[poky] Simple recipe for local kernel/git development

[O'donoghue, Bryan]

Hi all.

I'd like to have bitbake take a kernel in a local git repository and use a defconfig in the same directory as my bitbake recipe, to configure the kernel.

So far I keep running into a requirement to have a "meta" branch which contains various kernel config options. I'd rather not have to store my kernel config in a separate "meta" branch whilst developing/configing the kernel.

My understanding is that I'd have to have the development sources in "master" with the kernel configuration in "meta" - which is not ideal.

In the ideal - we have one "master" branch for the kernel in the git repo - and have a full and complete defconfig applied to that branch - ideal for internal development that is, I'm not suggesting this as a release method.

What's the simple bitbake/yocto-newbie friendly way to accomplish this ? One defconfig is by far my preference.

Here's the recipe so far - is there any way to do what I want to do without a "meta" branch containing the kernel config ?
