mips oldconfig
[...]
 $ grep USB_ETH .config
 CONFIG_USB_ETH=m
 # CONFIG_USB_ETH_RNDIS is not set
 # CONFIG_USB_ETH_EEM is not set

Using make olddefconfig solves that but we'll use the oldnoconfig alias
for backward compatibility with older kernels.

 $ cp arch/mips/configs/qi_lb60_defconfig .config
 $ make ARCH=mips oldnoconfig
 scripts/kconfig/conf --olddefconfig Kconfig
 #
 # configuration written to .config
 #
 $ grep USB_ETH .config
 CONFIG_USB_ETH=y
 # CONFIG_USB_ETH_RNDIS is not set
 # CONFIG_USB_ETH_EEM is not set

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, patches against the various components
should be sent to their respective upstreams.

bitbake:
    bitbake-devel@lists.openembedded.org

meta-yocto:
    poky@yoctoproject.org

Most 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.
    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.
