Building the Linux kernel for the BeagleBone Black

I’m trying to install Gentoo on my BeagleBone Black and one of the things to do is to build the kernel. I cloned the kernel repository at https://github.com/beagleboard/linux.git but I cannot find a default .config for the kernel. I can see a default config at arch/arm/configs/bb.org_defconfig. Should I use that as the default .config?

Thanks in advance.

That's why it's there.. :wink:
