There's no way to include firmware on debian without actually building it,
and building it, as far as I can see, only works on s390 architecture.
That's why we don't build other firmware stuff - either lack of cross-
compiler on all necessary architectures, or the requiriment to have
actual system of the necessary architecture (virtual or real). It'd be
nice to have it all in one place.

Debian has much stricter policy wrt blobs (DFSG),
and debian builds for more architectures (the firmware,
if it is part of qemu-system-s390 package, needs to be
built on all architectures where this binary package
builts, or it needs to be a separate arch-all package).

I'll take look at all this once again.

It looks like the s390-tools bug can be closed indeed.
