[coreboot] Custom Layer or Overlay

[Naveed Ghori]

Hi,
At the Detroit conference someone mentioned that there can is a place to
put proprietary code that is not for checking in to the public coreboot
repo.

I could not find this information on the coreboot website. Maybe I was
looking in the wrong places or using the wrong keyword.

Can some please enlighten me as to where to put such code. I believe it was
a speicif name folder in the root of the repo.

Thanks in advance.

Best Regards,
Naveed
