As I think more about it, I think forking edk2 is inevitable.  We need a
clean repo that doesn't include the proprietary binaries.  I doubt
upstream edk2 is willing to remove the binaries.

But this can be quite simple using a combination of git-svn and a
rewriting script.  We did exactly this to pull out the VGABios from
Bochs and remove the binaries associated with it.  It's 100% automated
and can be kept in sync via a script on qemu.org.

I'm not sure if qemu.git is the right location, but we can certainly
host an ovmf.git on qemu.git that embeds the scrubbed version of

Of course, this would enable us to add GPL code (including a FAT module)
to ovmf.git without any impact on upstream edk2.
