OpenRISC Port Submission

Hello,
Since February this year I have been working on an OpenRISC clean room rewrite.
http://stffrdhrn.github.io/software/embedded/openrisc/2018/02/03/openrisc_gcc_rewrite.html
As per the article, the old port had issues with some of the owners signing over
FSF copyright. To get around this I discussed options with the group and in the
end I opted for a clean room rewrite.
The new code base has been written by me and more recently Richard Henderson. I
trust that both of us have our FSF GCC copyright's in place.
# Question
How should I go about submitting the port for review? Should I split libgcc and
gcc into separate patches? i.e. One patch mail for ChangeLog? Or would you
prefer a single patch mail? The patch size is around 150k.
Sorry, I understand its a big patch.
# Testing
We have been running the GCC testsuite with newlib and musl libc. The results
are good. See results published in a test build/release here:
- https://github.com/stffrdhrn/gcc/releases/tag/or1k-9.0.0-20180730
# Early Review
If you are interested in reviewing online I have pushed:
- https://github.com/stffrdhrn/gcc/commits/or1k-port-1
To build this requires some of the latest binutils patches submitted here:
- https://gcc.gnu.org/ml/gcc-patches/2018-08/msg01506.html
- git tree: https://github.com/stffrdhrn/binutils-gdb/tree/or1k-6
