We are interested. I seem to remember that Serguey had unexplained
latencies issues, so, if you start with his work, please bear this in
mind, there was probably something wrong with his port. A guide
explaining how to port the I-pipe patch on ARM exists:
http://www.xenomai.org/index.php/I-pipe:ArmPorting

The section about chained GPIOs irqs is outdated, if your platform has
some, I will explain how it should be implemented.

Please start from the I-pipe git (git://git.denx.de/ipipe-2.6.git),
merging it with the branch you will use if needed, so that you can
submit a patch only containing the modifications necessary for the
Sheeva platform.

We can also provide you with a root filesystem for validating this platform.
