I would like OVMF to follow a plan for GPL that the whole EDK II
community decides on.

I would also like to see EDK II add a (permissively licensed; BSD,
MIT, etc) DriverPkg (DriversPkg?). We discussed this on the list
recently:

http://thread.gmane.org/gmane.comp.bios.tianocore.devel/17544/focus=676

So, related to this, I wonder how the community would feel about a
GplDriverPkg. Would the community allow it as a new package in EDK II
directly, or would a separate repo be required?

With regards to adding it directly into the EDK II tree, here are some
potential concerns that I might anticipate hearing from the community:

* It will make it easier for contributors to choose GPL compared to a
  permissive license, thereby limiting some users of the contribution

* GPL code will more easily be copied into the permissively licensed
  packages

* Some might refuse to look at EDK II entirely if it has a directory
  with GPL source code in it

Of these, I personally only sympathize with the first.

Regarding the separate OVMF repo, my hope is that it is more of a OVMF
specific working area, rather than a 'GPL OVMF'. For example, patches
or features that we've not yet figured out how to upstream, but we
hopefully plan to.

Additionally, it makes sense to use it as needed for OVMF specific
releases. (Ie, OVMF release tags)
