Hi,
here is the core series of our s6000 port.
First comes the nommu patch. Right now we use CONFIG_MMU for
everything that separates the S6000 from existing ports, memorywise.
This is a lot easier and can still be broken up by newer ports when
they have requirements with finer granularity. Furthermore, we have
only this one nommu box here, so we couldn't test an MMU architecture
and therefor not say for sure we didn't break anything ;)
Then comes the core variant stuff. We are the first variant that
needs to ship code files, so there is a prereq patch that allows that.
The inclusion of the GPIO driver is a bit arbitrary. It was the only
one left after stripping out all real peripheral support because we
initially used GPIO in platform_setup(). I send it now to have an
example on variant-specific code and conceptual improvements can then
be excercised on it.
The platform patch is fairly trivial. One more requirement is that
our platform can define the kernel text offset. We can not use a
fixed virtual address (nommu, remember? ;)) but have to provide a
physical one that is within bounds of our actual RAM.
The diffstat looks a bit overwhelming, but note that most of it is the
defconfig, the tensilica core definitions and address definitions
where the core has registers mapped.

Perhaps you have a pointer to a git repository with your changes
that I can clone from.
I can make sure the LX60 and LX200 didn't break. We have a
number of bug fixes and new support for SMP and a new MMU
that we expect to ready for prime time soon. I'd prefer to
use git to test your changes and doing the merge.
How about I add accounts for you, Oskar, and Daniel and
we use the repo(s) as a staging site to test each other's changes
before passing them upstream to Christian and Linus.
It you don't have an external Git repository you could just
ftp a copy and we can add it easily.
