Kernel patches in openembedded/yocto

Hi all,

i'm working on a project that use openembedded/yocto project. It's really great to create a full linux distribution and boot images for any type of processor/architecture.
Just for the informations this is how the configs and patches for the kernel are managed:

There a directory that correspond to specific patches/configs we want to apply. Example: https://github.com/openembedded/oe-core/tree/master/meta-skeleton/recipes-kernel/linux/linux-yocto-custom

First a .config file is create from defconfig if it doesn't exists: https://github.com/openembedded/oe-core/blob/master/meta/classes/kernel.bbclass#L310

Then all the cfg file (from the custom directory) are append to the .config and the patch (also in custom directory) are applied to the source.

With this, it use a "default" config file and apply a number of configs/patches for each features needed by specific processor/architecture/board.

Regards,
Yves
