Um, ok.  Do I need to do anything about this?
I'm also not sure this is too important.
It's GPL compliance so yes, it's very important.

  Most of our firmware blobs come from svn repos which can't be submoduled.
The only firmware blob we're not currently including as a git submodule is
No, there's also OpenHack'Ware (ppc_rom.bin) and s390-zipl.rom.
Alex, what's the source of zipl?

  I believe the main reason is that different boards use different
commits so a single submodule is a bit challenge.  We probably ought to
figure something out here though for the next release.

Can anyone comment a bit more about OpenBIOS?

BTW, OpenBIOS is already actively mirrored on git.qemu.org so all that's
needed is a patch that does a git submodule add with the appropriate commit.
That would be an improvement. Though building various OpenBIOS images
depends on appropriate cross compilers. The situation is actually same
as with SeaBIOS.
Can you do a git submodule add then?

  And as long as we don't have a consistent policy about it, we can just as
well stick with the README file.
We do have a consistent policy :-)  We're just not enforcing it as tightly
as we should.

Any binary we ship in the release tgz's should also have corresponding
source in a submodule.
What about OpenHack'Ware (and PReP machine), should it be deleted?
Yes.  I don't think the source for that is available, correct?  I
don't think we have any other choice.

Debian still holds a copy of the code.

I had thought that the actual binary was from Jocelyn and contains patches that noone else has. In fact, the last commit is:

commit 55aa45ddde3283cdd781326d001f7456bf02f684
Author: j_mayer <address@hidden>
Date:   Mon Oct 1 06:44:33 2007 +0000

    Quickly hack PowerPC BIOS able to boot on CDROM again.

  People have worked recently to
restore prep support that has been broken by various patches, it would
be a pitty to remove it without before asking them.

I'd be very happy to just submodule whatever sources Debian is using.
