I am aware of this, we have since setup a new website, mailing list and as
you have found, git repo. Stefan has been nominated as the maintainer by
Jonas on a previous mail thread.

The issue (as we see it) is that neither Stefan or I have signed PGP keys
by anyone in the web of trust.

I sent this patch set with a cover lett trying to explain of the situation
trying to get some help. Your reponses are very helpful.

Do you think I should just send "git pull" reuqests to Linus with a self
signed pgp key and eplaination to see how it goes?

The bigger question I would have at this point is the value of the code remaining upstream... Five years ago, there was a promise to try to get the toolchain upstream within a year or two; to this day, I don't know that much progress has been made there so this architecture still requires a hodge-podge of tools from various sources to build.

Given the toolchain maintainer's general reluctance to move things upstream, I'd almost be inclined to just remove the OpenRISC arch from the kernel altogether. Are there any other arch's that can't be built with an upstream GCC at this point?

Hi Jonas,
We have tried to get the toolchain in order in the last year. The latest efforts is headlined by a toolchain build tutorial here:

The main toolchain project
binutils-gdb - is upstreamed, I have been working on getting more of the
but there are many patches sitting in our repo on github
I have been working on getting them rebased to 7.11 and
newlib - is upstreamed, with my gdb fixes I have also worked on
fixing some bugs in the last year.
gcc - this is the problem, the gcc code has not been signed over
to the fsf by the original authors. A clean-room rewrite
seems to needed last I checked

The projects are all being maintained on the openrisc github page and we are trying to keep it going.

The attraction of openrisc, I would say, is that its one of the only fully open platforms in the kernel. Its also relatively simple so for hobbyist and students who want to have a 32-bit cpu which they can do 'full-stack' development on it fits a good nitch.

Keeping it upstream means also this code base is not getting stale. But we do need people to look after it and the patches.
